How do I print the class structures in a jar file using the javap tool?

Question

I want to list the methods of the class files in the jar using the javap tool. How do I do it so that it lists the methods and members of all the class files in the jar. Right now I am able to do it for just one class at a time.

I am expecting something like if I say

javap java.lang.* 

it should enlist the methods and members of all the classes in java.lang package. If javap is not capable of that, are there any such tools available?

#!/bin/bash # Set the JAR name jar=<JAR NAME> # Loop through the classes (everything ending in .class) for class in $(jar -tf $jar | grep '.class'); do      # Replace /'s with .'s     class=${class//\//.};     # javap     javap -classpath $jar ${class//.class/};  done
