Write a class called TV with attributes: channel, volumeLevel, on_Off_state. The default values should be 1 for channel (only channels 1 to 100 are allowed), 5 for volumeLevel (only volumeLevels 1 to 10 are allowed), and OFF for on_Off_state (only ON and OFF are allowed). The TV class should allow the user to create a default TV and a TV with given parameters for channel, volumeLevel, on_Off_state. User should be able to set the TV channel to any channel, or increment or decrement the channel within the channel range. User can only increment or decrement volumeLevel within the valid range. User should be able switch the TV ON or OFF. User should be able read the current state of TV (i.e. values of channel, volumeLevel, and on_Off_state).

The Hal9000 has one constructor which takes a String parameter of a name of the crew member it is interacting with. It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter. Supply Javadoc for the constructor and all the methods
