bytevalue

Number類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對(duì)象表示的值(轉(zhuǎn)換為字節(jié)類型)(通過(guò)強(qiáng)制轉(zhuǎn)換)。

• 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()方法是一種非靜態(tài)方法，只能通過(guò)類對(duì)象訪問(wèn)，如果嘗試使用類名訪問(wèn)該方法，則會(huì)收到錯(cuò)誤消息。

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

  從Number轉(zhuǎn)換為字節(jié)時(shí)， byteValue()方法不會(huì)引發(fā)異常。

Syntax:

句法：

public byte byteValue();

Parameter(s):

參數(shù)：

• It does not accept any parameter.

  它不接受任何參數(shù)。

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.

此方法的返回類型為byte ，它返回一個(gè)由此Number對(duì)象表示的轉(zhuǎn)換后的值(從Number類型轉(zhuǎn)換為byte類型)。

Example:

例：

// Java program to demonstrate the example // of byteValue() method of Number classpublic class ByteValueOfNumberClass {public static void main(String[] args) {// Variables initializationint 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 resultSystem.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 resultSystem.out.println("f.byteValue(): " + f.byteValue());} }

Output

輸出量

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