  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对象表示的值，该对象转换为byte类型(通过强制转换)。

• 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()方法是一种非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

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

  从Short转换为byte时， byteValue()方法不会引发异常。

Syntax:

句法：

    public byte byteValue();

Parameter(s):

参数：

• It does not accept any parameter.

  它不接受任何参数。

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.

此方法的返回类型为byte ，它返回一个由此Short对象表示的转换后的值(从Short类型转换为byte类型)。

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

输出量

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