Java中的 Period toTotalMonths() 方法及示例

Period 类的toTotalMonths()方法用于获取给定期间的总月数。它返回一个描述相同的长值。

句法：

public long toTotalMonths()

参数：此方法不接受任何参数。

返回：此函数返回长值，即此期间的总月数。

下面是 Period.toToTotalMonths() 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
