Understanding Java Byte Code

Question

Often I am stuck with a java class file with no source and I am trying to understand the problem I have at hand.

Answer 1

To view bytecode instruction of class files, use the javap -v command, the same way as if you run a java program, specifying classpath (if necessary) and the class name.

Example:

javap -v com.company.package.MainClass
