generics - Java override Object equals() method

Question

How do I override the equals method in the object class?

i.e I have

class Person{

//need to override here
public boolean equals (Object obj){

}

I want to convert the parameter obj to a type Person, but if I do (Person) obj it won't work.

It's actually more complicated than you might think. Have Eclipse (or whatever IDE you're using) auto-generate an equals method; you'll see it contains a few checks and casts before it does a comparison.
