Experiment with Java : Teaching is fun and many a times participants ask interesting questions.

_1.    How can I count the number of methods in a Java class ?
So here it is a simple solution for the same. You can print the count and method headers with this code.

import java.lang.reflect.Method;
/**
 *
 * @author K.A.N. Nancy
 */
public class CountClassMethods {
    public static void main(String args[]){
        Class className=null;
       try{
          className= Class.forName(args[0]);
          Method[] methods= className.getMethods();
           System.out.println("Number of methods in "+className+" = "+methods.length);
           for(int i=0;i<methods.length;i++){
               System.out.println(methods[i]);
           }
       }catch(ClassNotFoundException classNotFoundException){
           System.out.println("Class "+className+" could not be found");
       }

    }
