    Default Change Jtable Row and cell Color

    hi
    i have a jtable and I want to change the color of any row whose column value is equal to the value I want
    i use this code
     
    {
     
        public Component prepareRenderer ( TableCellRenderer renderer, int row, int column ){
            String status = (String)jTableAzan.getModel().getValueAt(row, 1);
            System.out.println(status);
            if (jtxtshamsi.getText().equals(status)) {
                setBackground(Color.GREEN);
            }
            Component component = super.prepareRenderer(renderer,row,column);
            //System.out.println("getModel= " + getModel().getValueAt(row,column));
     
            if (getModel().getValueAt(row,column) == null){
                component.setBackground(Color.ORANGE);
            }
            else if (getModel().getValueAt(row,column) != null){
                Object value = getModel().getValueAt(row,column).toString();
                if (isRowSelected(row))
                {
                    component.setBackground(new Color(56,105,138));
                    component.setForeground(Color.WHITE);
     
                    if(value.equals("Friday")){
                        component.setForeground(Color.red);
                    }
                }
     
                else if(value.equals("Friday")){
                    component.setBackground(Color.ORANGE);
                    component.setForeground(Color.red);
     
                }
     
                else{
     
                    if (row%2 == 0){
                        component.setBackground(new Color(255, 255, 253));
                        component.setForeground(Color.BLACK);
     
                    }
                    else {
                        component.setBackground(new Color(208,205,205));
                        component.setForeground(Color.BLACK);
                    }
                }
     
            }
            return component;
        }
     
    }


    But this part of my code does not work

     
     String status = (String)jTableAzan.getModel().getValueAt(row, 1);
            System.out.println(status);
            if (jtxtshamsi.getText().equals(status)) {
                setBackground(Color.GREEN);
            }

    I don't see that code in the renderer code.

    Here is a similar problem: https://www.javaprogrammingforums.co...alue-cell.html

    Can you make a small, simple, complete program that compiles and executes to show the problem?
