Having trouble calling method from another class. The program either won't compile or returns a null value

Question

This is how I am calling the method in MovieRatingApp class.

    movie1.getRatingDesc()

This is the getRatingDesc() method in the Movie class.

public String getRatingDesc(int reviewNum)
{
    String s = "";

    switch (reviewNum) 
    {
        case 1: 
            s = "Terrible";
            break;
        case 2: 
            s = "Bad";
            break;
        case 3:
            s = "Ok";
            break;
        case 4:
            s = "Good";
            break;
        case 5:
            s = "Great";
            break;
    }
    return s;
}

Every time I try to call the method I get an error: method getRatingDesc() from class Movie cannot be applied to given types.

When I change how I call my method to, movie1.getRatingDesc(int numReview) I get a different error. But what I really want to do is return the value of the variable "s" which describes the rating.

Answer 1

Just pass in the variable in your call.

int numReview; //declare numReview.
Scanner sc = new Scanner(System.in); //Assuming you're going to have the user type it in.
numReview = sc.nextInt(); //Accept next integer from console, store in variable.
System.out.println(movie1.getRatingDesc(numReview)); //Call it, print result.

Note that error handling is omitted. If somebody tries to enter text or a number that is unexpected, you'll need to be responsible for how that's treated.
