Java 中的 Period ofYears()方法，带示例

原文:https://www . geesforgeks . org/period-of yers-in-Java-method-in-examples/

周期类的年(int number of yers)方法用于从给定的年数中获取一个周期作为参数。获得的周期将代表年数。单位月和日应保持为 0。

语法:

public static Period ofYears(int numberOfYears)

参数:该方法接受代表年数的整数型单参数年数。它可以是消极的，也可以是积极的。

返回值:这个方法必须返回一个周期，代表年数。

异常:此方法不抛出任何异常。

下面的程序说明了 Java 中 Period 的 ofYears()方法:

程序 1:

// Java program to demonstrate
// Period ofYears(int numberOfYears) method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // Create Period object
        Period period
            = Period.ofYears(5);

        // Print period
        System.out.println("Years: "
                           + period.getYears());
        System.out.println("Months: "
                           + period.getMonths());
        System.out.println("Days: "
                           + period.getDays());
    }
}

Output:

Years: 5
Months: 0
Days: 0

程序 2:

// Java program to demonstrate
// Period ofYears(int numberOfYears) method
import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        int numberOfYears = -10;

        // Create Period object
        Period period
            = Period.ofYears(numberOfYears);

        // Print period
        System.out.println("Years: "
                           + period.getYears());
        System.out.println("Months: "
                           + period.getMonths());
        System.out.println("Days: "
                           + period.getDays());
    }
}

Output:

Years: -10
Months: 0
Days: 0
