Building an method call tree using .class file (java)

Basically what you will have to do is parse a compiled java file (.class) and a method to the program to build a call tree. Written ClassParser code will be provided as well as detailed instructions on the requirement. Example use of program will be like : java classparser [login to view URL] method1 Example Output (call tree) will be like : method1() method2() method4(int, string) method3() method5() method6(double, int) Please note that you will insert only an .class file and method name (on the class) and everything should be done by bytecode parsing and constant pools etc: Hoping to get this done soon
