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

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”);

setSize(300,300);

topPanel= new JPanel();

topPanel.setLayout(new BorderLayout());

getContentPane().add(topPanel);

setDefaultCloseOperation(EXIT_ON_CLOSE);

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

dataValues = new String[][]     {

                                                {“1″,”2″,”3″},

                                                {“4″,”5″,”6″},

                                                {“7″,”8″,”9″}

                                            };

 TableModel model=new myTableModel();

 table =new JTable( );

 table.setRowHeight(50);

 table.setModel(model);

 scrollPane=new JScrollPane(table);

  topPanel.add(scrollPane,BorderLayout.CENTER);   

  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( )

                                                 {

                                                   super(dataValues,columnNames);

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

                                                 }

                                    public boolean isCellEditable(int row,int cols)

                                     {

                                   return false;                                                                                         

                                    }

                                    }         

            public static void main(String args[])

            {

            SimpleTableTest mainFrame=new SimpleTableTest();

            mainFrame.setVisible(true);

            }         

                        }

OUTPUT:
