The Java Development Kit (JDK) provides all the tools, executables, and binaries required to compile, debug and execute a Java Program within the Java Environment. The Java Virtual Machine (JVM) provides java functions such as memory management, garbage collection, and security. Finally, the Java Runtime Environment (JREA) is the implementation of the JVM providing the platform to execute java programs.

Apart from this, there are also so many great features which are given below:
