下面是 Period.toTotalMonths()方法的实现:

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

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
