The java interpreter or JVM (Java Virtual Machine) is not able to execute the java source code for a program. The java source code first needs to be compiled into bytecode that can be processed by JVM.
Producing bytecode make the program platform independent as each platform has its own JVM. It is also possible to directly write bytecode, bypassing the need to compile, but that would be tedious job and also not good for security purpose as the compiler checks for various errors in a program.

Difference between a java complier and the Java JIT?
A java compiler takes Java source code and turns it into Java bytecode, which can then be run by the java virtual machine.Using JIT means that the java code will be compiled and executed at the time that you run the program, which will slow down the program because it has to compile the code at the same time that it runs.
