For Questions 30 through 37 , we will assume that class TelevisionChannel has three fields: name, a String; number, an integer; and cable, a boolean, which represents whether the channel is a cable channel. 30. Code a default constructor for that class: initialize the fields to an empty string, 0 , and false, respectively. If your default constructor code goes here 31. Code a constructor for that class that takes three parameters. // your constructor code goes here 32. Code the three accessors for that class. if your code goes here 3. . Code the three mutators for that class. Il your code goes here 3. Code the tostring method. 7) your code goes here 3. Code a method returning the number of digits in the channel number. For instance, if the channel number is 21 , the method returns 2 ; if the channel number is 412 , the method returns 3 . 1/ your code goes here 37 Code a method returning the word cable if the current object represents a cable channel and returning the word network if the current object does not represent a cable channel. // your code goes here
