bytevalue

短类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
