长类shortValue()方法 (Long 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 Long object converted to type short (by casting).

  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。

// 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());
    }
}
