public class MainClass {
  public static void main (String [] args) {
     MyClass one = new MyClass(8);
     MyClass two = new MyClass(8);
     if (one.equals(two)) {
        System.out.println("one and two are equal");
     }
  }
}
class MyClass {
  private int moofValue;
  MyClass(int val) {
     moofValue = val;
  }
  public int getMyClassValue() {
     return moofValue;
  }
  public boolean equals(Object o) {
    if ((o instanceof MyClass) && (((MyClass)o).getMyClassValue()
         == this.moofValue)) {
      return true;
    } else {
       return false;
    }
  }
}

one and two are equal
