Method accepting two different types as parameter

Question

I am writing a method that should accept as its parameter an object of one of two types which do not share a parent type other than Object. For example, the types are Dreams

Answer 1

Simply use method overloading.

public void utterlyDestroy(Dreams parameter) {
    parameter.crush();
}

public void utterlyDestroy(Garlic parameter) {
    parameter.crush();
}

If you want to support more than these two types in the same way, you can define a common interface for them all and use generics.
