What do I write instead of "TheClass" to make this work? Or is there an alternative way to do it (possibly without making WithName and WithAge generic)?
class Item {
NeigborList<TheClass> neighbors;
}
class WithName extends Item { // here I want neighbors to be a NeighborList<WithName>
String name;
void someMethod() {
System.out.println(neighbors.nearestTo(this).name);
}
}
class WithAge extends Item { // here I want neighbors to be a NeighborList<WithAge>
int age;
void someOtherMethod() {
System.out.println(neighbors.nearestTo(this).age);
}
}
