Car class Question

Design a class named car that has the following fields: YearModel: The yearModel field is an integer that holds the car's year model. Make: The make field references a string that holds the make of the car. Speed: The speed field is an integer that holds the car's current speed. In addition, the class should have the following constructor and other methods: Constructor: The constructor should accept the. car's year model and make as arguments. The values should be assigned to the object's yearModel and make fields. The constructor should also assign 0 to the speed field. Accessors: Design appropriate accessor methods to get the values stored in an object's yearModel, make, and speed fields. Accelerate: The accelerate method should add 5 to the speed field each time it is called. Brake: The brake method should subtract 5 from the speed field each time it is called. Next, design a program that creates a car object, and then cals the accelerate method fibe times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method 5 times. After each call to the brake method, get the current speed of the car and display it.

Thanks for the help guys (pseudocode and flowchart only) please no java code!!!!

Answer 1

For the above problem the pseudocode is as follows:

1. Begin
2. Declaring and defining class named Car
3. Variables for Car are declared as follows:
   1. Public variables
   2. int YearModel // it holds the car’s year model
   3. string Make // it holds the car’s make i.e. the brand
   4. int Speedfield // holds the current speed of the car
4. Create and define constructor named Car, make it public // constructor name is same as class
5. Declare Car as int year, string make
   1. YearModel is assigned the value of year
   2. Make is assigned the value of make
   3. Initialize Speedfield as 0
6. Declare and define accessor methods
   1. int YEAR // to get the YearModel
      1. Takes no arguments
      2. Returns the YearModel
   2. string MAKE // to get the Make
      1. Takes no argument
      2. Returns the Make
   3. int SPEED // to get current speed
      1. Takes no arguments
      2. Returns Speedfield
   4. void Accelerate // add acceleration to current speed
      1. No return type
      2. Add 5 to the current speed when it is called.
   5. Void Brake // for braking mechanism
      1. No return type
      2. if Speedfield is greater than or equal to 5
      3. then subtract 5 from Speedfield
      4. else Speedfield is set to 0
7. Initialize main method with void return
   1. Declare Car type variable c. // creating an object
   2. Input the values for c:
      1. c.YEAR
      2. c.MAKE
   3. Print the details of Car c
   4. Declare variables call a and b
   5. For a is equal to 0 and a is less than 5 continue // calling Accelerate method 5 times
      1. Call c.Accelerate()
      2. Print current speed calling c.SPEED()
   6. For b is equal to 0 and b is less than 5 continue // calling Brake method 5 times
      1. Call c.Brake()
      2. Print current speed calling c.SPEED.
      3. if c.Brake() is equal to zero // i.e. the Speedfield becomes 0 as we started with 0 and accelerate with 5 and braking with 5
      4. Print “CAR HAS BEEN STOPPED”
   7. End of main method
8. End
