Question

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 please

CAR Class :

public class Car {

   private int yearModel;
   private String make;
   private int speed;
  
   public Car(int yM, String m){
       setYearModel(yM);
       setMake(m);
       setSpeed(0);
   }
   void accelerate() {
       setSpeed(getSpeed()+5);
   }
   void brake() {
       setSpeed(getSpeed()-5);
   }
   public int getYearModel() {
       return yearModel;
   }
   public void setYearModel(int yearModel) {
       this.yearModel = yearModel;
   }
   public String getMake() {
       return make;
   }
   public void setMake(String make) {
       this.make = make;
   }
   public int getSpeed() {
       return speed;
   }
   public void setSpeed(int speed) {
       this.speed = speed;
   }
   void getCurrentSpeed() {
       System.out.println("Current Speed of the Car object "+getMake()+" "+getYearModel()+" is "+getSpeed());
   }
}

PSEUDOCODE :-

car class

   private interger variable 'yearModel'
   private String variable 'make'
   private interger variable 'speed'
  
   public contructor 'car' takes two arguments - 'integer argument1 , String argument2'
       set the year of model to argument1
       set maker to argument2
       set speed to 0
  
  
   void method 'accelerate'
       increase the value of variable 'speed' of object by 5 units
  
  
   void method 'brake'
       decrease the value of variable 'speed' of object by 5 units
  

   public integer method 'getYearModel'
       returns the variable 'yearModel'

   public void method 'setYearModel' takes an integer argument
       set the value of passed argument to the variable 'yearModel'
  

   public String method 'getMake'
       returns the variable 'make'
  

   public void method 'setMake' takes an String argument
       set the value of passed argument to the variable 'make'
  

   public integer method 'getSpeed'
       returns the value of variable 'speed'

   public void method 'setSpeed' takes an integer argument
       set the value of passed argument to the variable 'speed'
  

   void method 'getCurrentSpeed'
       appends the details of the car object on console

exit

FLOW CHART :-

MAIN Class :

public class Main {

   public static void main(String[] args) {
      
       Car car1 = new Car(1998,"FORD");
       Car car2 = new Car(1995,"LOTUS");
      
       for(int i = 0 ; i < 5 ; i++ ) {

           car2.brake();
           car2.getCurrentSpeed();
       }
      
   }
  
}

PSEUDOCODE :-

main class

main method
  
   first object of car is initiated using constructor
   second object of car is initiated using constructor

   for range 0 to 4
       first object of car accelerates
       appends the updated speed

   for range 0 to 4
       first object of car decelerates
       appends the updated speed

   for range 0 to 4
       second object of car accelerates
       appends the updated speed

   for range 0 to 4
       second object of car decelerates
       appends the updated speed
