How to use a variable produced in a method in other methods?

Question

Basically, i need to use the value of spaces from this method spacesCount in another method, or in the main void run. But it won\'t let me use outside?

Answer 1

You are providing the value of spaces as the return value from the method. So you need to store the result in a variable and use it in your other method:

public static void main(String args[]) {
    String myString = "this is a test";

    int spaces = spacesCount(myString);
    // use spaces to do something
}
