Introduction

Date validation in Java is vital for applications that handle scheduling, data logging, or require date input verification. Java's java.util.regex package allows for regex-based date validation.

What is Date Regex?

Java regex for date validation ensures adherence to a specific date format, like YYYY-MM-DD.

The Date Regex Pattern

  • Pattern for YYYY-MM-DD: ^\\d{4}-\\d{2}-\\d{2}$

  • This pattern matches dates in the "YYYY-MM-DD" format.

How to Validate Dates in Java?

To validate dates in Java:

import java.util.regex.*;
public class DateValidator {
    public static boolean isValidDate(String date) {
        String regex = "^\\d{4}-\\d{2}-\\d{2}$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(date);
        return matcher.matches();
    }
    public static void main(String[] args) {
        String date = "2024-01-29";
        System.out.println("Is date valid? " + isValidDate(date));
    }
}

Uses of Date Regex Validation

  1. User Input Validation: Verifying date formats in user interfaces and forms.

  2. Data Consistency: Ensuring standard date formats in databases and during data exchange.
