How to access jtable cells in multiple tabs?

Question

Hi,
in my program when I push a button 3 tabs are created. And all these tabs have a table in it. What I want to do is that When I push other button I want to access all these tables and cells. and get the cell values. How can I get the value of one cell in the jtable when I have multiple tabs?
thanks in advance.

Answer 1

This is my main window
public class AuditClient extends javax.swing.JFrame {
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                        
createCheckList();
public void createCheckList() {
CheckList.createCheckList(CheckListChildPane);
private javax.swing.JTabbedPane CheckListChildPane;
private javax.swing.JPanel CheckListParentPanel;
And This is the CheckList.java : This code create tabs and tables in it. (from xml file).
public class CheckList extends JPanel implements ActionListener{
JTable table;
public CheckList(Object[][] TheData) {
MyTableModel model = new MyTableModel();
model.setData(TheData);
table = new JTable(model);
JScrollPane scrollPane = new JScrollPane(table);
add(scrollPane);
class MyTableModel extends AbstractTableModel {
public String[] columnNames = null;
public Object[][] data = null;
public final Object[] longValues = null;
public void setColumnNames(String[] cols) {
this.columnNames=cols;
public void setData(Object[][] datas) {
this.data=datas;
public int getColumnCount() {
return columnNames.length;
public int getRowCount() {
return data.length;
public String getColumnName(int col) {
return columnNames[col];
public Object getValueAt(int row, int col) {
return data[row][col];
public Class getColumnClass(int c) {
return getValueAt(0, c).getClass();
public static void createCheckList(JTabbedPane CheckListChildPane) {
//creates tabs and tables in it
I want to access the tables (which I created in CheckList java) from my main window. I want to get the cell values of these tables
thanks
