雙類shortValue()方法 (Double 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 Double object converted to type short (by casting).

  shortValue()方法用于返回此Double對象表示的值，該值轉換為short類型(通過強制轉換)。

• shortValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with class name then we will get an error.

  shortValue()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。

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

  在從double轉換為short時， shortValue()方法不會引發異常。

例：

// Java program to demonstrate the example // of shortValue() method of Double classpublic class ShortValueOfDoubleClass {public static void main(String[] args) {// Variables initializationdouble d1 = 18.20;double d2 = 19.20;// It returns double value denoted by this Double value1 object// and converted to a short by calling value1.shortValue()Double value1 = new Double(d1);// Display value1 resultSystem.out.println("value1.shortValue(): " + value1.shortValue());// It returns double value denoted by this Double value2 object// and converted to a short by calling value2.shortValue()Double value2 = new Double(d2);// Display value2 resultSystem.out.println("value2.shortValue(): " + value2.shortValue());} }

Output

輸出量
