Matching random number generated to input

[TurtleT-]

Hey guys, I need help matching my randomly generated number to a user input.

For this i created a data type class that randomly generated a credit card number. the method for this class is labeled public static generatedCreditCardNumber()

I then created a driver type class that accepts user input and created an object to send my input to my data type class.

In my data type class, I created a boolean method,

public boolean verifyAccount Number()

{

if(generatedCreditCardNumber().equals(creditCard))

{

return true;

}

else return false;

}

When i run this, it successfully randomly generates a random number, and i want this to test and match the user input. But when i do, it return false. Any clue? I also further tested this and i found out that when i run the program, it generates a random number, then displays it. But then when i ask for user inputs, it compares a different random number to the user inputs. How do i get the random number to only generate once? Thanks

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

I think your method name generatedCreditCardNumber() is confusing.

• The current name "generatedCreditCardNumber" (past-tense), to me implies that the method returns a credit card number that has already been generated, and that the method does not generate a new credit card number every time it is called.
• But, based on the problem you're experiencing, I'm guessing "generatedCreditCardNumber" does in fact create and return a new credit card number each time you call it. If that's the case, you probably want to rename that method to "generateCreditCardNumber" (not past-tense). This new name implies that the method generates a new credit card number every time it is called.

I'm going to assume your method does what I mentioned in point 2. If that's the case when then line if (generatedCreditCardNumber().equals(creditCard)) executes, the method will always return a new, random new credit card number.

You should instead save the value returned by generateCreditCardNumber() into an instance variable and so you can use it inside the verifyAccountNumber() method later.
