EqualsBuilder vs own equals method

Question

I just came across a code using EqualsBuilder() in equals method. Is there any advantage of using it instead of writing (or generating from eclipse

Answer 1

Using ANYTHING except for your own implementation in equals() is GUARANTEED to be "worse" if you can use ... say a strictly unique ID.

If your ID is really unique you will most likely have the best, possible implementation with this, of course it needs to be polished quite a bit:

@Override
public boolean equals(Object other)
{
   if(other instanceof MyClass)
   {
      MyClass obj = (MyClass)other;
      return obj.getID() == this.getID();
   }
   else
      return false;
}

Have a look at this, this and especially this
