Thread: Format Precision Exception? What's going on?

public class test {
    public static void main(String[] args) {
       double meter;
       double foot;
       double x = 1;
       double y = 20;
 
 
        System.out.println("Feet \t Meters \t | \t Meters \t Feet");
 
        while (x <= 10 && y <= 65){
            meter = footToMeter(x);
        foot = meterToFoot(y);
            System.out.printf("%10.1d \t %10.3d  | %10.1d \t %10.3d", x, meter, y, foot);
 
 
        x++;
        y += 5;
        }//end of while
 
    }//end of main method
 
    public static double footToMeter(double foot) {
 
        return 0.305 * foot;
    }//end of footToMeter
 
    public static double meterToFoot(double meter) {
 
       return 3.279 * meter;
    }//end of meterToFoot
 
 
 
}

it is something inside this part, but i can't figure out what is wrong:

System.out.printf("%10.1d \t %10.3d  | %10.1d \t %10.3d", x, meter, y, foot);

Use "%d" for ints and longs.
Use "%SomethingElse" for floats and doubles.

Formatter syntax

Thanks! Works perfect now. I figured d stood for double, good to know. I appreciate the fast and informative response!

d is for decimal because, in that case, we are dealing with formatting an int using its decimal (base 10) representation.
