双类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对象表示的值，该值转换为short类型(通过强制转换)。

• 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。

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

  在从double转换为short时， shortValue()方法不会引发异常。

Syntax:

句法：

    public short shortValue();

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

此方法的返回类型为short ，它返回由此Double对象表示的转换后的值(从double类型转换为short类型)。

Example:

例：

// Java program to demonstrate the example
// of shortValue() method of Double class
public class ShortValueOfDoubleClass {public static void main(String[] args) {// Variables initialization
double 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 result
System.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 result
System.out.println("value2.shortValue(): " + value2.shortValue());
}
}

Output

输出量

value1.shortValue(): 18
value2.shortValue(): 19
