• Have the following functionalities as methods:
  • turnOn
  • turnOff
  • isOn (boolean if it is turned on or off)
  • getChannelCount (Returns number of channels)
  • getActiveChannel
  • changeChannel (Safe guard to only work with available channels)
• Turned off by default. When turned off, the only command the TV accepts is “Turn ON”
