Java Basic Problems

JTable Cell Click Event: Click on the JTable Cell and show the Value of that cell.

Sometimes while programming we may need to check and show the value of JTable Cell in click event.

Here, in the given example, I did the coding in such a way that while clicking on a cell of  JTable

It will show the value of that JTable cell in MessageDialog Box.

Code Example:

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import javax.swing.table.*;

class SimpleTableTest extends JFrame


private JPanel topPanel ;

private JTable table;

private JScrollPane scrollPane;

private String[] columnNames= new String[3];

private String[][] dataValues=new String[3][3] ;

public SimpleTableTest()


setTitle(“JTable Cell Click”);


topPanel= new JPanel();

topPanel.setLayout(new BorderLayout());



columnNames=new String[] {“Column 1” , “Column 2” , “Column 3”};

dataValues = new String[][]     {





 TableModel model=new myTableModel();

 table =new JTable( );



 scrollPane=new JScrollPane(table);


  table.addMouseListener(new java.awt.event.MouseAdapter()


public void mouseClicked(java.awt.event.MouseEvent e)


int row=table.rowAtPoint(e.getPoint());

int col= table.columnAtPoint(e.getPoint());

JOptionPane.showMessageDialog(null,” Value in the cell clicked :”+ ” ” +table.getValueAt(row,col).toString());

System.out.println(” Value in the cell clicked :”+ ” ” +table.getValueAt(row,col).toString());





            public class myTableModel extends DefaultTableModel


                                                    myTableModel( )



                                                   System.out.println(“Inside myTableModel”);


                                    public boolean isCellEditable(int row,int cols)


                                   return false;                                                                                         



            public static void main(String args[])


            SimpleTableTest mainFrame=new SimpleTableTest();
