android - Overriding equals funct in ArraySet -

how can achieve without getting

error: cannot inherit final arrayset

arrayset<myobject>objectlist = new arrayset<myobject>(){     @override     public boolean equals(object object) {         return ((myobject)this).getid()==((myobject)object ).getid();     } }; 

arrayset final class, meaning can't inherit it. trying create anonymous subclass when write

arrayset<myobject>objectlist = new arrayset<myobject>(){     @override     public boolean equals(object object) {         return ((myobject)this).getid()==((myobject)object ).getid();     } }; 

what want implement equals (and hashcode) myobject:

public class myobject {     ...     @override     public boolean equals(object other) {         if (other instanceof myobject) {             return getid() == ((myobject) other).getid();         }         return false;     } } 

then, arrayset work intend
