Java generics - compiler error

Question

What's wrong with this method definition?

public static List<T extends MyObject> T find() {

}

Compiler says:

Syntax error, insert ";" to complete MethodDeclaration

Is your class generic ? if not you must delare the method like this: public static <T> List<T extends MyObject> T find() — ortis

You have two return types there.

If you wanted to introduce a generic type T that would be

 public static <T extends MyObject>  List<T> find() {}

The proper method declaration would be:

public static <T extends MyObject> List<T> find() { ... }

When creating (static) generic methods, the generic parameter(s) has to be defined before the return-type, because they may be used in the return-type.
