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
