[CSC 204] Formatting Integer Output

[Andrew J. Pounds]

Here is some code demonstrates how to use the printf command to format 
integers -- feel free to use this in your code if you have not already 
done something else...


public class FormatOutput{

   public static void main(String args[]){

       // Examples of formatting integers using printf

       int a = 2;
       int b = 10;
       int c = 120;

       // Use 3 spaces for the number
       System.out.printf("The number is %3d\n", a);
       System.out.printf("The number is %3d\n", b);
       System.out.printf("The number is %3d\n", c);

       // Use 4 spaces for the number
       System.out.printf("The number is %4d\n", a);
       System.out.printf("The number is %4d\n", b);
       System.out.printf("The number is %4d\n", c);

       // Use 8 spaces for the number
       System.out.printf("The number is %8d\n", a);
       System.out.printf("The number is %8d\n", b);
       System.out.printf("The number is %8d\n", c);

       // The \n above does the same thing as System.out.println()
   }
}
