Missing return statement in for loop

Question

I have a for loop that returns values from an array.

public static String getPieces(){
        for(int y=0; y<=7; y++)
            for(int x         


        

Answer 1

Besides the loop being completely pointless (because it will return piece[0][0]), adding an extra return line might help you:

public static String getPieces(){
        for(int y=0; y<=7; y++){
            for(int x=0; x<=7; x++){
                return piece[x][y];
            }
        }

}

Since you stated that you want to return 64 values, you'll have to return an array. 

public static ArrayList getPieces(){
    ArrayList strings = new ArrayList();
    for(int y = 0; y <= 7; y++){
        for(int x = 0; x <= 7; x++){
            strings.add(piece[x][y]);
        }
    }
    return strings;
}
