Using Real Numbers

In this example the conversion of inches to centimeters requires a result with a decimal place. To allow this the variable holding the centimeters is declared as a double.

import java.awt.*;
import java.applet.Applet;
public class Converter extends Applet
{

int inches;
double centimeters;
public void init()
{

inches = 12;
centimeters = inches * 2.54;

}
public void paint(Graphics g)
{

g.drawString(inches + " inches = " + centimeters + " centimeters", 50, 50);

}

}

This is the output
