bytevalue

短類byteValue()方法 (Short class byteValue() method)

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

  byteValue()方法在java.lang包中可用。

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

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

• byteValue() 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.

  byteValue()方法是一種非靜態方法，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。

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

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

Syntax:

句法：

    public byte byteValue();

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 byte, it returns a converted (from type Short to byte) value represented by this Short object.

此方法的返回類型為byte ，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byte類型)。

Example:

例：

// Java program to demonstrate the example 
// of byteValue() method of Short class
public class ByteValueOfShortClass {
public static void main(String[] args) {
// Variables initialization
short s1 = 100;
short s2 = 200;
// It returns short value denoted by this Short ob1 object
// and converted to a byte by calling ob1.byteValue()
Short ob1 = new Short(s1);
// Display ob1 result
System.out.println("ob1.byteValue(): " + ob1.byteValue());
// It returns short value denoted by this Short ob2 object
// and converted to a byte by calling ob2.byteValue()
Short ob2 = new Short(s2);
// Display ob2 result
System.out.println("ob2.byteValue(): " + ob2.byteValue());
}
}

Output

輸出量

ob1.byteValue(): 100
ob2.byteValue(): -56
