Java 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这个ZoneOffset实例的另一个ZoneOffset实例是否相等。该方法返回一个布尔值，说明两者相同。

语法

public boolean equals(Object object)

参数： 该方法接受一个参数 对象 ，该对象将等于这个ZoneOffset实例。

返回值： 该方法返回一个 布尔值 ，说明这个ZoneOffset是否等于作为参数传递的那个实例。下面的例子说明了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
