How to return multiple string values from a method java [duplicate]

Question

I am unable to return both username and pass String values at the same time.

    public static String executeLogin(String username, String pass) {
        int totalAttempts = 5;

        if (totalAttempts != 0) {
            if (username == "Javaprogram" && (pass == "Legend1@")) {
                System.out.println("Correct");
            } else {
                System.out.println("Incorrect Login");
                totalAttempts--;
            }
            if (totalAttempts == 0) {
                System.out.println("Maximum number of attempts exceeded");  
            }

        }
        return "username,pass";                 
    }

Unrelated to your question, that's not how you compare strings in java. — azurefrog

You cannot return multiple values with a single method (unless the method is called multiple times). — user11837869

That's not possible with java. Create an object instead (let's say Credentials) that holds both values and return an instance of said object. — jSebestyén

Also I can't think of any logical reason you would want to return username and pass...you are passing them into the method... thus you already have them in the caller? — RobOhRob

Note: you should have your 'total attempts' variable outside the scope of the function!

You can return a list of strings:

static int totalAttempts = 5;

public static String[] executeLogin(String username, String pass) {

    if (totalAttempts != 0) {
        if (username == "Javaprogram" && (pass == "Legend1@")) {
            System.out.println("Correct");
        } else {
            System.out.println("Incorrect Login");
            totalAttempts--;
        }
        if (totalAttempts == 0) {
            System.out.println("Maximum number of attempts exceeded");
        }

    }

    return new String[]{username, pass};
}

Why not just make a Credentials class and go the OOP way. Otherwise the user has to deal with how big the array actually is, maybe its empty or just one or three entries, who knows. It is just error prone.
