There is a lab assignment. Basically includes array and some other basic stuff. Comment if you have any questions. Thank you.

I have got all classes here so that it might be more make sense.

        // QUESTION: Assume the Semi can somehow be added to the inventory list. Given the code in the lab
        // right now, could the dealership assign an MSRP to the semi? Why or why not? Note that
        // you do NOT need to make this possible in the code if it isn't possible. Just explain.
    }

Semi.java

public class Semi extends Commercial {

    private int numAxles;
    private double weight; // LBS

    // Constructors
    public Semi() {
        super();
        numAxles = 0;
        weight = 0.0;
    }

    public Semi(String pVIN, String comID) {
        super(pVIN, comID);
        numAxles = 0;
        weight = 0;
    }

    public Semi(String pVIN, String comID, int axleCount, double weightLBS) {
        super(pVIN, comID);
        numAxles = axleCount;
        weight = weightLBS;
    }

    // toString Method
    @Override
    public String toString() {
        return "Semi is " + super.toString();
    }

    // TODO Add setters and getters for numAxles and weight in the Semi class
    public int getNumAxles() {
        return numAxles;
    }

    public void setNumAxles(int numAxles) {
        this.numAxles = numAxles;
    }

    public double getWeight() {
        return weight;
    }

    public void setWeight(double weight) {
        this.weight = weight;
    }
}

Programming Language: JAVA In this assignment you will be sorting an array of numbers using the bubble sort algorithm. You must be able to sort both integers and doubles, and to do this you must overload a method. Bubble sort work by repeatedly going over the array, and when 2 numbers are found to be out of order, you swap those two numbers. This can be done by looping until there are no more swaps being made, or using a...
