JAVA help

Hey, the &d is not working in this program.... anyone know why?   I am new to java.

import java.util.Scanner;


public class Circle {
   

    public static void main( String args[] )
    {

    Scanner input = new Scanner( System.in );

    double radius;
    double diameter;
    double circum;
    double area;
   
    //Get Radius
    System.out.println( "Enter Radius:" );
    radius = input.nextInt();

    //Figure Values
    diameter = radius * 2;
    circum = 3.14159 * diameter;
    area = 3.14159 * radius * radius;

    System.out.printf( "Diameter is %d\n: " , diameter );
    }
}

OP here, I ment the %d is not working...

Your troll level is maximum.

OP..    Um...  when I go to run it, it stops at the %d and says a buncha error shit.  Does the code look right?

Probably a rounding error. Use Math.PI for greater accuracy.

mm, I just tried that.   Can a double variable be presented with the %d format?

This is the reason I come to /prog/, for the trolling and cheap laughs.

%d is for integers. You need to use %f.

I thought pi was much longer than that.

3.14159265358979 is how much of Math.PI I remember. Lol

in Java you don't use printf. ever. it's System.out.print or System.out.println

Also, you just put in the damn variable. System.out.print("The Diameter is " + diameter);

There, I killed the joke

The joke's on you:

http://java.sun.com/j2se/1.5.0/docs/api/java/io/PrintStream.html#printf(java.lang.String,%20java.lang.Object...)

But printf() isn't nearly as ENTERPRISE as using the + operator

Of the application Thanks.

I liked the atmosphere of couple first episodes very much, then there were many rather uninteresting plot developments but overall very feel giving and satisfying experience.

Teach a man to fish, and you just eliminated your customer base idiot. Their ignorance was your job security as a restaurant owner ! Now you have to face a foreclosure! Are you proud of yourself? Are you?
