Possible to return a String array

Question

Is it possible to make a method that returns a String[] in java?

Answer 1

Yes, but in Java the type is String[], not string[]. The case is important.

For example a method could look something like this:

public String[] foo() {
    // ...
}

Here is a complete example:

public class Program
{
    public static void main(String[] args) {
        Program program = new Program();
        String[] greeting = program.getGreeting();
        for (String word: greeting) {
            System.out.println(word);
        }
    }

    public String[] getGreeting() {
        return new String[] { "hello", "world" };
    }
}

Result:

hello
world
