java - Showing a JLabel -

i want show on concerned cases (row 2 grid), jlabel contained in pawn class.

if(i==1 && (j>-1 && j<8)) { new pawn(colorr); } 

generate pawn on grid, jlabel named 'label' isn't showed.

edit:i corrected things container usage problem jlabel showing , move pawn piece still here.

i enjoy move later pawn position on grid.

i point out 2 major problems saw in code (there can more :))

1. in coordbuttons constructor doing same thing 64 times. according understood want create grid of 8x8. set content pane layout 8x8 grid , add panels it.

    coordboutons() {        super("gridlayout");        setdefaultcloseoperation(exit_on_close);             getcontentpane().setlayout(new gridlayout(8, 8));        (int = 0; < 8; i++) {             (int j = 0; j < 8; j++) {                getcontentpane().add(new caseechiquier(i, j));             }         }         pack();         setvisible(true);  } 

2. in caseechiquier class creating pawn object not display it. instead add label of pawn object jpanel

      if(i==1 && (j>-1 && j<8)) {      pawn p = new pawn(colorr);     add(p.label);    }
