方法的重载

public class heavy_load {

     /**

      * @param args

      */

     public static void main(String[] args) {

           // TODO Auto-generated method stub

          heavy_load to = new heavy_load();

          to.thism();

          to.thism(1);

          to.thism(1,2);

          

          

     }

     void thism(){ //定以方法

          System. out.println("dige" );

     }

     void thism( int a){//第一次重载

          System. out.println("a: " +a);

     }

     void thism( int a,int y){//第二次重载

          System. out.println(a+" " +y);

     }

}

结果
