I want to display correctly in the textbox data when selecting any rows from multiple tables.
table1: 1. If I click on any row of Table 2 I also get table1: 1 (but it should be table2: 1. ) .import java.awt.BorderLayout;

Don't play around with the FocusListener. There is no need to clear the table selection. Users don't like to have the row selection disappear as they move from tab to tab. So get rid of the FocusListener and leave the row selection as is.
Instead you can get the currently focused table by doing something like:
menuItemOpen.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
JMenuItem mi = (JMenuItem)e.getSource();
JPopupMenu popup = (JPopupMenu)mi.getParent();
JTable table = (JTable)popup.getInvoker();
if (table.equals(table1))
{
textField.setText(table1.getValueAt(table1.getSelectedRow(), 0).toString());
}
else if (table.equals(table2))
{
textField.setText(table2.getValueAt(table2.getSelectedRow(), 1).toString());
}
else if (table.equals(table3))
{
textField.setText(table3.getValueAt(table3.getSelectedRow(), 2).toString());
}
}
});
