Java中的 SimpleTimeZone hashCode() 方法及示例

SimpleTimeZone 类的hashCode()方法为 SimpleDateFormat 对象生成哈希码。

句法：

public int hashCode()

参数：该函数不接受任何参数。

返回值：它返回此对象的哈希码。

异常：该函数不抛出任何异常。

下面的程序演示了上述函数：

方案一：

// program to demonstrate the
// function java.util.SimpleTimeZone.hashCode()
  
import java.util.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // create simple time zone object
        SimpleTimeZone obj
            = new SimpleTimeZone(500, "US");
  
        System.out.println("SimpleTimeZone = "
                           + obj);
  
        // get hash code value and print
        System.out.println("Hash code is = "
                           + obj.hashCode());
    }
}

输出：

SimpleTimeZone: java.util.SimpleTimeZone
[ 
 id=US,
 offset=500,
 dstSavings=3600000,
 useDaylight=false,
 startYear=0,
 startMode=0,
 startMonth=0,
 startDay=0,
 startDayOfWeek=0,
 startTime=0,
 startTimeMode=0,
 endMode=0,
 endMonth=0,
 endDay=0,
 endDayOfWeek=0,
 endTime=0,
 endTimeMode=0
]
Hash code is = 500

方案二：

// program to demonstrate the
// function java.util.SimpleTimeZone.hashCode()
  
import java.util.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // create simple time zone object
        SimpleTimeZone obj
            = new SimpleTimeZone(500, "IN");
  
        System.out.println("SimpleTimeZone: "
                           + obj);
  
        // get hash code value and print
        System.out.println("Hash code is = "
                           + obj.hashCode());
    }
}

输出：

SimpleTimeZone: java.util.SimpleTimeZone
[ 
 id=IN,
 offset=500,
 dstSavings=3600000,
 useDaylight=false,
 startYear=0,
 startMode=0,
 startMonth=0,
 startDay=0,
 startDayOfWeek=0,
 startTime=0,
 startTimeMode=0,
 endMode=0,
 endMonth=0,
 endDay=0,
 endDayOfWeek=0,
 endTime=0,
 endTimeMode=0
]
Hash code is = 500
