使用Java中的Calendar类增加一个月
为Java中的Calendar类导入以下包
import java.util.Calendar;
首先，创建一个Calendar对象并显示当前日期
Calendar calendar = Calendar.getInstance();
System.out.println("Current Date = " + calendar.getTime());现在，让我们使用add()方法和Calendar.MONTH常数增加月份-
calendar.add(Calendar.MONTH, 2);
以下是一个例子
示例
import java.util.Calendar;
public class Demo {
public static void main(String[] args) {
Calendar calendar = Calendar.getInstance();
System.out.println("Current Date = " + calendar.getTime());
// Incrementing Month by 2
calendar.add(Calendar.MONTH, 2);
System.out.println("Updated Date (+2 Months) = " + calendar.getTime());
}
}输出结果
Current Date = Thu Nov 22 15:56:34 UTC 2018 Updated Date (+2 Months) = Tue Jan 22 15:56:34 UTC 2019
