public class Car {
private int speed;
private int mileage;
private String color;
private String brand;
public Car(int s, int m, String c, String b)
{
speed = 0; //just a placeholder

brand = "No Brand"; //just a placeholder
}
public int getSpeed()
{
return speed;
}
public int getMileage()
{
return mileage;
}
public String getColor()
{
return color;
}
public String getBrand()
{
return brand;
}
public boolean setSpeed(int s)
{
if(s == 0) {
System.exit(0);
}
else
this.speed = s;
return true;
}
public boolean setMileage(int m)
{
if(m == 0) {
System.exit(0);
}
else
this.mileage = m;
return true;
}
public boolean setColor(String c)
{
if(c == null) {
System.exit(0);
}
else
this.color = c;
return true;

MAINCODE
public class CarDemo {
public static void main(String[] args) {
Car c = new Car(12,4200,"Red","Ford");
System.out.println("Car speed: "+c.getSpeed()+" km/h");
System.out.println("Car mileage: "+c.getMileage()+" miles");
System.out.println("Car color: "+c.getColor());
System.out.println("Car brand: "+c.getBrand());
}
}
The ouput produce
Car speed : 0 km/h
Car mileage: 0 miles
Car color: null
Car brand: null
How do I change my code if the output that I want
Car speed : 12 km/h
Car mileage: 4200 miles
Car color: Red
Car brand: Ford
