时期类的toTotalMonths()方法用于获取给定时期中的月总数。它返回一个描述它的long值。
用法:
public long toTotalMonths()
参数：此方法不接受任何参数。
返回值：此函数返回long值，该值是此期间内的月总数。
下面是Period.toTotalMonths()方法的实现：
示例1:
// Java code to demonstrate toTotalMonths() method
import java.time.Period;
class GFG {
public static void main(String[] args)
{
// Get the String to be toTotalMonthsd
String period = "P1Y2M21D";
// Parse the String into Period
Period p = Period.parse(period);
System.out.println("Period: " + p);
// Get the total number of months
// using toTotalMonths() method
System.out.println("Total number of Months"
+ " in this Period: "
+ p.toTotalMonths());
}
}
输出：
Period: P1Y2M21D
Total number of Months in this Period: 14
示例2:
// Java code to demonstrate toTotalMonths() method
import java.time.Period;
class GFG {
public static void main(String[] args)
{
// Get the String to be toTotalMonthsd
String period = "-P1Y2M21D";
// Parse the String into Period
Period p = Period.parse(period);
System.out.println("Period: " + p);
// Get the total number of months
// using toTotalMonths() method
System.out.println("Total number of Months"
+ " in this Period: "
+ p.toTotalMonths());
}
}
输出：
Period: P-1Y-2M-21D
Total number of Months in this Period: -14
