A Counter Class The single instance variable (counter ) of a Counter object holds a non-negative integer. The methods of the Counter class allow a client to add 1 to counter , set the value of counter to zero, and retrieve the current value of counter . The default constructor sets counter to zero, and the one-argument constructor initializes counter to a non-negative integer. Implement a Counter class and test your class by writing a main(...) method that • instantiates a Counter object, • interactively reads a sequence of integers until a zero is entered, • and uses the Counter object to determine how many non-zero integers comprise the sequence

Question
A Counter Class
The single instance variable (counter ) of a Counter object holds a non-negative integer. The
methods of the Counter class allow a client to add 1 to counter , set the value of counter to zero,
and retrieve the current value of counter . The default constructor sets counter to zero, and the
one-argument constructor initializes counter to a non-negative integer.
Implement a Counter class and test your class by writing a main(...) method that
• instantiates a Counter object,
• interactively reads a sequence of integers until a zero is entered,
• and uses the Counter object to determine how many non-zero integers comprise the
sequence
