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

- Your question is correct, the answer is "yes". But your example is syntactically incorrect and completely confusing.AlexR– AlexR2015-12-28 09:53:38 +00:00Commented Dec 28, 2015 at 9:53

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.
