Write a java program to obtain constructors of a class?

class ConsInfo {
 public static void main(String[] args) {
  if (args.length == 0) {
   System.out.println("PLEASE PASS THE CLASS NAME..!");
  } else {
   try {
    Class c = Class.forName(args[0]);
    printConsts(c);
   } catch (ClassNotFoundException cnfe) {
    System.out.println(args[0] + " DOES NOT EXISTS");
   }
  }
 }
 static void printConsts(Class c) {
  java.lang.reflect.Constructor Cons[] = c.getConstructors();
  System.out.println("NUMBER OF CONSTRUCTORS:" + Cons.length);
  System.out.println("NAME OF THE CONSTRUCTOR:"+c.getName());
  for (int i = 0; i < Cons.length; i++) {
   System.out.print(c.getName() + "(");
   Class cp[] = Cons[i].getParameterTypes();
   for (int j = 0; j < cp.length; j++) {
    System.out.print(cp[j].getName() + ")");
   }
   System.out.println("\b" + ")");
  }
 }
}
