Java中的 ZoneOffset equal(Object) 方法及示例

Java.time 包中ZoneOffset 类的equals(Object)方法用于检查作为参数传递给此ZoneOffset 实例的另一个ZoneOffset 实例是否相等。此方法返回一个布尔值，说明相同。

句法：

public boolean equals(Object object)

参数：此方法接受一个参数对象，该对象将等于此 ZoneOffset 实例。

返回值：此方法返回一个布尔值，说明此 ZoneOffset 是否等于作为参数传递的实例。

下面的示例说明了 ZoneOffset.equals() 方法：

示例 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

示例 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
