从日历中减去？ [英] Subtraction from calendar ?

问题描述

public int yearWorked(){

int totalWorked =
    GregorianCalendar.getInstance(YEAR) - this.hiringDate.get(Calendar.YEAR); // is this logic correct ?

return totalWorked;
}

我想计算员工工作的年数。所以我想要的是从当前日期和当前员工做一个简单的减法，但我的语法是错误的：（

I want to calculate the years that an employee has worked. So what i am trying is to make a simple subtraction from current date and the current employee ,but my syntax is wrong :(

推荐答案

试试这个：

Try this:

GregorianCalendar today = new GregorianCalendar();
int totalWorked = today.get(Calendar.YEAR) - hiringDate.get(Calendar.YEAR);

hiringDate 也必须是 GregorianCalendar 的实例。
