How to Setup Sublime Text 3 for Java in Windows?

Java is one of the most popular and widely-used object-oriented programming languages. Java syntax is similar to C/C++. But Java does not provide low-level programming functionalities like pointers. Also, Java codes are always written in the form of classes and objects. The Java codes are first compiled into byte code (machine-independent code). Then the byte code is run on Java Virtual Machine (JVM) regardless of the underlying architecture. Written by a Google engineer sublime text is a cross-platform IDE developed in C++ and Python. It has basic built-in support for Python. Sublime text is fast and you can customize this editor as per your need to create a full-fledged Python development environment.
