Prior to Java SE 8, Java supported three programming paradigms. Java SE
8 adds ________.
a. procedural programming
b. object-oriented programming
c. generic programming
d. functional programming. - 🧠ANSWER ✔✔d. functional programming
The new language and library capabilities that support functional
programming were added to Java as part of Project ________.
a. Utilitarian
b. Upsilon
,c. Lambda
d. Utility - 🧠ANSWER ✔✔c. Lambda
Which of the following statements is false?
a. Prior to functional programming, you typically determined what you
wanted to accomplish, then specified the precise steps to accomplish that
task.
b. Using a loop to iterate over a collection of elements is known as external
iteration and requires accessing the elements sequentially. Such iteration
also requires mutable variables. External iteration is easier to parallelize.
c. Letting the library determine how to iterate over a collection of elements
is known as internal iteration.
d. Functional programming focuses on immutability—not modifying the data
source being processed or any other program state - 🧠ANSWER ✔✔b.
Using a loop to iterate over a collection of elements is known as external
iteration and requires accessing the elements sequentially. Such iteration
also requires mutable variables. External iteration is easier to parallelize.
Actually, internal iteration is easier to parallelize.
Which of the following statements is false?
,a. Functional interfaces are also known as single abstract method (SAM)
interfaces.
b. Package java.util.function contains six basic functional interfaces
BinaryOperator, Consumer, Function, Predicate, Supplier and
UnaryOperator.
c. There are many specialized versions of the six basic functional interfaces
for use with int, long and double primitive values. There are also generic
customizations of Consumer, Function and Predicate for binary
operations—that is, methods that take two arguments.
d. All of these statements are true - 🧠ANSWER ✔✔All of these statements
are true
The basic generic functional interface ________ in package
java.util.function contains method apply that takes two T arguments,
performs an operation on them (such as a calculation) and returns a value
of type T.
a. Consumer<T>
b. Function<T,R>
c. Supplier<T>

, d. BinaryOperator<T> - 🧠ANSWER ✔✔d. BinaryOperator<T>
The basic generic functional interface ________ in package
java.util.function contains method accept that takes a T argument and
returns void. Performs a task with its T argument, such as outputting the
object, invoking a method of the object, etc.
a. Consumer<T>
b. Function<T,R>
c. Supplier<T>
d. BinaryOperator<T> - 🧠ANSWER ✔✔a. Consumer<T>
The basic generic functional interface ________ in package
java.util.function contains method apply that takes a T argument and
returns a value of type R. Calls a method on the T argument and returns
that method's result.
a. Consumer<T>
b. Function<T,R>
c. Supplier<T>
d. BinaryOperator<T> - 🧠ANSWER ✔✔b. Function<T,R>
