We want to add a button to the tally counter in Section 3.1 that allows an operator to undo an accidental button click. Provide a method public void undo ) that simulates such a button. As an added precaution, make sure that clicking the undo button cannot take the counter to less than zero. (Hint: The call Math.ma. (, returns n if n is greater than zero, zero otherwise.) Add the capability for a tally counter that can be used to admit a limited number of people. First the limit is set with a call public void setLimit(int newLimit) If the click button is clicked more often than the limit it has not effect Hint The call Math.min(n,limit) returns n if n is less than limit. and limit otherwise. Your declaration for limit should be: int limitnte a large value by default.)
