我创建了一个if语句,如果按下某个键,该语句将创建字符串的变量。然后,我想在最后添加所有创建的变量,以便可以将其作为票务程序输出。我还需要帮助,因为我如何使字符'X'停止while循环,我本质上想要做的就是允许用户选择一个部分,然后打印出他们选择的部分,以及总共。请帮助。

class ticket{
char selection; //The Letter of Selection The User will choose ex. A, B, C etc.
String ticketType; //The type of ticket the user will choose ex. Courtside Prime, Baseline Prime etc.
double price; //The price of each ticket
}
它最终会打印出他们合计的总数和他们在击中x之后选择的票证部分,我想结束while循环,但不知道如何
这是问题的重要部分。 if后的分号使其成为空的条件块。其余代码始终执行。这只是一个示例,每个if语句都有此问题。
if (choice == 'A');{
a = first.price;
a1 = first.ticketType;
}
应该像这样
if (choice == 'A') {
a = first.price;
a1 = first.ticketType;
}
您可能不希望第一行要求用户输入。
char choice;
// choice = c.readChar();
while(choice != 'X') {
c.println("Enter the letter of the seat section you would like to select");
choice = c.readChar();
