Number類shortValue()方法 (Number Class shortValue() method)

• shortValue() method is available in java.lang package.

  shortValue()方法在java.lang包中可用。

• shortValue() method is used to return the value denoted by this Number object converted to type short (by casting) and it may involve in rounding or truncations.

  shortValue()方法用于返回此Number對(duì)象表示的值，該值轉(zhuǎn)換為short類型(通過強(qiáng)制轉(zhuǎn)換)，并且可能涉及舍入或截?cái)唷?

• shortValue() 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.

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

• shortValue() method does not throw an exception at the time of conversion from number to short.

  shortValue()方法在將數(shù)字轉(zhuǎn)換為short時(shí)不會(huì)引發(fā)異常。

Syntax:

句法：

public short shortValue();

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 short, it returns a converted (from type number to short) value represented by this Number object.

此方法的返回類型為short ，它返回由此Number對(duì)象表示的轉(zhuǎn)換后的值(從類型編號(hào)到短型)。

Example:

例：

// Java program to demonstrate the example // of shortValue() method of Number classpublic class ShortValueOfNumberClass {public static void main(String[] args) {// Variables initializationfloat f1 = 10.58f;double d1 = 20.62;// It returns short value denoted by this object// and converted to a short by calling f.shortValue()Float f = new Float(f1);// Display f resultSystem.out.println("f.shortValue(): " + f.shortValue());// It returns short value denoted by this object// and converted to a short by calling d.shortValue()Double d = new Double(d1);// Display d resultSystem.out.println("d.shortValue(): " + d.shortValue());} }

Output

輸出量

f.shortValue(): 10 d.shortValue(): 20
