longvalue

短類longValue()方法 (Short class longValue() method)

• longValue() method is available in java.lang package.

  longValue()方法在java.lang包中可用。

• longValue() method is used to return the value denoted by this Short object converted to type long (by casting).

  longValue()方法用于返回此Short對象表示的值，該對象轉換為long類型(通過強制轉換)。

• longValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  longValue()方法是一個非靜態方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

• longValue() method does not throw an exception at the time of conversion from Short to long.

  從Short轉換為long時， longValue()方法不會引發異常。

Syntax:

句法：

    public long longValue();

Parameter(s):

參數：

• It does not accept any parameter.

  它不接受任何參數。

Return value:

返回值：

The return type of this method is long, it returns a converted (from type short to long) value represented by this Short object.

此方法的返回類型是long ，它返回一個由此Short對象表示的轉換后的值(從short類型轉換為long類型)。

Example:

例：

// Java program to demonstrate the example 
// of longValue() method of Short class
public class LongValueOfShortClass {
public static void main(String[] args) {
// Variables initialization
short s1 = 20;
short s2 = 30;
// It returns short value denoted by this Short ob1 object
// and converted to a long by calling ob1.longValue()
Short ob1 = new Short(s1);
// Display ob1 result
System.out.println("ob1.longValue(): " + ob1.longValue());
// It returns short value denoted by this Short ob2 object
// and converted to a long by calling ob1.longValue()
Short ob2 = new Short(s2);
// Display ob2 result
System.out.println("ob2.longValue(): " + ob2.longValue());
}
}

Output

輸出量

ob1.longValue(): 20
ob2.longValue(): 30
