i have been tearing hair out trying work. appreciated! goal: on jframe, have 2 text fields input numbers. press button sums numbers. display sum on label, located on jframe.

this have far. appreciate help! thank you!

  import javax.swing.*;     import java.awt.*;     import java.awt.event.*;     class homework181 extends jframe     {         private container contentpane;     private jpanel panel1, panel2;     private jbutton button1;     private jtextfield text1;     private jradiobutton radio1;     private jradiobutton radio2;     private buttongroup group;     private actionlistener listener;     private int count;     public homework181(){         settitle("homework181");         setdefaultcloseoperation(jframe.exit_on_close);          panel1=new jpanel();         panel1.setbackground(color.black);         panel1.setpreferredsize(new dimension(300,100));         listener = new listener();         button1= new jbutton("sum");         button1.addactionlistener(listener);         panel1.add(button1);          panel2= new jpanel();         panel2.setbackground(color.yellow);         panel2.setpreferredsize(new dimension(200,100));         text1=new jtextfield(10);         count=0;         text1.settext(""+ count);         text1.addactionlistener(listener);         panel2.add(text1);          contentpane= getcontentpane();         contentpane.setlayout(new flowlayout());         contentpane.add(panel1);         contentpane.add(panel2);          pack();         setvisible(true);     }     public static void main(string[] args)     {         homework181 window= new homework181();      }     private class listener implements actionlistener     {          public void actionpreformed(actionevent e)         {         if (e.getsource()==text1)             count= integer.parseint(text1.gettext());         else             if (e.getsource()==button1);                 text1.settext(""+ ++count);     }          @override         public void actionperformed(actionevent arg0) {             // todo auto-generated method stub          }       }     }  

try instead of create listener class :

 actionlistener listener = new actionlistener() {          public void actionperformed(actionevent e) {             if (e.getsource() == text1) {                 count = integer.parseint(text1.gettext());             } else if (e.getsource() == button1) {                 text1.settext("" + ++count);             }         }     }; 

this function increament value in text1

if want sum of 2 text , create 1 , :

 jtextfield text2 = new jtextfield(10);  text2.settext("" + count);  text2.addactionlistener(listener);  panel2.add(text2); 

then :

create jlabel :

jlabel sum = new jlabel(); sum.settext("" + count); panel2.add(sum); 

then: actionlistener listener = new actionlistener() {

        public void actionperformed(actionevent e) {              count = integer.parseint(text1.gettext()) + integer.parseint(text2.gettext());             if (e.getsource() == button1) {                 sum.settext("" + count);             }         }     };

and instead of of , make action jbutton( because action need) , :

 button1.addactionlistener(new actionlistener() {              @override             public void actionperformed(actionevent e) {                 count = integer.parseint(text1.gettext()) + integer.parseint(text2.gettext());                 text1.settext("" + count);             }         });
