Java Program to Match Zip Codes
Let’s say we have the following zip code.
String zipStr = "12345";
Now, set the following regular expression to match zip codes in America.
String reg = "^[0-9]{5}(?:-[0-9]{4})?$";
Example
public class Demo { public static void main(String[] args) { String zipStr = "12345"; // regular expression String reg = "^[0-9]{5}(?:-[0-9]{4})?$"; boolean res = zipStr.matches(reg); System.out.println("Is it a valid zip code in US? "+res); } }
Output
Is it a valid zip code in US? True
