AP Computer Science A 100& Correct What is encapsulation in object-oriented programming? Encapsulation is the concept of bundling data (fields) and methods (functions) that operate on the data into a single unit, typically a class. It helps to protect the internal state of an object and exposes only necessary parts through public methods. What does inheritance allow you to do in Java? Inheritance allows a subclass to inherit fields and methods from a superclass. This promotes co...

AP Computer Science Principles Vocabulary 100% Correct What is algorithm in computer science? An algorithm is a step-by-step procedure or formula for solving a problem or performing a task. It is a set of instructions designed to be followed in a specific order to achieve a desired outcome. Define abstraction and its role in programming. Abstraction is the process of simplifying complex systems by focusing on the essential features and ignoring the details. In programming, it h...

AP Computer Science Principles Exam with Verified Solutions What are algorithms, and why are they important in computer science? Algorithms are step-by-step procedures or formulas for solving problems. They are important because they provide a systematic way to solve computational problems and are foundational to programming and problem-solving in computer science. How does abstraction help in programming? Abstraction helps in programming by allowing programmers to manage comp...

AP Computer Science A Questions and Answers 100% Pass Consider the following code segment: ```java int[] numbers = {1, 2, 3, 4, 5}; int sum = 0; for (int i = 0; i < h; i++) { sum += numbers[i]; } ``` What does the code segment do? The code segment calculates the sum of all the elements in the `numbers` array and stores the result in the `sum` variable. The final value of `sum` will be 15. Consider the following code segment: ```java String str = "hello"; 2 st...

AP Computer Science Principles 100% Correct What is a `list comprehension` in Python, and how is it used? A `list comprehension` in Python is a concise way to create lists using a single line of code. It allows for the generation of lists by applying an expression to each element in an iterable, optionally filtering elements based on a condition. How does a `recursive` function work, and what is its purpose? A `recursive` function is a function that calls itself to solve a pro...
