    Default How to display numbers with leading zeros

    This program displays numbers with leading zeros.

    Java Code:
    public class number {
    
     	public static void main(String args[]) {
     		long n = 123456789;
     		String mask = "00000000000000";
     		String ds = Long.toString(n); 
    
                    // double to string
     	        String z = mask.substring(0 , mask.length() - ds.length()) + ds;
     	        System.out.println(z);
           }
    }

    Default

    This one too.

    Java Code:
    public class Number {
    public static void main(String args[]) {
        long n = 123456789;
        String f = "%014d";
        String z = String.format(f, n);
        System.out.println(z);
      }
    }
