Temperature conversion not working can someone help me.

Question

import java.awt.Graphics; // program uses class Graphics
import javax.swing.JApplet; // program uses class JApplet
import javax.swing.JOptionPane;
public class Temp1 extends JApplet
// draw text on applet's background
public void paint( Graphics g )
// call superclass version of method paint
super.paint( g );
int cels;
for (int fahr = 0; fahr <= 212; fahr++ )
cels = 5.0 / 9.0 * (fahr - 32);
System.out.printf( "%df\n", cels);
g.drawString( "Is then converted to" + cels + "degrees Celsius", 25, 25 );
} // end method paint
} // end class WelcomeApplet
it does give me one error its says possible loss of precision on line 15, the cels = 5.0 / 9.0 * (fahr - 32); line

Answer 1

You're basically doing this:
int i = 1.5;Obviously, you can't put 1.5 into an int, so it will get truncated down to 1. However, the compiler is forcing you to either fix it or tell it that you really want to truncate the double to an int.
double d = 1.5;
OR
int i = (int)1.5;
