Question

Which of these is an correct way of defining generic method?

(a) <T1, T2, …, Tn> name(T1, T2, …, Tn) { /* … */ }

(b) public <T1, T2, …, Tn> name<T1, T2, …, Tn> { /* … */ }

(c) class <T1, T2, …, Tn> name[T1, T2, …, Tn] { /* … */ }

(d) <T1, T2, …, Tn> name{T1, T2, …, Tn} { /* … */ }

I have been asked this question in an internship interview.

The question is from Generic Methods topic in portion Generics of Java

Answer 1

The correct option is (b) public <T1, T2, …, Tn> name<T1, T2, …, Tn> { /* … */ }

The explanation is: The syntax for a generic method includes a type parameter, inside angle brackets, and appears before the method’s return type. For static generic methods, the type parameter section must appear before the method’s return type.
