Different ways to format long with Java System.out.format

The System.out.format is used in Java to format output. Here, let's say the following is our long.

long val = 787890;

To format, we have considered the following that justifies the output.

System.out.format("%d%n", val);
System.out.format("%9d%n", val);
System.out.format("%+9d%n", val);
System.out.format("%08d%n", val);
System.out.format("%,9d%n", val);

The following is the complete example that displays the difference in output as well.

Example

Live Demo

import java.util.Locale;
public class Demo {
   public static void main(String []args) {
      long val = 787890;
      System.out.format("%d%n", val);
      System.out.format("%9d%n", val);
      System.out.format("%+9d%n", val);
      System.out.format("%08d%n", val);
      System.out.format("%,9d%n", val);
   }
}

Here is the output. You can easily notice the differences in format.
