Questions and Answers

Which of the following programming concepts is best described as the bundling of data and methods that operate on that data, restricting access to some of the object's components?

  • Abstraction
  • Inheritance
  • Encapsulation (correct)
  • Polymorphism

In the context of object-oriented programming, what is a 'class'?

  • A collection of related functions in a module.
  • A keyword used to define loops in programming.
  • A specific instance of an object with defined properties.
  • A blueprint for creating objects, defining their properties and behaviors. (correct)

What distinguishes a 'value parameter' from other types of parameters in programming?

  • It only allows integer values to be passed as arguments.
  • It passes the actual memory location of the argument to the function.
  • It automatically updates the original variable with any changes made in the function.
  • It passes a copy of the argument's value to the function. (correct)

Flashcards

What is a subprogram (function)?

A general term for a block of code that performs a specific task and can be reused.

What is a value parameter?

A type of parameter that passes a copy of the argument's value to the function, not the original value itself.

What does asynchronous mean in programming?

Type of operation that runs independently of the main program flow, allowing additional tasks to happen without waiting for others to complete.

What is bytecode?

Low-level, platform-independent code executed by a virtual machine, typically produced by compiling source code. Allows code to run on different operating systems.

Study Notes

  • Subprogram, also called a function, refers to a block of code designed to perform a specific task and be reused throughout a program.
  • Value parameter is a parameter type that sends a copy of the argument's value to the function.
  • Asynchronous operation operates independently from the main program flow, allowing other tasks to proceed without waiting for the prior operation to complete.
  • Bytecode is a low-level, platform-independent code form. It is executed by a virtual machine and is generally the output of compiling source code.
  • Case sensitivity in programming means the language distinguishes between uppercase and lowercase letters.
  • Class is a blueprint for creating objects and defines what properties and behaviors the objects will have in object-oriented programming.
  • Compiler is a tool that translates source code, written in a high-level language, into machine code or bytecode that a computer can execute.
  • Encapsulation involves bundling data and methods that operate on data into a single unit (a class), which restricts access to some of the object's components.
  • Field is a variable associated with a class or an object, that represents a piece of data stored in that object.
  • Inheritance includes creating a new class based on an existing one, taking its properties and methods, then adding or modifying them.
