このプログラムを停止して戻ってテレビのオンとオフを切り替えるにはどうすればよいですか?
OFFを選択した場合、テレビの現在のステータスを表示したいと思います。
import java.util.Scanner;
public class TvTest
{
    public static void main (String[] args)
    {
        String x;
        String y;
        boolean tvStatus = false;
        int chan;
        int volu;
        Scanner input = new Scanner(System.in);
        TV tv2 = new TV(false,2,10);
        // Print out the current status of our TV
        System.out.print(tv2);
        System.out.println();
             System.out.print("Turn TV On or Off ?");
             x = input.nextLine();
             if(x.equalsIgnoreCase("on"))
               {
                   tvStatus = true;
               }else if(x.equalsIgnoreCase("off"))
               {
                   tvStatus =false;
               }
            System.out.print("Change the Channel to : ");
            chan = input.nextInt();
            System.out.print("Increase the volume by 1 or Decrease by -1 : ");
            volu = input.nextInt();
            TV tv1 = new TV(tvStatus,chan,volu);
            if(volu == 1)
            {
                tv1.incrementVolume();
            }else if (volu == -1)
            {
                tv1.decrementVolume();
            }
            System.out.println(tv1);
    }

これが私のテレビクラスです。toStringメソッドまたは私のセッターを改善する方法があるはずだと思います
