Correction:

public class MyClass1 {
   private final int value;

   public MyClass1(int value) {
       this.value = value;
   }

   public static int hashCode(MyClass1 obj) {
       return 3 * obj.value;
   }

   public static void main(String... args) {
       MyClass1 c = new MyClass1(99);
       System.out.println(c.hashCode());
       System.out.println(hashCode(c));
       System.out.println(Object.hashCode(c)); // compile error if using 
official version of class Object
   }
}
