New to Java Need help with Homework

[cjg2283]

I have my program that does what it needs to but I want it to be able to do one more thing and i can't seem to figure out how. This program ask what make,year,speed of a car, I also have where you can have the car accelerate or brake. The program works if you accelerate or brake once. I want to be able to accelerate or break 5 times then show the speed. Can somebody point me into the right direction? Thanks for the help!

import java.util.Scanner;
public class Car{
    Scanner kb = new Scanner(System.in);
    private int yearModel;
    private String make;
    private int speed;
    private int acc;
    private int count = 0;
    public Car() {
        this.yearModel = yearModel;
        this.make = make;
        this.speed = speed;
    }

    
    
    public void SetMake(){
    this.make = kb.next();
    }
    public void SetYearModel(){
    this.yearModel = kb.nextInt();
    }
    public void SetSpeed(){
    this.speed = kb.nextInt();
    }
    
    
    
    
    public void Accel() {
       
        this.acc = kb.nextInt();
        while (count <= 5) 
        count++;
        {
             
            if (this.acc == 5) {
                this.speed = speed + 5;

            } else if (this.acc == -5) {
                this.speed = speed - 5;

            } else if (this.acc == 0) {
                this.speed = speed;

            } else {
                System.out.println("Goodbye");
                System.exit(0);
            }
        
          
    }
    }

the problem is that you are executing a loop with no body

your loop is just this part

  while (count <= 5) 
        count++;

none of the if statements get executed

you should put your increment at the end of the loop's body

  while (count <= 5) 
{
        //if statements{
        //}

        count++; 
} //end while loop

and by the way you have count = 0 and the while loop is set to test until <=5, so it will be executed 6 times not 5.
