A-LevelComputer ScienceObject-Oriented Programming (OOP)Oct/Nov 2021Paper 4 Q230 Marks

A program, written using object-oriented programming, stores pictures as objects. The program stores the dimensions of the picture (width and height), the colour of the frame (e.g. black), and a description of the picture (e.g. flowers). The class has the following attributes and methods. Description : STRING // stores a description of the picture Width : INTEGER // stores the width e.g. 30 Height : INTEGER // stores the height e.g. 40 FrameColour : STRING // stores the colour e.g. black Constructor() // takes all four values as parameters and sets them to the private attributes GetDescription() // returns the description of the picture GetHeight() // returns the height GetWidth() // returns the width GetColour() // returns the frame colour SetDescription() // takes the new description as a parameter and writes the value to description
