A-LevelComputer ScienceObject-Oriented Programming (OOP)May/June 2023Paper 4 Q232 Marks

A computer game is being designed that will include different vehicles. A prototype for the game is being developed using object-oriented programming. The class Vehicle stores data about the vehicles. Each vehicle has an identification name, a maximum speed, a current speed and a horizontal position. The value IncreaseAmount is added to the current speed each time the vehicle increases its speed. Vehicle ID: STRING stores the identification name for the vehicle MaxSpeed : INTEGER stores the maximum speed CurrentSpeed : INTEGER stores the current speed IncreaseAmount : INTEGER stores the amount CurrentSpeed increases by HorizontalPosition : INTEGER stores the horizontal position Constructor() initialises ID, MaxSpeed and IncreaseAmount to the parameter values initialises both CurrentSpeed and HorizontalPosition to 0 GetCurrentSpeed() returns the current speed GetIncreaseAmount() returns the increase amount GetHorizontalPosition() returns the horizontal position GetMaxSpeed() returns the maximum speed SetCurrentSpeed() assigns the parameter to the current speed SetHorizontalPosition() assigns the parameter to the horizontal position IncreaseSpeed() calculates and stores the new speed and horizontal position of the vehicle
