bytevalue

Number类byteValue()方法 (Number 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 Number object converted to type byte (by casting).

  byteValue()方法用于返回此Number对象表示的值(转换为字节类型)(通过强制转换)。

• byteValue() method is a non-static method, it is accessible with class object only and if we try to access the method with 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 Number to byte.

  从Number转换为字节时， 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 Number to byte) value represented by this Number object.

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

Example:

例：

// Java program to demonstrate the example
// of byteValue() method of Number class
public class ByteValueOfNumberClass {public static void main(String[] args) {// Variables initialization
int i1 = 10;
float f1 = 20.62f;
// It returns byte value denoted by this Number object
// and converted to a byte by calling i.byteValue()
Integer i = new Integer(i1);
// Display i result
System.out.println("i.byteValue(): " + i.byteValue());
// It returns byte value denoted by this Number object
// and converted to a byte by calling f.byteValue()
Float f = new Float(f1);
// Display f result
System.out.println("f.byteValue(): " + f.byteValue());
}
}

Output

输出量

i.byteValue(): 10
f.byteValue(): 20
