如何使用while循环获得多个输入？

Question

我想制作一个程序，要求用户输入订票的客户数量，读取输入的数字，执行循环以询问每个客户的年龄，并决定每个客户的单价。到目前为止，我的代码只有if-else语句：

if (customerP <4){
    System.out.println("The unit Price of customer 1 is: 0");
}else {
    if(customerP <13) {
        System.out.println("The unit price of customer 1 is: 5");
    }else {
        if(customerP <19) {
            System.out.println("The unit price of customer 1 is: 8");
        }else {
            System.out.println("The unit price of customer 1 is: 10");
        }
    }    
}

我如何添加一个同时循环来询问每个客户的年龄？

Answer 1

下面提供了使用while循环的代码

Scanner sc = new Scanner(System.in);

int customerCount = sc.nextInt();

int[] ageOfCustomers = new int[customerCount];
int i=0;
while(customerCount-- > 0) {

    ageOfCustomers[i++] = sc.nextInt();
}

System.out.println(Arrays.toString(ageOfCustomers));

Answer 2

干得好：

Scanner scanner = new Scanner(System.in);

System.out.println("Enter No of Customers: ");
int noCustomers = scanner.nextInt();

if (noCustomers < 1) {
     throw new IllegalArgumentException("No of Customers has to be 1 or greater");
}

int[] customerAges = new int[noCustomers];

for (int i = 0; i < noCustomers; i++) {
    System.out.println("Enter age for customer: " + i);
    customerAges[i] = scanner.nextInt();
}

System.out.println("Ages: " + Arrays.toString(customerAges));
