JRE,JVM,JIT

JRE (java runtime enviroment )
1)It is like a library , it contains many java files
2)It provides a required file to jit
3)It get a file from jdk by ( java filename) command
4)it is a one of the main component in JDk

JVM(java virtual machine )
1)jvm will get the file from jre

2)It is memory allocation,allocate some memory to run a program
3)jvm is to run a program without any modification

JIT (java in time)
1)jit will get the file from jvm
2)It converts the javafiles into binary code at a run time
3)The jit is used to increases the performance of executation while the java files were convert into binary code

JRE,JVM,JIT-used to perform to run
JDK- used to perform a compeling process
