How to convert java source code to byte code to run java language

Java Could not Compile into an exe file extension on the computer, java processing with byte code, so to compile java we need to install JDK (Java Development Kit) that compile from the normal code into the Byte Code. Java Run with JRE (Java Runtime Environment). Normally JRE already include in JDK so we don't need install both separately.
