1.2.4 Types of programming language

A style of in a high language. Program statements are in sub-programs called procedures and . Data is stored in global or local variables.

A low-level programming language. Has a one-to-one with machine code (binary). Uses to represent the instructions.

The binary by the

A method is a subroutine defined within a that describes the behaviour of objects created from that class. It can access and modify the object’s .

An instance of a class

Object Oriented Programming. A style of programming which defines classes, and objects. Includes the concepts of , inheritance and polymorphism.

A feature of object-oriented programming where a subclass defines a with the same identifier, parameters, and return type as a method in its superclass. The subclass version replaces the method, providing a new implementation for that behaviour.

The ability of different classes to define with the same identifier but different implementations, allowing the same operation to behave depending on the type of object that invokes it. Often implemented through method overriding.

A that extends another class. A subclass the methods and of the class it extends and can also have it's own methods and attributes.

A class that has been by another class.

Private within a class can only be accessed by the within the same class. Attributes cannot be accessed directly.

A programming language that allows the programmer to write instructions using and structures similar to English. It most of the details of how the computer hardware works, allowing the programmer to focus on solving the problem.

The of an instruction contains the data to be used by the instruction.

An addressing where the address of the operand is found by adding a constant value to the contents of an index .

The operand is an which contains an address where can be found.

A feature of object oriented programming a subclass has the same and methods of the superclass.

The process of creating an instance (an object) of a .
