Hello Folks , Welcome to my new blog . Hope you are doing well . If you are learning java here I will tell you 10 ways to become a better Java developer in 2022 , easiest way .

1 . Learning Java 8

The foremost important thing is learning java 8 for a Java Developer. There are many very well-known coders and experienced java developers with seven to ten years of experience in this field. Regardless of these, there are many programmers who may not have written any line of code using the features of Java 8 like lambdas and the Stream API.There might be some point in the career where the learning becomes slow, but if one doesn’t act then they will be left behind. These days almost every job related to JAVA developments, Java8 skills are required, and if someone is lacking these skills then it is difficult to do well.

The old-style:

Arrays.sort(testStrings, new Comparator<String>(){ @Overridepublic int compare(String s1, String s2){ return(S1.length()-s2.length());

New Style


2 . Learning the Spring Framework(Spring Boot)

When it comes to the construction of a web application, REST APIs, and microservices, the vast majority of companies choose to make use of Spring frameworks. These include Spring MVC, Spring Boot, and Spring Cloud. This preference is shared by a large majority of people in the corporate sector. Because of this, becoming familiar with Spring is quite vital for a Java developer to undertake if they intend to perform successfully in the competitive business environment of the modern era.

In addition to this it encourages the implementation of industry best practices, like dependency injection, and boosts the testability of your program, both of which are essential requirements for software that is built in this day and age. In addition to this, it improves the testability of your software by encouraging the implementation of industry best practices and promoting the application of industry best practices, such as dependency injection. Furthermore, it promotes the testability of your software by improving its testability.

3. Learning Unit Testing:

Skills in unit testing are often cited as the single most important factor that differentiates a good Java developer from an average Java developer.The code of a decent and professional Java developer almost usually includes unit tests, and if they are truly a rockstar developer, it will be evident from both their code and their tests. Testing has also come a long way, with various tools accessible to Java developers for unit testing, integration testing, and automation testing respectively. One can spend a good portion of 2018 polishing your testing skills in Java, but for those who are new to the Java world and unit testing, the ideal library, to begin with, is JUnit. One can spend a significant portion of 2018 honing your testing abilities in another language. Every single Java developer ought to be aware of the fact that the most recent version of JUnit, which is version 5, is both powerful and flexible.

4. Learn APIs and Libraries

If you have worked with excellent Java developers, you may have observed that they have a comprehensive understanding of the Java ecosystem as a whole, of which APIs are a significant component. Java is the most popular and widely used programming language in the world, and it has developed to the point where there are dozens of libraries and application programming interfaces (APIs) accessible for practically any task. You are not expected to be familiar with each and every one of these APIs, but you should be familiar with some of the more important ones. For example, you should be familiar with JSON processing APIs like Jackson and Gson, XML processing APIs like JAXB and Xerces, and unit testing libraries like Mockito and JUnit. In 2018, if you are unfamiliar with them, you will have the opportunity to become educated on them or at the very least have an overview of them. You can get started by looking at my list of the top 20 Java libraries that every Java developer ought to be familiar with. This list includes libraries from essential categories such as parsing, bytecode manipulation, concurrency, collections, and more.

5. Learning the JVM’s Internals

If you are serious about becoming a rockstar Java developer, then you must invest time learning JVM internals, e.g., what are the different sections of the JVM, how they function, JIT, JVM options, Garbage collection, and collectors, etc. If you know the JVM well, you can design sturdy and high-performance Java programs, and that’s what rockstar Java developers do. As part of this, you should also understand how to profile your Java application and how to detect performance bottlenecks.

6. Learning the Design Patterns

If you are developing a Java program from scratch, then the vast majority of the time you are writing code that is object-oriented, and design patterns are solutions that have been tried and tested to solve common problems. You may make your application more flexible and easier to alter in the future if you are familiar with these best practices and include them in your code. Because more Java engineers are also aware of design patterns, this not only enhances the quality of the code overall but also the documentation. Therefore, people will comprehend your solution in a relatively short amount of time. However, you shouldn’t only concentrate on the coding part; instead, you should understand the essence of it and be creative. Rewriting patterns should be done with Java 8 capabilities such as lambdas and Streams.

7. Learn DevOps Tools

A working grasp of DevOps is an incredibly required skill set to acquire for a modern Java developer, and it is becoming increasingly important in the industry. You should at the very least be familiar with the concepts of continuous integration and continuous deployment, in addition to the role that Jenkins plays in enabling one to engage in practices such as these. It is of even greater significance for senior Java developers, as it is common for them to be in charge of establishing best practices for coding as well as building environments, build scripts, and guidelines. Because of this, it is even more likely that senior Java developers will be responsible for building environments, build scripts, and guidelines. Because of this, it is even more probable that more experienced Java developers will be the ones responsible for creating best practices.

8 .Learning kotlin:

It is a wonderful programming language that was developed by JetBrains, the same firm that was responsible for the development of IntelliJ IDEA, and it was developed by JetBrains. JetBrains is also responsible for the development of IntelliJ IDEA. In addition, Google said in 2017 that it would use it as the primary language for the development of applications for operating systems based on the Android platform. As a direct result of applying it, not only will you become more productive, but you will also discover that it is a great deal simpler to get started designing for Android.

9 . Learning microservices:

The architectural field is always undergoing new developments, and an increasing number of businesses are abandoning monolithic app architecture in favor of microservice architecture. To be able to make the most of the recent trend that has been happening, it is essential for Java developers to educate themselves on the architecture of microservices as well as the process of constructing microservices using Java. Only then will they be able to capitalize on recent the wave that has been happening. Because the Spring Framework integrates both Spring Cloud and Spring Boot, we can now let out a sigh of relief because we no longer have to worry about this issue. The process of constructing Java-based microservices is made easier by the presence of both of these components.

10 . Learn IDE better:

Better Java developers tend to be very skilled with the tools that they use, which is one of the most significant qualities they may possess. They are not only more familiar with their tools than the typical software engineer, but also have a deeper familiarity with those tools. Since integrated development environments (IDEs) such as Eclipse, NetBeans, and IntelliJ IDEA are some of the most significant tools for a Java programmer, it makes sense to devote some time to expanding one’s knowledge of these technologies.
