Java Method with generic class as argument

Question

It is possible write a method in java with generic class with argumet??

example:

public void Transfer (class c){
    class.Search();
}

Answer 1

Yes, you would need to do something like so:

public class Foo<T> {
    public void Transfer(T c) {
        c.Search();
    }
}

Since you seem to want to invoke a specific method, you might want to define an interface which provides the methods you are after, and bind the generic constraint with it:

public interface MyInt {
    void Search();
}

....
public class Foo<T extends MyInt> {
    public void Transfer(T c) {
        c.Search();
    }
}

Alternatively:

public class Foo {
    public void Transfer(MyInt c) {
        c.Search();
    }
}

The last example does away with generics and uses interfaces, which can sometimes yield code which is easier to follow, depending on what you are trying to achieve.
