bytevalue_Java Number byteValue()方法与示例
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對象表示的值(轉換為字節類型)(通過強制轉換)。
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()方法是一種非靜態方法,只能通過類對象訪問,如果嘗試使用類名訪問該方法,則會收到錯誤消息。
byteValue() method does not throw an exception at the time of conversion from Number to byte.
從Number轉換為字節時, byteValue()方法不會引發異常。

此方法的返回類型為byte ,它返回一個由此Number對象表示的轉換后的值(從Number類型轉換為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
