Q3) Write a program that reads a string from the keyboard and tests whether it contains a valid date. Display the date and a message that indicates whether it is valid. If it is not valid, also display a message explaining why it is not valid. The input date will have the format dd/mm/yyyy. A valid month value mm must be from 1 to 12 (January is 1). The day value dd must be from 1 to a value that is appropriate for the given month. September, April, June, and November each have 30 days. February has 28 days except for leap years when it has 29. The remaining months all have 31 days each. A leap year is any year that is divisible by 4 but not divisible by 100 unless it is also divisible by 400. Sample Input#1: Please enter a date to be checked: 05/04/2021 Sample Output#1: Your date was 05:04:2021 It is a valid date. Sample Input #2: Please enter a date to be checked: 32/03/2021 Sample Output #2: Your date was 32:03:2021 It isn’t a valid date.The reason it is invalid:The day value is greater than 31 in a month with just 31 days. Sample Input #3: Please enter a date to be checked: 30/02/2020 Sample Output #3: Your date was 30:02:2020. It isn’t a valid date.The reason it is invalid:The day value is greater than 29 in February in a leap year. Sample Input #4: Please enter a date to be checked: 29/02/2019 Sample Output #4: Your date was 29:02:2019. It isn’t a valid date.The reason it is invalid:The day value is greater than 28 in February in a non- leap year. Note: you should upload a java project file, otherwise will not be accepted.
