TV CLASS 생성
class tv {
int channel;
int volume;
boolean power;
void setPower(){
power = !power;
}
void channelUp(){
channel++;
}
void channelDown(){
channel--;
}
void volumeUp(){
volume += 2;
}
void volumeDown(){
volume -= 3;
}
}
public class TvTest{
public static void main(String[] args){
tv t = new tv();
t.channel = 2;
t.volume = 0;
t.power = true;
t.volumeUp();
t.channelUp();
System.out.println("현재 볼륨 : "+t.volume);
System.out.println("현재 채널 : "+t.channel);
System.out.println("현재 파워 : "+t.power);
}
}
