Compare objects in LinkedList.contains()

Question

I want to be able to have LinkedList.contains() return true for a custom comparator.

Suppose that I have 1 LinkedList and 2 objects

LinkedList

        

Answer 1

The contains() method uses equals() to determine whether an object is in the list. I suspect your class MyObject does not override the equals() method, and this will be why myList.contains(b) is returning false.
