   Finding Methods:

        When a class is loaded into JVM, JVM creates method object to store META DATA 

  of a method to get the method objects of a class, we need to call getMethods(). When we 

 call getMethods () then internally an array of type method will be created and stores all  

 methods objects finally JVM returns that method array.

  Syntax:

       Method m[]=c.getMethods();

    

         Method is a class given in java.lang.reflect package. If we call getMethods then it returns 

  including inherited methods from base class. If we want only current class methods excluding 

 inherited methods of base class, we need to call a method getDeclaredMethods().

         Finding method is similar to finding constructor but only difference is there is no return type for constructor there is return type for method.

Example:

        //ReflectDemo5.java

    

          import java.lang.reflect.*;

           public class ReflectDemo5{

           public static void main(String args[]){

                        try{

                           Class c=Class.forName(args[0]);

                           Method m[]=c.getMethods();

                          for(int i=0;i<m.length;m++) {

                                   String s1=m[i].getName();

                                   String rt=m[i].getReturnType().getName();

                                   System.out.println(rt+”    “+s1+”(“);

                                   Class p[]=m[i].getParameterTypes();

                                   for(int j=0;j,p.length;j++)

                                   String s2=p[j].getName();

                                   System.out.println(s2+”)”);

                                }

                             }

                           }

                    Catch(ClassNotFoundException cnfe){

                                 System.out.println(cnfe);

                                }

                       }

                  }
