JTable KeyListener

First create a JFrame and add JTable with data. Create the following class. Below the JFrame's class

class jTableController implements KeyListener {

   JTable table1;

   public jTableController(JTable table) {
       table1 = table;
   }

   //if you want to get selected data
   private int[] getSelectedCell() {
       int[] xy = new int[2];
       xy[0] = table1.getSelectedRow();
       xy[1] = table1.getSelectedColumn();
       return xy;
   }

   @Override
   public void keyPressed(KeyEvent e) {
       System.out.println("keyPressed");
   }

   public void keyTyped(KeyEvent e) {
       System.out.println("keyTyped");
   }

   public void keyReleased(KeyEvent e) {
       System.out.println("keyReleased");
   }
}

Inside JFrame's constructor add the following code.

       
tblMaterialSupplierDetails.addKeyListener(new jTableController(tblMaterialSupplierDetails)); 

That's it run the project and see.
