5,509 Pointspublic override string Equals(object obj1 , object obj2){} won't compile. Why?
using System; namespace Treehouse.CodeChallenges { public class VocabularyWord { public string Word { get; private set; }
public VocabularyWord(string word)
{
Word = word;
}
public override string ToString()
{
return Word;
}
public overide bool Equals(object obj1,object obj2)
{
if(obj1.Word == obj2.Word)
{
return true;
}
else
{
return false;
}
}
}
}
Is there something wrong with obj1.Word and obj2.Word?
using System;
namespace Treehouse.CodeChallenges
{
public class VocabularyWord
{
public string Word { get; private set; }
public VocabularyWord(string word)
{
Word = word;
}
public override string ToString()
{
return Word;
}
public overide bool Equals(object obj1,object obj2)
{
if(obj1.Word == obj2.Word)
{
return true;
}
else
{
return false;
}
}
}
}

230,688 PointsThere are a few issues:
- as Patrik pointed out, "override" has 2 "r"s
- the override must have the same signature as the original function (which takes just one argument)
- an "object" doesn't have a "Word" property, so you'll need to cast it to the right type
- you still need to accommodate the possibility of the argument being null
