Thread: Returning value from method? Arrays-

Hello everyone,

Here is the problem that I am trying to solve: Write a method that is passed two arrays. Your method should return true if the two arrays have the same size and the same contents. Otherwise, return false.


I am receiving the following error in BlueJ - ".class expected" on this line:

System.out.println(f(int[] a, int[] b));    // print out the value returned by f

Any help would be appreciated very much.



Here is what I have completed so far:

 
class Num2
{
    public static void main (String[] args)
    {
        int[] a = {3, 4, 5, 6, 7};
        int[] b = {5, 8, 9, 10, 5};
        f(a, b);                  // call the f method
        System.out.println(f(int[] a, int[] b));    // print out the value returned by f
    }
 
    public static boolean f(int[] a, int[] b)
    {
        if (a.length == b.length)
        {
            for (int i = 0; i < a.length; i++)
            {
                if (a[i] != b[i])
                return false;
 
            }
            return true;
               }
 
        else
        return false;
 
         } 
 
}

It thinks you're referring to a class or something. Java has array params in method calls the same way everything else is put in a method call (i.e. with only the variable name, the array param syntax is only need in the params to the actual method body, not the method call)).

Thank you! That makes sense. I had no idea what I was doing wrong.
