java - JButton ActionListener not responding -

i couldn't find answer anywhere else online, came here. apologize in advance if mistake in code obvious; i'm still quite new java swing. here's what's going on: have created jbutton named toggleelevators, , want change text when clicked. have created actionlistener , added toggleelevators. want right jbutton change text when clicked click me clicked.

first, here's picture of jframe looks when executed:

note: there third class, purely drawing picture on left. has nothing gridlayout or jbutton.

run class (created frame , adds toggleelevators jbutton:

import java.awt.color; import java.awt.eventqueue; import java.awt.gridlayout;  import javax.swing.jframe;  public class run extends input{  input = new input();  public static void main(string[] args) {     new run(); }  public run() {     eventqueue.invokelater(new runnable() {         @override         public void run() {             jframe frame = new jframe("elevators");             frame.setlayout(new gridlayout(0, 3));             frame.setdefaultcloseoperation(jframe.exit_on_close);             frame.add(new elevators(color.magenta, true));             frame.add(new elevators(color.orange, false));             frame.setsize(800,600);             frame.setresizable(false);              frame.getcontentpane().add(toggleelevators); //adds toggleelevators button jframe             i.addbuttonlisteners(); //calls method defined in input class, adds actionlistener toggleelevators button              frame.setlocationrelativeto(null);             frame.setvisible(true);         }     }); }  } 

input class (creates toggleelevators jbutton , actionlistener):

import java.awt.event.actionevent; import java.awt.event.actionlistener;  import javax.swing.jbutton;  public class input { jbutton toggleelevators = new jbutton("click me.");  public void addbuttonlisteners() {     toggleelevators.addactionlistener(new toggleelevatorslistener()); }  class toggleelevatorslistener implements actionlistener {     public void actionperformed (actionevent event) {         toggleelevators.settext("clicked.");         system.out.println("actionlistener called."); //i know actionlistener not being called because line not being printed out in console     } } } 

your run class extends input, has input named i. you're adding this.toggleelevators frame, you're adding listener i.toggleelevators.

remove i field class. forget defining , extending input class. doesn't serve purpose, , seems confuse more you.
