Java 中()方法的周期，示例

原文:https://www . geeksforgeeks . org/Java 方法时期示例/

周期类的()方法的用于从给定的年数、月数和天数中获取周期作为参数。这些参数以整数的形式被接受。此方法返回给定年数、月数和天数的期间。

语法:

public static Period of(
        int numberOfYears, 
        int numberOfMonths,
        int numberOfDays)

参数:该方法接受以下参数:

  • Years : Used to indicate the years that may be negative.
  • Months : Indicates the number of months that may be negative.
  • Days : Indicates the number of days that may be negative.

返回:该函数返回期间，该期间是用给定的年、月和日解析的期间对象。

以下是()方法的实现。

例 1:

// Java code to demonstrate of() method

import java.time.Period;

class GFG {
    public static void main(String[] args)
    {

        // Get the number of Years
        int numberOfYears = 1;

        // Get the number of Months
        int numberOfMonths = 5;

        // Get the number of Days
        int numberOfDays = 21;

        // Parse the given amounts into Period
        // using of() method
        Period p
            = Period.of(numberOfYears,
                        numberOfMonths,
                        numberOfDays);

        System.out.println(p.getYears() + " Years\n"
                           + p.getMonths() + " Months\n"
                           + p.getDays() + " Days");
    }
}

输出:

1 Years
5 Months
21 Days

例 2:

// Java code to demonstrate of() method

import java.time.Period;

class GFG {
    public static void main(String[] args)
    {

        // Get the number of Years
        int numberOfYears = -2;

        // Get the number of Months
        int numberOfMonths = 10;

        // Get the number of Days
        int numberOfDays = -11;

        // Parse the given amounts into Period
        // using of() method
        Period p
            = Period.of(numberOfYears,
                        numberOfMonths,
                        numberOfDays);

        System.out.println(p.getYears() + " Years\n"
                           + p.getMonths() + " Months\n"
                           + p.getDays() + " Days");
    }
}

输出:

-2 Years
10 Months
-11 Days
