Java 中的计时周期等于()方法，示例

原文:https://www . geeksforgeeks . org/chronoperiod-equals-method-in-Java-with-examples/

Java 中计时周期界面的等于()方法用于检查两个给定周期是否相等。

这种比较是基于计时周期类型以及三年、三个月和三个日期中的每一个。要相等，所有三年、月和日期必须各自相等。

语法:

boolean equals(ChronoPeriod secondChronoPeriod)

参数:此方法接受单个参数秒时周期，这是另一个要比较的周期。

返回值:如果给定周期相等，上述方法返回真，否则返回假。

下面的程序说明了上述方法:

程序 1:

// Java code to show the period
// equals for two given periods

import java.time.*;
import java.time.chrono.*;

public class ChronoPeriodClass {

    // Function to check if two given periods
    // are equals or not
    static boolean
    checkIfEqualChronoPeriod(ChronoPeriod firstChronoPeriod,
                             ChronoPeriod secondChronoPeriod)
    {

        return firstChronoPeriod.equals(secondChronoPeriod);
    }

    // Driver Code
    public static void main(String[] args)
    {

        // Given period
        ChronoPeriod first = Period.ofDays(28);
        ChronoPeriod second = Period.ofDays(8);

        System.out.println(
            checkIfEqualChronoPeriod(first, second));
    }
}

输出:

false

程序二:

// Java code to show the period
// equals for two given periods

import java.time.*;
import java.time.chrono.*;

public class ChronoPeriodClass {

    // Function to check if two given periods
    // are equals or not
    static boolean
    checkIfEqualChronoPeriod(ChronoPeriod firstChronoPeriod,
                             ChronoPeriod secondChronoPeriod)
    {

        return firstChronoPeriod.equals(secondChronoPeriod);
    }

    // Driver Code
    public static void main(String[] args)
    {

        // Given period
        ChronoPeriod first2 = Period.ofDays(28);
        ChronoPeriod second2 = Period.ofDays(28);

        System.out.println(
            checkIfEqualChronoPeriod(first2, second2));
    }
}

输出:

true
