Write a java program to obtain information about methods which are present in a class?

import java.lang.reflect.*;
class MetInfo {
 public static void main(String[] args) {
  try {
   if (args.length == 0) {
    System.out.println("PLEASE PASS THE CLASS NAME");
   } else {
    Class c = Class.forName(args[0]);
    printMethods(c);
   }
  } catch (ClassNotFoundException cnfe) {
   System.out.println(args[0] + " DOES NOT EXISTS");
  }
 }
 static void printMethods(Class c) {
  Method m[] = c.getMethods();
  System.out.println("NUMBER OF METHODS:"+ m.length);
  System.out.println("NAME OF THE CLASS:"+ c.getName());
  for (int i = 0; i < m.length; i++) {
   Class c1 = m[i].getReturnType();
   String rtype = c1.getName();
   String mname = m[i].getName();
   System.out.print(rtype + " " + mname + "(");
   Class mp[] = m[i].getParameterTypes();
   for (int j = 0; j < mp.length; j++) {
    String ptype = mp[i].getName();
    System.out.print(ptype + ",");
   }
   System.out.println("\b" + ")");
  }
 }
}
