What is Java and why do you need it?

Java is one of the most popular programming languages in the world, and it is used to create applications for various purposes, such as web development, mobile development, desktop development, gaming, data analysis, and more. But what exactly is Java and why do you need it?

Java is a programming language and a platform

Java is both a programming language and a platform. A programming language is a set of rules and syntax that allows programmers to write instructions for computers. A platform is a software environment that provides tools and libraries for running and developing applications.

Java as a programming language is known for its simplicity, readability, portability, object-oriented design, and high performance. Java as a platform consists of two main components: the Java Virtual Machine (JVM) and the Java Application Programming Interface (API).

Java enables you to run applications on different devices

The JVM is a software layer that interprets and executes Java bytecode, which is a compact and optimized form of Java code. The JVM allows Java applications to run on any device that has a compatible JVM installed, regardless of the operating system or hardware. This means that you can write a Java application once and run it on Windows, Linux, Mac OS, Android, iOS, or any other platform that supports Java.

The API is a collection of predefined classes and interfaces that provide various functionalities for Java applications. The API includes core features such as input/output, networking, graphics, security, database access, and more. The API also includes optional features such as Swing, which is a graphical user interface toolkit, or JDBC, which is a database connectivity framework.

Some of the new features and improvements in Java 12 are:

• Switch expressions: This feature allows you to use switch statements as expressions that can return values. It also simplifies the syntax of switch statements by allowing multiple cases to be grouped together with commas.

• Raw string literals: This feature allows you to write string literals that span multiple lines without needing escape sequences or concatenation operators. It also preserves the indentation and formatting of the string literals.

• Default CDS archives: This feature allows you to improve the startup time of your Java applications by using class data sharing (CDS) archives. CDS archives are files that contain pre-processed classes from the JDK or your application. By using CDS archives, you can avoid loading and parsing classes every time you run your application.

• JVM constants API: This feature allows you. JVM constants API: This feature allows you to model nominal descriptors of key class-file and run-time artifacts, such as classes, methods, fields, and method handles. It also enables dynamic language compilers to generate classes dynamically.

• Shenandoah: This feature is a new low-pause-time garbage collector that reduces the impact of garbage collection on the performance of your Java applications. It works by evacuating the live objects from the heap regions that are being reclaimed, while the application threads are running concurrently.

These are just some of the new features and improvements in Java 12. You can find more details on the official Java website.

How to check if you have Java installed and what version you have?
