On the other hand, if the price is an issue, you can also check this Udemy course — Concurrency, Multithreading, and Parallel Computing in Java which won’t cost you more than $10 if you get it on Udemy flash sales which happens every month. For all new Java projects, prefer Gradle, it’s much more concise than Maven. I suggest you master IDEA shortcuts, views, and all other features it offers to become a true Java Master and if you need a resource, I think IntelliJ IDEA Tricks to Boost Productivity for Java Devs is a great place to start with. One of the things I tried with this roadmap is to keep the exposure as short as possible, I have avoided mentioning many alternatives, particularly when it comes to libraries and tools, and stick with industry-standard tools and libraries.
Well, because most of the Java applications you will work with will interact with Database, and it’s excruciating to deal with Database in Java using JDBC and without a proper framework like Hibernate. On the other hand, if the price is an issue, you can also check this Udemy course to Efficient Java Multithreading with Executors, which won’t cost you more than $10 if you get it on Udemy flash sales which happens every month. This is also an excellent course to learn Java concurrency and multithreading in Java. If you can just learn one took, I strongly suggest you learn Docker, it will make your life easy for both the development and deployment of Java applications. The second part is the build tool, which you need to build and deploy your projects like Maven and Gradle.
At the bare minimum, every Java developer should be familiar with JUnit and Mockito, two of the most popular Unit testing and Mock library. The second framework which I recommend every Java developer to learn is the Hibernate, which is based upon JPA . To be accurate, Hibernate came before JPA, but because JPA is a standard API to implement the persistence cross platform mobile development java layer in Java, Hibernate implements it. Spring Framework encourages writing clean code, which is easier to test and maintain by providing you with features like Dependency Injection and Inversion of Control. It also has a rich API for most of the day-to-day tasks, and that’s why every Java developer should learn the Spring framework.
Java offers great APIs like Swing and Java FX for developing GUI clients. Swing was really popular a couple of years back but C# has now taken lead but Java FX is another popular Java API for developing GUI applications in Java. Apart from that, Java is also lucky to have utility libraries like Apache Commons and Google Guava, these two libraries effectively complement JDK libraries. I have also shared a list of 20 Java APIs and libraries for Java developers. There are more advanced libraries that also exist like Cucumber for Business-driven testing, Robot Framework for integration testing, but there is no substitute for JUnit, you will always need that.

And, if you are keen to learn Gradle, I suggest you check out Gradle for Java Developers by another great UDemy instructor, Bharat Thippireddy. First, your IDE, which is your primary tool and can do almost everything you asked for like compile, run, debug, profile, test, compare files and code, refactoring, and much more. These are the building blocks of any program, and a good knowledge of Algorithms and Data Structure is vital for your next job or doing well in your current situation.
Now, the next and another necessary API, a Java programmer, should learn is the Java 8 features, which has completely changed the way Java is coded and programmed nowadays. To become a Java developer in 2022, you must know how to use a Lambda expression, Stream API, Optional classes, and a new Date and Time API. That’s why it’s imperative for Java developers to be familiar with essential Linux concepts and commands related to files, disk space checking, process management, as well as networking commands. You will find that this Java roadmap answers many burning questions like which technologies a Java developer should learn? Mridul said…It will be very helpful if you can share some links for resources to learn the sections mentioned above for beginners.
This is one of the most essential Java API every Java developer should learn. This API provides implementations of standard data structure in Java-like linked list, set, stack, queue, hash table, priority queue, and https://globalcloudteam.com/ others. You should at least be familiar with essential data structures like an array, linked list, hash table, binary tree, queue, stack, and graph as well problem-solving techniques like dynamic programming.
If you are creating global applications that show information in many different languages across the world, then you should have a good knowledge of character encodings. One of the things I tried with this roadmap is that to keep the exposure as short as possible, I have avoided mentioning many alternatives, particularly when it comes to libraries and tools, and stick with industry-standard tools and libraries. In Android, programming is done in two languages JAVA or Kotlin and XML. The XML file deals with the design, presentation, layouts, blueprint, etc (as a front-end) while the JAVA or KOTLIN deals with working of buttons, variables, storing, etc (as a back-end). And the biggest confusion for an Android beginner is which language to choose between Java and Kotlin? Android is an open-source operating system, based on the Linux kernel and used in mobile devices like smartphones, tablets, etc.
Javin paulsaid…Hello Mridul, I have shared a lot of resources like books and courses, even in this article. That’s all about the2022Java Developer Roadmap.This is an excellent resource to learn Java in 2022 and become a better Java developer. If you want to learn JUnit and Mockito, I have already shared a lot of resources like books and courses, you can check those to learn more. The current version of Eclipse Microprofile is 3.2, and it’s a useful Java framework to learn in 2022. This is another framework I recommend every Java developer to learn in 2022 and going forward. Spring Boot took Spring’s philosophy of simplification and made it easy to work with Spring itself.
- This is one of the most popular Java frameworks, and literally, almost every single Java application I have worked on in the last 5 years, uses this framework.
- The current version of Eclipse Microprofile is 3.2, and it’s a useful Java framework to learn in 2022.
- Unfortunately, there are not many dedicated resources on teaching Java IO and Java NIO API, but The Complete Java Masterclass is a great resource to master this API.
- It’s a polyglot framework and allows you to create an application using Java, Kotlin, or Groovy.
- If you want to learn more about MicroNaut, you can also check out Learn Micronaut — cloud-native microservices with Java course on Udemy.
- Now, the next and another necessary API, a Java programmer, should learn is the Java 8 features, which has completely changed the way Java is coded and programmed nowadays.
It is an operating system that has a huge market for apps. That’s all about the 2022 Java Programmer and Developer Roadmap. This is an excellent resource to learn Java in 2022 and become a better Java developer. I have kept it simple so that most people can follow it and only included the important stuff. If you want to develop a GUI application like NetBeans, one of the famous Java editors which are also written in Java then you can learn Java FX in 2022. I wouldn’t advise learning Swing unless you are working for a bank that is paying you thousands of dollars per month maintaining their Swing-based trading GUI.
As an application developer, you just need to know the API as all vendors provide an implementation of those APIs. You just need to include their JAR file into the classpath and your code will work fine. If you want to learn JUnit and Mockito from scratch, then I also suggest you join Learn Java Unit Testing with Junit & Mockito in the 30 Steps course by In28Minutes on Udemy. It’s a practical and hands-on course to get started with both these libraries. Btw, if you truly want to master Hibernate or looking for an advanced Hibernate course then Vlad Mihalcea’s High-Performance Java Persistence book and the course is the best resource for anyone. After Java Collections, the next, most crucial API in Java is about multithreading and concurrency, and I firmly believe that if you want to be a competent Java developer, you must have a solid understanding and command of Java Concurrency API.
It will take anywhere between 6 to 8 months to master these concepts. If you need more resources, you can check out this list of courses to learn all new Java features in 2022. If you need a resource, you can check out this list of courses to learn all new Java features in 2022. There are plenty of resources and videos available online and it’s confusing for developers where to start learning all the concepts. Initially, as a beginner, if you get overwhelmed with so many concepts then don’t be afraid and stop learning. If you need more resources, you can also check out my earlier articles about the best design patterns books and courses to learn Object-Oriented Design patterns in depth.
The contents of this blog, including text, original pictures and ideas are the sole property of Javarevisited. But, You are more than welcome to to use one photo from the blog with credit and a link back to the original post. I suggest you go through that list, chances are that you already have half of them but if you don’t learn them they are very, very useful and help you to write better Java programs and deliver faster. Each of them has its different property like ArrayList is a dynamic array that can grow, HashMap is a standard implementation of the hash table and can be used to store key-value pairs. After you got an idea about the different components of Android then start exploring some simple UI design which is given below. There are some necessary building blocks that an Android application consists of.
There is no doubt that every programmer should know Git and Github as they are the standard in terms of version control and code repository. If you want to learn and master Git and Github, you can check this list of books and courses to learn Design patterns. Javin paulsaid…Hello Zoraiz, you should focus on core Java concepts like Java basics, data types, then Java Collections, Multi-threading and Concurrency, and then slowly about design principles, patterns and finally something about JVM. To start with, you should check out my list of Top 10 Java Programming courses for beginners.
Do you need to learn all the concepts from a book or you should go with some online tutorials or you should learn Android by doing some projects on it? So in this article, we are going to discuss all these things in detail. When it comes to a mocking library, you have a couple of choices like PowerMock, Mockito, and EasyMock. Still, I strongly suggest you learn Mockito because it’s a vast library, and also many Java developers and companies are doing that. It is slowly becoming the standard library for creating mock objects in Java. While learning Spring Boot and Spring Cloud is sufficient for developing Microservices in Java, there is a couple of more advanced frameworks you can explore, like Eclipse’s Microprofile, Micronaut, and Quarkus.
After Working As A Software Developer And Contractor For Over 14 Years For A Whole Bunch Of Companies Including Csc
Do it regularly and also start learning one by one new concept on Android. It will be very better to join some workshops or conferences on Android before you start your journey. The goal of Eclipse of MicroProfile is to define standard APIs for building microservices and deliver portable applications across multiple MicroProfile runtimes. The current version of Eclipse Microprofile is 3.2, and it’s a useful Java framework to learn in 2022. If you want to learn and master Design Patterns, particularly OOP Design patterns then I suggest you join the Design Patterns in Java course by Dmitri Nestruk on Udemy.
Most of the libraries also now stop supporting versions lower than Java 8, which means you have to learn Java 8 features now than later. It’s already 5 years since Java 8 was released, so you literally have no excuse left. Unfortunately, there are not many dedicated resources on teaching Java IO and Java NIO API, but The Complete Java Masterclass is a great resource to master this API. You will find a lot of essential concepts from this API in this course. This is another common tech skill that every Java developer should learn as it will help you to troubleshoot backend issues.

If you are interested, you can find a more exhaustive list of separate blog pots, which I have listed in the further learning section. Anyway, let’s go through this Java Developer RoadMap to understand how to become a Java developer in 2022. Kotlin is a cross-platform programming language that may be used as an alternative to Java for Android App Development. It has also been introduced as a secondary “official” Java language in 2017. The only sizable difference is that Kotlin removes the superfluous features of Java such as null pointer exceptions.
This Roadmap contains my years of experience and the unobstructed path of how to become a Java expert. It answers many burning questions like which technologies a Java developer should learn? And, which framework a Java developer must absolutely learn. You can also build and deploy Java FX applications on Raspberry PI, one of the small but powerful computers. If you are interested in that, Frank Delporte has a great course Use Java and Java FX on a Raspberry PI for beginners. Testing is an essential skill for any Java developer, particularly unit testing, integration testing, and automation testing.
I know, it’s a lot of stuff, and that’s why I suggest you join an in-depth course like Java Concurrency in Practice bundle from Heinz Kabutz, a Java Champion, and authority when it comes to concurrency and design patterns. Before going to Java-specific stuff, let’s go through some mandatory skills which are required for both core Java developers as well as full-stack Java developers. These are the essential skills for any programmer or software developer and will serve you for a long time. If you want to learn more about MicroNaut, you can also check out Learn Micronaut — cloud-native microservices with Java course on Udemy. There are not many courses but this one and MicroNaut documentation are sufficient to start developing applications with MicroNaut.
Intellij Idea Tricks To Boost Productivity For Java Devs
I highly recommend Java programmers to learn Git and Github and if you already worked with Git then you can also level up your Git skills and If you need a resource then you can check out The Git Complete Guide on Udemy to start with. Hello guys, if you want to become a professional Java developer or want to take your Java skill to next level but are not sure which technology, tools, frameworks, and library you can learn then you have come to the right place. I have been sharing a lot of roadmaps like a Web developer RoadMap, DevOps engineer RoadMap, and React.js developer RoadMap. In short, one of the best platforms for Java developers to create an application and something worth learning in 2022. While learning Spring Boot and Spring Cloud is sufficient for developing Microservices in Java, there is a couple of more advanced frameworks you can explore, like Eclipse Microprofile, Micronaut, and Quarkus.
The 2022 Java Programmer Roadmap
This is a great course to learn the modern implementation of classic design patterns in Java. While there is a bright future for AI and Machine learning, its not true that you will only have that job in future. Of course you need to keep yourself up-to-date with Cloud, DevOps, and other Software development tools and practices, but that’s part of every developers job.
Micronaut is a modern, JVM-based, full-stack framework for building modular, easily testable microservice and serverless applications. It’s a polyglot framework and allows you to create an application using Java, Kotlin, or Groovy. Some of the key talking points of Micronaut are reduced startup time, blazing-fast throughput, and minimal memory footprint.
These loosely coupled components are bound by the application manifest file which contains a description of each component and how they interact. I suggest you go through that list, chances are that you already have half of them but if you don’t learn them they are very, very useful and help you to write better Java programs and deliver faster. At least you should know about all everyday objects like ArrayList, HashMap, HashSet, LinkedHashSet, TreeSet, etc. Kubernetes is a next-level tool and not really needed for all JAva developers, particularly if you are not in DevOps and managing things like scaling and deployment but it’s good to know from a knowledge perspective.
Just like Spring makes it easier to create a Java application, Spring Boot makes it easier to create a spring-based Java application. So before jumping into the complete Roadmap of Android one should have a clear goal in his/her mind that why he/she wants to learn Android? Or do you want to build your apps to start your business? For example, if you want to learn Android for your college Academic projects then it’s enough to just learn the beginner things in Android. Similarly, if you want to build your long term career then you should learn the professional or advanced things also.
