swing - ActionListener Unorthodox Infinate Frame Java -

so i'm trying actionlistener work when click on button. whenever create frame though, (the error seems happening in createcomponents() method, , can not see why) jvm keeps generating infinite instances of mycustomframe object.

import java.awt.*; import javax.swing.*; import java.awt.event.*;  public class mycustomframe extends jframe { private jbutton button; private jlabel label; private static final int frame_width = 800; private static final int frame_height = 800;  public static void main(string[] args) {     mycustomframe frame = new mycustomframe();     frame.settitle("my first frame");     frame.setdefaultcloseoperation(jframe.exit_on_close);     frame.setvisible(true); }  public mycustomframe() {     settitle("my custom frame");     setdefaultcloseoperation(jframe.exit_on_close);     setsize(frame_width,frame_height);     setvisible(true);     createcomponents(); }  private void createcomponents() {     button = new jbutton("click me!");     clicklistener listener = new clicklistener();     button.addactionlistener(listener);     label = new jlabel("hello, world!");     jpanel panel = new jpanel();     panel.add(button);     panel.add(label);     add(panel); }  class clicklistener extends mycustomframe implements actionlistener {     public void actionperformed(actionevent e)     {         label.settext("button clicked.");     }  }  } 

class clicklistener extends mycustomframe implements actionlistener 

a mouselistener has no reason extend frame. show every time create listener create frame, creates listener , on.

the code should be:

class clicklistener implements actionlistener
