Java Spring Desktop application with multiple classes and jframe

Hi i am developing a desktop java spring application..It has many Jframes forms and classes...How to close one Jframe from another..Please tell...

First jframe

package desktopapplication2; import java.awt.Graphics; import java.io.FileNotFoundException; import java.io.IOException; import java.lang.management.ManagementFactory; import com.sun.management.OperatingSystemMXBean; import com.sun.servicetag.SystemEnvironment; import java.io.BufferedReader; import java.io.File; import java.io.FileReader; import java.io.InputStream; import java.io.InputStreamReader; import java.util.StringTokenizer; import java.util.logging.Level; import java.util.logging.Logger;

public class NewJFrame1 extends javax.swing.JFrame {

/** Creates new form NewJFrame1 */
public NewJFrame1() {
    initComponents();
    GetSystemInfo();
     try {

        GetBiosInfo();
        GetMemInfo();
        GetCPUInfo();// TODO add your handling code here:
          } 
     catch (Exception ex) {
        Logger.getLogger(MainScreen.class.getName()).log(Level.SEVERE, null, ex);
    }
}

private void jLabel3MouseClicked(java.awt.event.MouseEvent evt) {

             Touchscreen t = new Touchscreen(); **---->This is not disposing Jframe2**
              t.dispo();

}

Second Jframe

package desktopapplication2;

import java.awt.Color; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.BufferedWriter; import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.Timer;

public class Touchscreen extends JFrame {

/** Creates new form Touchscreen */
public Touchscreen() {
    initComponents();
    jLabel2.setVisible(false);
    this.setTitle("Touchscreen Test");
    jLabel1.setText("Testing Touchscreen");
    deletefile();
   this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    tc.start();
}

public void Touchscreen_dispo() { dispose(); ---->Even though this function is called,this Jframe is not disposing or hiding.. }

}
