자바 스윙쓰고있고 창1번에서 버튼누르면 새창 띄우는거 만들어보려고하는데


버튼추가 이런건 생략하고 창1의 버튼액션




 @Override

   public void actionPerformed(ActionEvent e) {

    Object ob = e.getSource();

   

    if(ob==btnaccept)

    {

    new prac_2("성공");

    }

   }




창 2번클래스


public class prac_2 extends Frame implements ActionListener{



Container cp;

public prac_2(String title){

super(title);

this.setBounds(250, 100, 1175, 500);

cp.setBackground(new Color(255, 255, 255));

     initDesign();

     this.setVisible(true);

}


public void initDesign(){

}


public void start() {

this.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

setVisible(false);

dispose();

}

});

}



@Override

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

}


}


이렇게하래서 그대로했는데 버튼 눌러도 암것도안나옴ㅠㅠ
