Differences between Java Compiler,JIT Compiler,Java Interpreter

Java Compiler->Java compiler just convert .java programs into .class files,

                   that means converting our source code into byte code.

JIT Compiler->JUST IN TIME COMPILER is the part of the Java Virtual Machine (JVM)

                   that is used to speed up the execution time. JIT compiles parts of the byte code

                   that have similar functionality at the same time, and hence reduces the amount of

                   time needed for compilation. Here the term “compiler” refers to a translator from

                   the instruction set of a Java virtual machine (JVM) to the instruction set of a specific CPU.

Java Interpreter->JAVA INTERPRETER converts total Byte code into machine dependent code,

                   If JVM use only interpreter the performance of JVM will slow,

                   so JVM uses JIT compiler and Interpreter both.
