Hi

Please any one tell me the differences between these 2 words (JDK & JRE), In which situations these 2 are used.


Thanks

JRE contains all the required java library but it does not contain tools to compile java program etc.

Visit this link to see the difference.

The "JDK" is the Java Development Kit. I.e., the JDK is bundle of software that you can use to develop Java based software. The "JRE" is the Java Runtime Environment. I.e., the JRE is an implementation of the Java Virtual Machine which actually executes Java programs.

Typically, each JDK contains one (or more) JRE's along with the various development tools like the Java source compilers, bundling and deployment tools, debuggers, development libraries, etc.
