Adding text to java frame

Can you be more specific?

If by "adding text" you mean drawing a String of text on the screen, that can be done by drawing to the current graphics state of the frame. You can get that by using the getGraphics() method. Then, you can draw to that:

Graphics g = getGraphics();
g.drawString("this is a test", 0, 0);

So first, we are passing a reference of the current graphics state to a variable g. Then, we are drawing a String to that reference using the drawString(String, int, int) method from the Graphics class. The first argument is a String, which will be the String that you want drawn on the frame. The next two are the coordinates, the first one being x, the second y.

So the above code simply draws "this is a test" at coordinates (0, 0). Note that the above can be simplified to getGraphics().drawString("this is a test", 0, 0);.

You also might be referring to adding a text box or text area to the field, then setting the text value of that.

Again, please be more specific.

Well, setting the text value of a label can be done in it's constructor. Then you just add it to the frame.

Label label = new Label("text");
frame.getContentPane().add(label);

This is what i have right now ... please correct me where i am wrong ... i am only a beginner... only the last calculation is being displayed

import java.awt.*;
import java.awt.event.*;
import javax.swing.JOptionPane;

public class test extends Frame
{
public static void main(String[] args)
{
Frame f = new Frame("Banners Results");
f.addWindowListener
(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
}
);

f.setSize(500,700);
//f.setLocation(10,10);
f.setVisible(true);

String Test;
int number;

Test = JOptionPane.showInputDialog("Enter no: ");
number = Integer.parseInt(Test);

f.add(new Label(number + " "));

double number1 = number * 500;

f.add(new Label((int)number1+ " "));

double number2 = number1 * 0.3;

f.add(new Label((int)number2+ " ")); //THIS LINE COMES UP ON THE FRAME .... THe lines above this don't display

}

}
