Java is a compiled, object-oriented, highly portable programming language. Java is statically typed and features a similar syntax to c programming language. It comes with a large library of readily usable functions, the Java Software Development Kit (SDK). Programs are compiled only once ahead of time into a proprietary byte code and package format that runs inside the Java Virtual Machine(JVM). The JVM is available across many platforms which allows java programs to run almost everywhere without the need to be compiled or packaged again. This makes it a preferred language in many large enterprises' heterogeneous landscapes, but may be perceived as heavy.
Java is owned by Oracle and used by more than 3 billion devices runs it.

An IDE is an acronym for Integrated Development Environment. When it comes to making your java development experience smoother, a java IDE can make it all. Fortunately, there is a multitude of free java IDE's.
A good Java IDE will contain a lot of features, including such things as code refactoring and an in-built debugger. The advanced ones will have syntax highlighted and code completion which can really quicken development. Some of the best Java IDS are as follows.
