State whether each of the following is true or false. If false, explain why.

a) An intermediate operation specifies tasks to perform on the stream’s elements; this is efficient because it avoids creating a new stream.

b) Reduction operations take all values in the stream and turn them into a new stream.

c) If you need an ordered sequence of int values, you can create an IntStream containing such values with IntStream methods range and rangeClosed. Both methods take two int arguments representing the range of values. Method rangeClosed produces a se- quence of values from its first argument up to, but not including, its second argument. Method range produces a sequence of values including both of its arguments.

d) Class Files (package java.nio.file) is one of many classes throughout the Java APIs that have been enhanced to support Streams.

e) Interface Map does not contain any methods that return Streams.

f) The Function interface has methods apply (abstract), compose (abstract), andThen (default) and identity (static).

g) If one class inherits the same default method from two interfaces, the class must over- ride that method; otherwise, the compiler does not know which method to use, so it generates a compilation error.
