how to blink table cell continuously after false if statement in swing

Question

In swing application, I am using DefaultTableCellRenderer to flash the table cell when the cell time is equal to system time. I wrote if statement to compare cell t

Answer 1

Create another column of data to store in the TableModel that contains a Boolean value. The data should only be in the model, but the column should NOT be displayed in the JTable.

Then your logic can set the Boolean value to Boolean.TRUE whenever the times are the same. Once the value is true you never set it false. The renderer can now check the Boolean value to do the blinking for the cell and the blinking should continue fore ever.
