找出处理用户多少次？

Question

我在部分作业上遇到了麻烦。在循环运行一次后，它询问用户是否要处理另一个雇员时，我必须查看我的程序中雇员被处理了多少次。如果他们输入y表示是，然后在第二次计算雇员之后输入n表示结束。我想说“已处理的雇员数：2”。我该怎么办？

package paytime;

Answer 1

您可以通过简单地使“ int employeeProcessed = 0;”来实现。在while循环之外，然后添加“ employeesProcessed ++;”直接在“ if（cho（equice.equalsIgnoreCase（“ Y”）））”之后，因此每次要求您的程序处理雇员时，您都要向int加1，以跟踪您处理了多少名员工。然后，您可以将此变量添加到打印字符串的末尾，使其显示“已处理的员工总数：” + employeeProcessed。
