Java Program to retrieve the value from a cell in a JTable
To retrieve the value of a cell, use the getValueAt() method. As parameters, set the row and column index value for which you want the cell value −
int rIndex = 5; // row index int cIndex = 1; // column index Object ob = table.getValueAt(rIndex, cIndex);
Display the cell value in the Console −
System.out.println("Value = "+ob);
The following is an example to retrieve the value from a cell −
Example
package my; import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JRootPane; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo { public static void main(String[] argv) throws Exception { JFrame frame = new JFrame("Demo"); JPanel panel = new JPanel(); String data[][] = { {"Australia","5","1"}, {"US","10","2"}, {"Canada","9","3"}, {"India","7","4"}, {"Poland","2","5"}, {"SriLanka","5","6"} }; String col [] = {"Team","Selected Players","Rank"}; DefaultTableModel tableModel = new DefaultTableModel(data,col); JTable table = new JTable(tableModel); table.getTableHeader().setResizingAllowed(false); Dimension dim = new Dimension(50,2); table.setIntercellSpacing(new Dimension(dim)); int rIndex = 5; // row index int cIndex = 1; // column index Object ob = table.getValueAt(rIndex, cIndex); System.out.println("Value = "+ob); JScrollPane scrollPane = new JScrollPane(table); panel.add(scrollPane); frame.add(panel); frame.setSize(600,400); frame.setUndecorated(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getRootPane().setWindowDecorationStyle(JRootPane.COLOR_CHOOSER_DIALOG); frame.setVisible(true); } }
