Object Oriented Programming

Question 1

asynchronous

Answer 1

A task that runs separately from the program’s normal steps, so the program can continue without waiting for that task to finish.

Question 2

bytecode

Answer 2

A low-level, platform-independent set of instructions generated by a compiler, interpreter or hybrid system and executed by a virtual machine

Question 3

case sensitive

Answer 3

when a programming language treats uppercase and lowercase letters as different characters

Question 4

class

Answer 4

the essential patterns of methods and data that define the set a group of objects belong to.

Question 5

compiler

Answer 5

Translates entire high level program to bytecode or machine language. Program runs without compiler. Bytecode runs via VM and machine language via computer.

Question 6

encapsulation

Answer 6

When methods and data are self contained within objects, and they hide their internal details, which can’t be accessed by other code.

Question 7

field

Answer 7

The data categories defined in a class that determine what information each object will store

Question 8

inheritance

Answer 8

When a new class receives the data and behaviors of a previous class. The new class can modify them or add new ones, which prevents rewriting code from scratch.

Question 9

instantiate

Answer 9

When you create an object from a class using specific data

Question 10

interpreter

Answer 10

An interpreter is a program that executes source code directly, evaluating it one instruction at a time at runtime.

An interpreter is like a translator who translates and speaks each sentence as they read it, instead of translating the entire book first.

Question 11

method

Answer 11

a function defined within a class that describes the behaviors or actions an object can perform

Question 12

object

Answer 12

an instance of a class containing data and methods defined by the class, representing a specific entity in a program

Question 13

paradigm

Answer 13

The way you conceptualize how coding is done, which influences the system and problem solving of coding.

Question 14

polymorphism

Answer 14

When you can invoke the same method for different subclasses and get unique responses, even when referencing the superclass they all belong to.

Question 15

strong typing

Answer 15

When you associate data with a specific type, after which it becomes illegal to apply operators that are inappropriate for that data type. Helps catch errors early.
