Question: Write a Java program that asks the user to input a string and checks if it's a valid gift card code according to these rules:
Write a Java program that asks the user to input a string and checks if it's a valid gift card code according to these rules:
The gift card code must be exactly characters long.
The first three characters must be uppercase letters.
The fourth character must be a hyphen
The last four characters must be digits.
Your program should use two methods:
isValidGiftCardCodeString code: This method takes a string as input and returns true if the code is valid according to the rules above, and false otherwise. This method should use if conditions and the substring method to check the gift card code rules. You might also find Character.isUpperCase and Character.isDigit helpful.
printResultboolean isValid: This method takes a boolean value as input. If the input is true, it prints "Valid Gift Card Code". If the input is false, it prints "Invalid Gift Card Code".
Your main program should use a dowhile loop to repeatedly ask the user for a gift card code until a valid one is entered. Inside the loop, the program should call the isValidGiftCardCode method to check the entered code and the printResult method to display the result.
Example Usage:
Enter a gift card code: ABC
Valid Gift Card Code
Enter a gift card code: abc
Invalid Gift Card Code
Enter a gift card code: ABCD
Invalid Gift Card Code
Enter a gift card code: ABC
Invalid Gift Card Code
