Java file cannot access methods even though class file is in same directory
<p>I was given only a .class file for homework and need to write a program that accesses its methods. Well, I have the .class file in the same directory, but I cannot access its methods, so my program won't compile! I've tried on JGrasp and Eclipse. Both 'cannot find symbol' (the method name).</p>

<p>I am absolutely positive that I am using the right method names. Why isn't it working?? </p>

<p>This is my code in Hw.java</p>

<pre><code>public class Hw {

    public static void main(String[] args) 
    {
     int[] a1 = {1, 2, 3, 4, 5};
        int[] a2 = {5, 4, 3, 2, 1};
        int[] a3 = {1};
        int[] a4 = {2, 5, 3, 1, 4};
        int[] a5 = {1, 2, 1};

        System.out.println(sortA(a1));        
        System.out.println(sortA(a2));
        System.out.println(sortA(a3));
        System.out.println(sortA(a4));
        System.out.println(sortA(a5));        
  }
}
</code></pre>

<p>And the error I'm getting in JGrasp:</p>

<p>Hw.java:11: error: cannot find symbol
            System.out.println(sortA(a1));<br>
                               ^
  symbol:   method sortA(int[])
  location: class Hw</p>
