The program continually gets the number of people entering or leaving the restaurant. Ex: 2 means two people entered, and -3 means three people left. After each input, the program outputs the number of people in the restaurant. Once the number of people in the restaurant equals or exceeds 10, the program exits. If an Input MismatchException exception occurs, the program should get and discard a single string from input. Ex: The input "2 abc 8" should result in 10 occupants. Not all lines are used in the solution.
