Question

java

1) Create a mutator method called setPosition that accepts one integer parameter. Update the

position variable by adding the position to the parameter variable.

2)debug the code

public class food

{

public static void main(String[] args) {

Fruits apple = new Fruits(20);

// Write the statement to call the method that will increase the instance variable position by 6.

Fruits.setPosition(6);

apple.getPosition();

}

}

Answer 1

public void setPosition(int amount) {
    this.position += amount;
}

public class Fruits {

    private int position;

    public Fruits(int position) {
        this.position = position;
    }

    public void setPosition(int amount) {
        this.position += amount;
    }

    public int getPosition() {
        return position;
    }
}

public class food {
    public static void main(String[] args) {
        Fruits apple = new Fruits(20);
        // Fix here: call setPosition on apple Object instead of Fruits class directly.
        apple.setPosition(6);
        System.out.println(apple.getPosition());
    }
}
