Java 中的 ZoneOffset equal(Object)方法，示例

原文:https://www . geesforgeks . org/zone offset-equal object-in-Java-method-with-examples/

java.time 包中 ZoneOffset 类的 equals(Object) 方法用于检查作为参数传递给该 ZoneOffset 实例的 ZoneOffset 的另一个实例是否相等。此方法返回一个表示相同内容的布尔值。

语法:

public boolean equals(Object object)

参数:这个方法接受一个参数对象，它等于这个区域偏移实例。

返回值:该方法返回一个布尔值，说明该区域偏移量是否等于作为参数传递的实例。

以下示例说明了 ZoneOffset.equals()方法:

例 1:

// Java code to illustrate equals() method

import java.time.*;

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

        // Get the ZoneOffset instance
        ZoneOffset zoneOffset1
            = ZoneOffset.ofHours(5);
        System.out.println("ZoneOffset 1: "
                           + zoneOffset1);

        // Get the ZoneOffset instance
        ZoneOffset zoneOffset2
            = ZoneOffset.ofHours(5);
        System.out.println("ZoneOffset 2: "
                           + zoneOffset2);

        // Using equals() method
        System.out.println("ZoneOffset 1 "
                           + "is equal to ZoneOffset 2: "
                           + zoneOffset1.equals(zoneOffset2));
    }
}

输出:

ZoneOffset 1: +05:00
ZoneOffset 2: +05:00
ZoneOffset 1 is equal to ZoneOffset 2: true

例 2:

// Java code to illustrate equals() method

import java.time.*;

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

        // Get the ZoneOffset instance
        ZoneOffset zoneOffset1
            = ZoneOffset.ofHours(5);
        System.out.println("ZoneOffset 1: "
                           + zoneOffset1);

        // Get the ZoneOffset instance
        ZoneOffset zoneOffset3
            = ZoneOffset.ofHours(3);
        System.out.println("ZoneOffset 3: "
                           + zoneOffset3);

        // Using equals() method
        System.out.println("ZoneOffset 1 "
                           + "is equal to ZoneOffset 3: "
                           + zoneOffset1.equals(zoneOffset3));
    }
}

输出:

ZoneOffset 1: +05:00
ZoneOffset 3: +03:00
ZoneOffset 1 is equal to ZoneOffset 3: false
