How can I pass variable's from one frame to other

Question

//This is the first frame where the value in the TextField
//tf1 and tf2 are to be passed to 2nd Frame
import java.awt.*;
import java.awt.event.*;
public class del extends Frame implements ItemListener,ActionListener
public Panel p,p1,p2;
public Button b,n;
public Label l1,l2;
public TextField tf1,tf2;
public del()
setLayout(new FlowLayout(FlowLayout.LEFT));
Panel p=new Panel();
n=new Button("Submit");
p.add(n);
add(p);
l1=new Label(" Enter the Temperature : ");
tf1=new TextField(5);
p.add(l1);
p.add(tf1);
add("South",p);
l2=new Label(" Enter the Compund ");
tf2=new TextField("N-OCTANE",15);
p1=new Panel();
p1.add(l2);
p1.add(tf2);
add("South",p1);
setSize(600,700);
setVisible(true);
public void itemStateChanged(ItemEvent ie)
repaint();
public void actionPerformed(ActionEvent a)
if(a.getSource()==n)
this.setVisible(false);
new Finalput1();
repaint();
public static void main(String[]args)
del d=new del();
//2nd Frame which will appear on clicking submit button
import java.awt.*;
class del1 extends Frame
public static double T;//value in 1st text field has to be stored in variable T
String compd=" ";//value in 2nd textField has to be stored in this string
TextField tf;
public del1()
setLayout(new FlowLayout());
setSize(800,700);
setVisible(true);
public void paint(Graphics g)
g.drawString(" INPUT DATA : - ",30,120);
g.setColor(Color.black);
g.drawString(" Component Name ="+compd,20,160);
g.drawString(" Temperature of the Mixture ="+T,30,250);
public static void main(String[]args)
new del1();
Pls help me.
I will be happy if anyone help's me!

Both your classes seem to be independent applications. (they are public, and they have their public static void main)
Is this your intention? If so, your question is how to pass data from one application to another. That can be done in many ways, and it is a complicated issue. (if one application wants to pass data to another, you first have to find the other one, and if it isnt running you might want to start... - lots of things to think about.)
If what you want to do is simply to pass data from one Frame to another, the matter is quite more simple.
Here is a sample:
import java.awt.event.*;
import java.awt.*;
public class F1 extends Frame implements ActionListener
private F2 theOtherFrame;
public F1()
Button b;
b=new Button("Action");
b.addActionListener(this);
add(b);
setSize(100,100);
setVisible(true);
public void actionPerformed(ActionEvent e)
if (theOtherFrame == null)
     theOtherFrame = new F2();
     theOtherFrame.setSize(100, 100);
theOtherFrame.setSomeData("Her you have som data");
theOtherFrame.setVisible(true);
public static void main(String[] args)
new F1();
class F2 extends Frame
private String strData;
private Label lab;
public void setSomeData(String str)
lab.setText(str);
repaint();
public F2()
lab = new Label();
add(lab);
