Java SimpleTimeZone hashCode()用法及代码示例

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

用法:

public int hashCode()

参数：该函数不接受任何参数。

返回值：它返回该对象的哈希码。

异常：该函数不会引发任何异常。

下面的程序演示了上述函数：

示例1:

// 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

示例2:

// 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
