Java String to integer with leading zeros

The format() method of the String class is used to convert string to integer with leading zeros.

Example:

package com.w3schools360;

public class StringToInt {
  public static void main(String args[]){
      String str="000000575";
      /* String to int conversion with leading zeroes
       * the %06 format specifier is used to have 6 digits in
       * the number, this ensures the leading zeroes
       */
      str = String.format("%06d", Integer.parseInt(str));
      System.out.println("Output String: "+str);
  }
}

Output:

Output String: 000575
