Java :How to know in which Row and Column I have clicked on JTable

In this post I have shared you the solution about how to know in which Row and Column of JTable I have clicked.

According to the solution, wherever you have clicked on the JTable the result will be shown using

Message Dialog Box (Check the OUTPUT picture below).

 

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,”You have Clicked on Column :” +(col+1)+ ” : and Row : ” +(row+1));

System.out.println(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:
