What is the Difference between JDK, JRE and JVM.

 Answer :

 JDK : JDK (Java Development Kit) is a software development

 environment used for developing java applications. It includes

 JRE(Java Runtime Environment), an interpreter/loader, a compiler(javac)

 and other tool needed for java development.

 JRE : We need an environment to run a java program. Java Runtime Environment

 provides the minimum requirement for executing a java application or program.

 It consists of JVM and library classes.

 JVM : Java Virtual Machine is a very important part of both JDK and JRE. JVM

 is responsible to execute a java program line by line. That why, JVM is also

 known as Interpreter

 Note:

JDK = JRE + Development Tools

                            JRE = JVM + library classes
