Question

I hava a generic class called ArrayBag. I want to override equals method. So i wrote

public boolean equals(T other){

} // gives error

error message: Name clash: The method equals(T) of type ArrayBag has the same erasure as equals(Object) of type Object but does not
override it

Answer 1

The equals method you are trying to override expects an Object. When your code is translated to byte code, type erasure transforms your T into an Object, which conflicts with the existing equals method.

@Override
public boolean equals(Object other) {
    if (other instanceof T)
    {
        T o = (T) other;
        ...
    }
}

Inside the method you can handle casting to T.
