The Person Class

Define a class called Person which has attributes called height , money , ticketCount and hasPass.

The money and height variables are floats representing the amount of money the person currently has and the person's height (in inches).

The ticketCount is an integer indicating the number of tickets the person
currently has and hasPass is a boolean indicating whether or not the
person has a pass to get on the rides (assume a person can have at most 1
pass).

Write a constructor & all necessary methods in the Person class so that the
following code produces the output as shown below:

class PersonTester {
    public static void main(String args[]) {
    Person mary;

    mary = new Person(4.9f, 20.00f);

    System.out.println(mary.height);
    System.out.println(mary.money);
    System.out.println(mary.ticketCount);
    System.out.println(mary.hasPass);
    System.out.println(mary); // Notice that the money is properly formatted

    mary.ticketCount = 3;
    System.out.println(mary);

    mary.useTickets(2); // You have to write this method
    System.out.println(mary);

    mary.hasPass = true;
    System.out.println(mary);
}
}

Here is the output that your program MUST produce:

4.9
20.0
0
false
4.9' person with $20.00 and 0 tickets
4.9' person with $20.00 and 3 tickets
4.9' person with $20.00 and 1 tickets
4.9' person with $20.00 and a pass


Make sure to test your class with the test code above BEFORE you continue.

谢谢啊，这个很好，但是我不明白那个count++起什么作用啊，我看不出来，可以解释一下吗
