Advanced Programming: Functional Programming, Streams, and Object-Oriented Principles

Practice fill-in-the-blank flashcards reviewing core topics across Java Streams, Lambda Expressions, Object-Oriented Principles, and Functional Programming paradigms.

In Java, Stream was introduced in __________ to simplify the processing of collections and data using a functional approach.

Java 8

A Java Stream is not a data structure; operations that transform a stream into another stream and execute lazily are called __________ operations.

intermediate

In the Java Stream processing pipeline shown in the diagram, chained intermediate operations process input data until a(n) __________ triggers execution to produce the final output.

Terminal Operation

The intermediate stream operation __________ is used to flatten a stream of collections into a single stream of elements.

flatMap()

The intermediate method __________ performs an action on each element without modifying the stream and accepts a parameter of type Consumer.

peek()

The terminal method __________ reduces the elements of a stream to a single value by accepting a BinaryOperator parameter.

reduce()

Intermediate operations in Java Streams run based on the concept of __________, which ensures elements are processed one by one only when a terminal operation is invoked.

Lazy Evaluation

In Java, lambda expressions can access only variables from the enclosing scope that are final or __________.

effectively final

A functional interface in Java contains exactly __________ abstract method(s), but it may contain multiple default and static methods.

$$1$$

When defining a lambda expression with two or more input parameters, enclosing the parameters in __________ is mandatory.

parentheses ()

The built-in functional interface Predicate contains the abstract method boolean test(T t), whose purpose is to __________.

test a given condition and return true or false

The built-in functional interface Consumer defines the abstract method __________, which performs an action on a given argument without returning a result.

void accept(T t)

The lambda expression (int x, y) -> x + y is invalid because if one parameter specifies its type explicitly, then __________.

all parameters must specify their types

In the CS 4108 course assessment plan, the Theoretical and Practical Final Exam accounts for __________ of the total assessment score.

$$40\%$$

In object-oriented programming terminology, an action performed by an object (a verb) is defined as a(n) __________.

method

The OOP design principle also known as data hiding, where only an object's methods can modify information inside that object, is __________.

Encapsulation

The OOP design principle defined as the process of hiding implementation details and exposing only the functionality to the user is __________.

Abstraction

In the inheritance hierarchy diagram shown, the class acting as the common superclass for Automobile, Motorcycle, and Bus is __________.

Vehicle

According to object-oriented language classification, languages such as C++, Objective-C, and Object-Pascal are classified as __________ OO languages.

Hybrid

Developed by Alonzo Church, __________ is a minimal theoretical framework for studying computation through functions that forms the foundation of modern functional programming.

Lambda calculus

While object-oriented programming uses loops for iteration, functional programming languages implement iteration through __________.

recursion

A pure function has two main properties: it always produces the same output for the same arguments and has no __________.

side-effects

The functional programming property whereby any variable can be replaced with its actual value at any point during execution without changing program behavior is known as __________.

referential transparency

Functions that take other functions as arguments or return functions are classified as __________ functions.

higher-order

The functional language __________ is designed specifically for concurrency and distributed systems to process a large number of concurrent processes.

Erlang
