How can I stop a program until a button will be clicked

Question

I have a class that create a JTable and in this class I have two columns, the first culumns has the name of the variables an the second column has a checkbox to select the correponding variable.this JTable is created from a vector originating in other class. I need obtain a vector of integers with the number of the variable selected after the JButton will be clicked. For this i create a method called EspererSeleccion. This is the class
import javax.swing.table.AbstractTableModel;
import java.awt.*;
import java.awt.event.*;
import javax.swing.table.TableColumn;
import javax.swing.border.Border;
import java.util.*;
import javax.swing.*;
import java.lang.Integer;
public class MiTabla extends JFrame implements ActionListener
//Variables de Instancia
private boolean DEBUG = true;
public boolean TERMINA=false;
public Vector Valores=new Vector(1,1);
//Constructor de objetos de la clase MiTabla
public MiTabla()
super("Variables");
Border empty;
MiModelodeTabla myModel = new MiModelodeTabla();
JTable table = new JTable(myModel);
table.setPreferredScrollableViewportSize(new Dimension(300, 200));
TableColumn column=null;
column = table.getColumnModel().getColumn(0);
column.setPreferredWidth(220);
column = table.getColumnModel().getColumn(1);
column.setPreferredWidth(80);
//Crea el scroll pane y agrega la tabla en el.
JScrollPane scrollPane = new JScrollPane(table);
empty= BorderFactory.createEmptyBorder();
JButton boton=new JButton("Aceptar Seleccion");
boton.setBorder(empty);
boton.addActionListener(this);
getContentPane().setLayout(new BorderLayout(100,0));
getContentPane().add(scrollPane, BorderLayout.CENTER);
getContentPane().add(boton, BorderLayout.SOUTH);
addWindowListener(new WindowAdapter()
public void windowClosing(WindowEvent e)
setDefaultCloseOperation(HIDE_ON_CLOSE);
dispose();
//System.exit(0);
//clase MiModelodetabla
class MiModelodeTabla extends AbstractTableModel
MiVector v=llamaVector();
int numElementos=v.size();
private int i,j;
public final Object[][] data=new Object[numElementos][2];
final String[] columnNames = {"Variable",
"Seleccion"};
public MiModelodeTabla()
CreaListas();
public void CreaListas()
for (i=0; i<numElementos; i++)
data[0]=v.elementAt(i);
for (j=0; j<numElementos; j++)
data[j][1]=new Boolean(false);
public MiVector llamaVector()
MiVector V1=new MiVector();
v=V1.addElementos();
return(v);
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 boolean isCellEditable(int row, int col)
if (col < 1)
return false;
else
return true;
public void setValueAt(Object value, int row, int col)
data[row][col] = value;
fireTableCellUpdated(row, col);
if (DEBUG)
String s=new String("true");
Integer I=new Integer(row);
String S=value.toString();
if(s.equals(S))
Valores.addElement(I);
else
Valores.remove(I);
value=(Object)value;
public void EsperarSeleccion()
while (TERMINA==false)
int i=0;
TERMINA=false;
public void actionPerformed(ActionEvent e)
TERMINA=true;
dispose();
and this is the method that create the JTable but when i call the method EsperarSeleccion the program fail and the JTable is not visible only the frame that contains It.
How can I do to stop the program or the actions until the JButton will be clicked using and other method diferent from the EsperarSelection method
Vector leeVariablesRelevantes ()
System.out.println ("Variables relevantes");
MiTabla frame = new MiTabla();
frame.pack();
frame.setVisible(true);System.out.println("El vector tiene "+frame.Valores.size()+" elementos");
int i;
for (i=0; i<frame.Valores.size(); i++)
System.out.println("El elemento "+i+" de el Vector es: "+frame.Valores.elementAt(i));
System.out.println();
return frame.Valores;

Answer 1

Say,Class A contains JTable and in Class B you wish to acess the vector which contains the things required by you.
First you have to get the reference of Class B in Class A.
It can be done in the following way.
In Class B ,you create a static method like this.
public static ClassB getObject()
  return this;
}Now you can get the Class B's object easily via this method.
Again in Class B , you write a method which will handle your requirment.(Let this method name be doThings( Vector vector))
Now in Class A's actionPerformed() ,when the buton is pressed ,just call doThings() and pass the vector.
