Question

I have a table in my project called tasktable. It retrives data from database (oracle). How can I change the color of the row that has the color in the cell ex. (i,8) automatically when I click the refresh button?

I have tried so many times to put that source code on specific row, but it ended up coloring all the table:

          int count;      
          count = tasktable.getRowCount();
         for (int i=0;i<count;i++)
            { 
                  rr = new Object ();
                   rr = tasktable.getModel().getValueAt(i,8);
                   if(rr.equals("GREEN"))
                   {
                 setBackground(Color.GREEN);
                   }
                    if(rr.equals("red"))
                   {
                       setBackground(Color.red);
                   }
                     if(rr.equals("BLUE"))
                   {
                      setBackground(Color.BLUE);
                   }
                      if(rr.equals("yellow"))
                   {
                     setBackground(Color.yellow);
                   }
                       if(rr.equals("pink"))
                   {
                     setBackground(Color.pink);
                   }
                       if(rr.equals(null))
                   {
                     setBackground(null);
                   }

how can help me out upon this problem ?

Answer 1

setBackground() sets the background color of the JTable, not the background color of each row or cell. You need a TableCellRenderer, as @Recursed said.
