hashCode() method is available in java.lang package.
hashCode()方法在java.lang包中可用。
hashCode() method is used to return hashcode of the Short object.hashCode()方法用于返回Short对象的哈希码。
hashCode() 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.hashCode()方法是一个非静态方法，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。

// by calling ob1.hashCode()
Short ob1 = new Short(value1);
// Display ob1 result
System.out.println("ob1.hashCode(): " + ob1.hashCode());
// It returns hashcode value denoted by this Short ob2 object
// by calling ob2.hashCode()
Short ob2 = new Short(value2);
// Display ob2 result
System.out.println("ob2.hashCode(): " + ob2.hashCode());
}
