java - Add Jbutton to Jpanel -

can tell me wrong code trying add buttons jpanel

arraylist<jbutton> buttons = new arraylist<jbutton>();  jpanel createbuttonspane(){    bpanel = new jpanel();    for(int i=0; i<10; i++){       buttons.add(new jbutton(""+i));       bpanel.add(buttons);    }    return bpanel; } 

this code not compile because jpanel not have overload of add() takes array of jbuttons, can not add whole array of buttons jpanel (even if possible, need outside of for()-loop).

simply add button directly jpanel:

jpanel createbuttonspane(){    bpanel = new jpanel();    for(int i=0; i<10; i++){       bpanel.add(new jbutton(""+i));    }    return bpanel; } 

if still need refer individual jbuttons later, add them array in addition:

jpanel createbuttonspane(){    bpanel = new jpanel();    for(int i=0; i<10; i++){       jbutton button = new jbutton(""+i);       buttons.add(button);       bpanel.add(button);    }    return bpanel; }
