Java Programming language is changing rapidly. Now there is a new release every six months and it's hard to keep up-to-speed with new Java features.

So what should a Java programmer do to keep himself up-to-date and without missing key features? Well, instead of learning all-new features you can focus on some of the key Java features which can make Java development easier and has the potential to improve code quality and developer productivity.

In this article, you will learn about 5 new Java features since the Java 9 release

These are the Java features that will not only help you to write better code but also be worth knowing from a Java interview point of view and that's why I think every Java developer should learn in 2024.

Modules 

made your Java application smaller and faster by reducing unwanted packages. You are allowed to include what you really need. Then var comes which makes it easier to declare local variables like Javascript and other programming languages.

Switch expression made the branching easier and improved the readability aspect of the code. You can now write expressions, combine multiple cases to produce a single result, and much more. You will see in the example how clear and concise new switch statements are.

Sames goes to Text Block which ended the pain of escaping string for multiple lines. Now, it's much easier to produce multiple-line output from a Java program.

For Java developers, mastering certain key features and concepts can greatly enhance their skills and make them more proficient in Java development. Here are five essential features that every Java developer should learn:

1. Object-Oriented Programming (OOP): Java is an object-oriented programming language, so a solid understanding of OOP principles is crucial. This includes concepts like classes, objects, inheritance, polymorphism, and encapsulation.
2. Collections Framework: Java's Collections Framework provides a set of classes and interfaces for working with collections of objects, such as lists, sets, and maps. Understanding how to use these collections effectively is essential for developing efficient and maintainable Java code.
3. Exception Handling: Java uses exception handling to manage errors and exceptional conditions in code. Knowing how to use try-catch blocks, throw and throws keywords, and how to create custom exceptions is important for writing robust and reliable Java applications.
4. Multithreading and Concurrency: Java supports multithreading, allowing developers to write code that can perform multiple tasks simultaneously. Understanding concepts like threads, synchronization, and concurrency pitfalls is essential for developing high-performance, concurrent Java applications.
5. Java I/O (Input/Output): Java provides a rich set of classes and interfaces for working with I/O operations, such as reading from and writing to files, streams, and sockets. Knowing how to use these I/O classes effectively is important for handling data input and output in Java applications.

By mastering these essential features, Java developers can write more efficient, maintainable, and reliable code, and become more proficient in Java development overall.
