Java has different versions that starts from 1.0 and till now, java 10 has been released.
To know java better we will understand some key points :
- Bytecode : This is a highly optimized set of instruction code (.class file).
Bytecode is created when we compile the java source file.
Due to the bytecode, Java is platform independent in nature. - JDK : JDK (Java Devlopment Kit) is a full development kit for JAVA programming.
To create a java application, you must install JDK as it contains java compiler as well. - JRE : To run java applications, we only need JRE (Java Runtime Environment) on our system.
