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.

Answer 1

You can cast it inside the method, just make sure that is of the right type using instance of

if(obj instanceof Person)
{
   Person otherPerson = (Person) obj;
   //Rest of the code to check equality
}
else
{
//return false maybe
}
