java反射机制一个例子

import java.lang.reflect.*;
public class DumpMethods {
  public static void main(String args[]) {
   try {
      Class c = Class.forName("java.util.Stack");
      Method m[] = c.getDeclaredMethods(); 

      for (int i = 0; i < m.length; i++)
        System.out.println(m[i].toString());
   }
   catch (Throwable e){
      System.err.println(e);
   }
  }
}
