  shortValue()方法用于返回由此Long对象表示的值，该对象转换为short类型(通过强制转换)。

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

  shortValue()方法是一种非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

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

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 long to short) value represented by this Long object.

此方法的返回类型为short ，它返回由此Long对象表示的转换后的值(从long型到short型)。

Example:

例：

// Java program to demonstrate the example 
// of shortValue() method of Long class
public class ShortValueOfLongClass {
public static void main(String[] args) {
// Variables initialization
long l1 = 10;
long l2 = 20;
// It returns long value denoted by this Long ob1 object
// and converted to a short by calling ob1.shortValue()
Long ob1 = new Long(l1);
// Display ob1 result
System.out.println("ob1.shortValue(): " + ob1.shortValue());
// It returns long value denoted by this Long ob2 object
// and converted to a short by calling ob2.shortValue()
Long ob2 = new Long(l2);
// Display ob2 result
System.out.println("ob2.shortValue(): " + ob2.shortValue());
}
}

Output

输出量
