Create a Java class named HeadPhone to represent a headphone set. The class contains:

 Three constants named LOW, MEDIUM and HIGH with values of 1, 2 and 3 to denote the headphone volume.

 A private int data field named volume that specifies the volume of the headphone. The default volume is MEDIUM.

 A private boolean data field named pluggedIn that specifies if the headphone is plugged in. The default value is false.

 A private String data field named manufacturer that specifies the name of the manufacturer of the headphones.

 A private Color data field named headPhoneColor that specifies the color of the headphones.

 A private String data field named headPhoneModel that specifies the Model of the headphones.

 getter and setter methods for all data fields.

 A no argument constructor that creates a default headphone.

 A method named toString() that returns a string describing the current field values of the headphones.

 A method named changeVolume(value) that changes the volume of the headphone to the value passed into the method

Create a TestHeadPhone class that constructs at least 3 HeadPhone objects. For each of the objects constructed, demonstrate the use of each of the methods.

Here is what I have thus far....

import java.awt.Color;

public class HeadPhones {
    public static final int LOW = 1;
    public static final int MEDIUM = 2;
    public static final int HIGH = 3;

    private int volume;
    private boolean pluggedIn;
    private String manufacturer;
    private Color headPhoneColor;

    public HeadPhones() {
        volume = MEDIUM;
        pluggedIn = false;
        manufacturer = "";
        headPhoneColor = Color.BLACK;
    }
    /**
     *
     * @return volume of headphone
     */
    public int getVolume() {
        return volume;
    }
    /**
     * set volume of headphone
     *
     * @param volume
     */
    public void setVolume(int volume) {
        this.volume = volume;
    }
    /**
     *
     * @return true if the headphone is plugged in, false otherwise
     */
    public boolean getPluggedIn() {
        return pluggedIn;
    }
    /**
     * set plugged in
     *
     * @param pluggedIn
     */
    public void setPluggedIn(boolean pluggedIn) {
        this.pluggedIn = pluggedIn;
    }
    /**
     *
     * @return manufacturer
     */
    public String getManufacturer() {
        return manufacturer;
    }
    /**
     * set manufacturer
     *
     * @param manufacturer
     */
    public void setManufacturer(String manufacturer) {
        this.manufacturer = manufacturer;
    }
    /**
     *
     * @return headphone color
     */
    public Color getHeadPhoneColor() {
        return headPhoneColor;
    }
    public String getColorName() {
        String colorName = "Black";
        if (headPhoneColor == Color.BLACK || headPhoneColor == Color.black) {
            colorName = "Black";
        } else if (headPhoneColor == Color.WHITE || headPhoneColor == Color.white) {
            colorName = "White";
        } else if (headPhoneColor == Color.RED || headPhoneColor == Color.red) {
            colorName = "Red";
        } else if (headPhoneColor == Color.PINK || headPhoneColor == Color.pink) {
            colorName = "Pink";
        } else if (headPhoneColor == Color.CYAN || headPhoneColor == Color.cyan) {
            colorName = "Cyan";
        } else if (headPhoneColor == Color.BLUE || headPhoneColor == Color.blue) {
            colorName = "Blue";
        } else if (headPhoneColor == Color.GREEN || headPhoneColor == Color.green) {
            colorName = "Green";
        } else if (headPhoneColor == Color.GRAY || headPhoneColor == Color.gray) {
            colorName = "Gray";
        }
        return colorName;
    }
    /**
     * set headphone color
     *
     * @param headPhoneColor
     */
    public void setHeadPhoneColor(Color headPhoneColor) {
        this.headPhoneColor = headPhoneColor;
    }
    /**
     * returns a string describing the current field values of the headphone
     */
    public String toString() {
        StringBuilder s = new StringBuilder("(");
        s.append("manufacturer = ").append(manufacturer).append(", ");
        s.append("volumne = ").append(volume).append(", ");
        s.append("plugged in = ").append(pluggedIn).append(", ");
        s.append("color = ").append(getColorName()).append(")");
        return s.toString();
    }
}

And this is my test class....

import java.awt.Color;

public class TestHeadPhones {
    public static void main(String[] args) {
        HeadPhones[] headphones = new HeadPhones[3];

        headphones[0] = new HeadPhones();
        headphones[0].setHeadPhoneColor(Color.CYAN);
        headphones[0].setManufacturer("Thinksound");
        headphones[1] = new HeadPhones();
        headphones[1].setManufacturer("Monster");
        headphones[1].setHeadPhoneColor(Color.white);
        headphones[1].setPluggedIn(true);
        headphones[1].setVolume(HeadPhones.HIGH);
        headphones[2] = new HeadPhones();
        headphones[2].setManufacturer("Sennheiser");
        headphones[2].setHeadPhoneColor(Color.ORANGE);
        headphones[2].setPluggedIn(true);
        headphones[2].setVolume(HeadPhones.LOW);
        for (int i = 0; i < 3; i++) {
            System.out.println("Headphone #" + (i + 1));
            System.out.println("toString() results: " + headphones[i]);
            System.out.println("getVolume() results: " + headphones[i].getVolume());
            System.out.println("getPluggedIn() results: " + headphones[i].getPluggedIn());
            System.out.println("getManufacturer() results: " + headphones[i].getManufacturer());
            System.out.println("getHeadPhoneColor() results: " + headphones[i].getColorName() + "\n");
        }
    }
}

Please help.
