Many times, we need to understand what a compiler is doing under the hood. How java statements we are writing, will be reordered and executed. Also, we need to see the byte code for learning purpose also, I do it seldom.

2. javap -c [Your class name].class > bytefile.bc

3. Open bytefile.bc

Look at example below, bytecode is demo as below
