Thread: Get value before execute printf in Java

Hello,

In my code, I have the below output. but I expected to execute the first printf then get two integers from the console.
(Run in Netbeans - Widnows 10)

import java.util.Scanner;
 
class square
{
    protected int height;
    protected int width;
    protected int surfaceArea;
 
    public square(){}
    public square(int h, int w)
    {
        height = h;
        width = w;
    }
 
    public void ComputeSurfaceArea()
    {
        surfaceArea =  height*width;
        System.out.printf("Square Area is: %d\t",surfaceArea);
    }
 
}
 
class cube extends square
{
    private int depth;
 
    public cube(int d)
    {
        depth = d;
    }
 
    @Override
        public void ComputeSurfaceArea()
    {
        surfaceArea =  6*(depth*depth);
        System.out.printf("Cube Area is: %d\t",surfaceArea);
    }
}
 
public class NewClass {
        public static void main(String[] args)
        {
            int w,h;
            Scanner sc = new Scanner(System.in);
 
            System.out.printf("\nWidth & Height: ");
            w = sc.nextInt();
            h = sc.nextInt();
 
             square mySquare = new square(w,h);
             mySquare.ComputeSurfaceArea();
 
             System.out.printf("\nCube: ");
             int d = sc.nextInt();
             cube myCube = new cube(d);
             myCube.ComputeSurfaceArea();
        }
}

Width & Height: Square Area is: 6
8
Cube: Cube Area is: 384

Can you explain what the problem is?

Why are you using printf instead of print or println?
