what kind of use of jdk

Question

plz tell me on short

Answer 1

Fundamental use, as JDK spell for Java Development Kit, you can't write anything working without ^^

The Java Development Kit (JDK) refers to a set of basic software libraries of the Java programming language, as well as the tools with which Java code can be compiled, transformed into a bytecode for the Java virtual machine.

There are several editions of JDK, depending on the Java platform considered (and of course the version of Java targeted):
- JSE for Java 2 Standard Edition also known as J2SE;
- JEE, the Java Enterprise Edition also known as J2EE;
- JME 'Micro Edition' for the mobile market;
- and so on...

Each of these platforms corresponds to a common base of Development Kits, plus additional libraries specific to the Java platform than the target JDK, but the JDK term is applied indiscriminately to any of these platforms.
