i inherited class defaulttablecellrenderer

    class paintcell extends defaulttablecellrenderer {     public component gettablecellrenderercomponent(jtable table,             object value, boolean isselected, boolean hasfocus, int row,             int column) {         component c = super.gettablecellrenderercomponent(table, value,                 isselected, hasfocus, row, column);         return c;     } } 

and set method table.setdefaultrenderer(object.class, new paintcell());

private jtable table; private int index; private void startanimation() {     timer timer = new timer(1000, new actionlistener() {         @override         public void actionperformed(actionevent e) {             index++;             if (index > table.getrowcount() * table.getcolumncount())                 index = 0;             table.repaint();         }     });     timer.setrepeats(true);     timer.start(); } class paintcell extends defaulttablecellrenderer {     private static final long serialversionuid = 1l;     public component gettablecellrenderercomponent(jtable table,             object value, boolean isselected, boolean hasfocus, int row,             int column) {         component c = super.gettablecellrenderercomponent(table, value,                 isselected, hasfocus, row, column);         int id = row * table.getrowcount() + column;         c.setbackground(id < index ? color.red : null);         return c;     } }
