Question

I’m new to Java and I’m not sure if I even ask this question right.
I have two voids, in the second one I get my string and I want to use it my main void.
The code is something like that:

public void onCreate(Bundle savedInstanceState) {
 shuffle();
 //Here I want to use the string correctAnswer
}
public void shuffle() {
 String correctAnswer = "whatever";
}

Answer 1

If you want to use the String calculated in the second function, why use void?

public void onCreate(Bundle savedInstanceState) {
    String s = shuffle();
    //Use s;
}

public String shuffle() {
    String correctAnswer = "whatever";
    return correctAnswer;
}

You could also make correctAnswer an instance variable:

private String correctAnswer;

public void onCreate(Bundle savedInstanceState) {
    shuffle();
    //Use instance variable correctAnswer;
}

public void shuffle() {
    correctAnswer = "whatever";
}
