Java Program to Check Whether a Date is Valid or Not

In this tutorial, we are going to see how to write a java program to check whether a date is valid or not by handling the ParseException.
 

Java Program to Check Whether a Date is Valid or Not:

import java.text.*;
import java.util.*;

public class Main {
   public static boolean check(String date)
   {
	    // Set the preferred date format
	    SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy");
	    format.setLenient(false);
	    try
	    {
	        Date d = format.parse(date); 
	        System.out.println(date+" is a valid date");
	    }
	    // Invalid date
	    catch (ParseException e)
	    {
	        System.out.println(date+" is an invalid date");
	        return false;
	    }
	    // Returns true if the date is valid
	    return true;
   }
   
   public static void main(String args[]){
		check("07/25/2020");
		check("07/25/0000");
		check("07,25,2020");
   }
}

Output:

07/25/2020 is a valid date
07/25/0000 is an invalid date
07,25,2020 is an invalid date
