modulo - BlueJ为什么说模不是语句？(Why does BlueJ say that modulo isn't a statement?)

Question

For school I have to make a little program that makes Ticket Id's.

(对于学校，我必须编写一个可以制作票证编号的小程序。)

One task says: "The ticket ID is the age modulo the length of the first name + the length of the last name. I've tried this:

(一个任务说：“票证ID是姓氏的长短+姓氏的长短的模数。我已经尝试过：)

TicketID = firstname + lastname;

(TicketID =名字+姓氏;)

TicketID.length() % age;

(TicketID.length（）％年龄；)

I get the error that the % is not a statement.

(我收到％不是语句的错误。)

If you could help me that would be amazing.

(如果您能帮助我，那将是惊人的。)

Answer 1

You need to assign the result of % to some other variable

(您需要将％的结果分配给其他变量)

TicketID = firstname + lastname;

(here) = TicketID.length() % age;
