Question
Consider a declaration of a generic method compute:
public static <T extends Comparable<T>> void compute(T[] data) { ... }
Which statement is true about a parameter supplied when calling this method?
The parameter can be any array holding elements of some class C, as long as C is
the parent of a class that implements the Comparable interface.
The parameter can be any array holding elements of some class C, as long as the
class C implements the Comparable interface.
The parameter can be any array holding elements of some class C since it is a
generic method.
The parameter can be any array holding elements of some class C, as long as the
class C implements the Comparable interface or C extends a class that
implements Comparable.
