java - How to capture the amount of clicks over a group of loop generated JToggleButtons? -

i have 20 loop-generated jtogglebuttons , need count how many of them active.

private void generarbotones(){         jtogglebutton b;     this.panelcuerpo.setlayout(new gridlayout(4,5));             for(int = 1; i<=20; i++){         b = new jtogglebutton();         b.settext(string.valueof(i));         this.panelcuerpo.add(b);         b.addactionlistener(new actionlistener() {             int clicks = 0;             @override             public void actionperformed(actionevent ae2){                 clicks = clicks + 1;                 system.out.println(clicks);             }                             public void setcantidadboletas(int clicks){                 cantidadboletas = clicks;             }         });     }    } 

the problem here counts how many times each 1 of them clicked instead of count how many of them selected.

ps. tried use (b.isselected()) b needs final access wasn't solution.

if declare jtogglebutton inside loop, can make final:

for (int = 1; i<=20; i++) {     jtogglebutton b = new jtogglebutton(); 

then can use b.isselected:

    b.addactionlistener(new actionlistener() {         public void actionperformed(actionevent evt) {             if (b.isselected())                 clicks++;             else                 clicks--;         }     }); } 

clicks have class variable.
