Question

Topic: Java Programming

Hello,

I have the following code attached below, and keep getting told that "Television" on the 23rd line "cannot be resolved to a type". It happens on this line of code...

Television portable = new Television("Sharp", 19);

Can you tell me how to fix this?

Beginning of code...

import java.util.Scanner;

public class TelevisionDemo {

{}

public static void main(String[] args)

{

// //create a Scanner object to read from the keyboard

Scanner keyboard = new Scanner(System.in);

// //declare variables

int station; //the user's channel choice

// //HERE IS WHERE YOU DO TASK #5

Television portable = new Television("Sharp", 19);

portable.power();

System.out.println("A " + portable.getScreenSize() + " inch " +

portable.getManufacturer() + " has been turned on.");

System.out.print("What channel do you want? ");

station = keyboard.nextInt();

//change the channel on the television

portable.setChannel(station);

portable.decreaseVolume();

portable.decreaseVolume();

System.out.println("Channel: " + portable.getChannel() +

" Volume: " + portable.getVolume());

}

}

Answer 1

public class Television {

    private String manufacturer;
    private int screenSize;
    private int channel;
    private int volume;
    private boolean status;

    public Television(String manufacturer, int screenSize) {
        this.manufacturer = manufacturer;
        this.screenSize = screenSize;
        volume = 20;
        status = false;
    }

    public String getManufacturer() {
        return manufacturer;
    }

    public void setManufacturer(String manufacturer) {
        this.manufacturer = manufacturer;
    }

    public int getScreenSize() {
        return screenSize;
    }

    public void setScreenSize(int screenSize) {
        this.screenSize = screenSize;
    }

    public int getChannel() {
        return channel;
    }

    public void setChannel(int channel) {
        this.channel = channel;
    }

    public void power() {
        status = !status;
    }

    public int getVolume() {
        return volume;
    }

    public void increaseVolume() {
        volume++;
    }

    public void decreaseVolume() {
        volume--;
    }
}
