Installation of IDE
An integrated development environment, or IDE, is a piece of software that offers fundamental tools for creating applications, such as an editor, compiler, and debugger. It is a piece of software that makes it simple and efficient to write and debug Java programmes.
Most IDEs have features like syntax highlighting and code auto-completion that make it easier for programmers to write code. Compilers, code editors, interpreters, and debuggers are frequently included in IDEs. Additionally, Java IDEs feature language-specific components like TestNG and JUnit Testing as well as build tools like Ant and Maven.
There are many different IDEs for Java, including IntelliJ IDEA, Eclipse, NetBeans, MyEclipse, Greenfoot, DrJava, Xcode, BlueJ, JDeveloper, and JCreator. For its Java Integrated Development Environment, IntelliJ IDEA is renowned. One of the best benefits of using IntelliJ IDEA is its user-friendly user interface, which is one of the requirements for application development and testing (UI).
