Overview
Since the beginning of the JDK1.5, the syntactic sugar of automatic boxing/unpacking has been introduced, which makes the programmer's code more concise and eliminates the need for explicit conversions. Basic type and wrapper type under the action of some operators, the wrapper type calls the ValueOf () method to convert the original type value into the corresponding wrapper class object, called Automatic
unpacking, and the English language corresponds to unboxing, and the Chinese translation is unboxing.Before the Java SE5, to be boxed, you can use the following code:NewAutomatic unpacking and Automatic packingIn Java SE5, in order to reduce the developer's work, Java provides automatic unpacking and auto-boxing capabilities.Automatic Boxing: The basic data type is automatically converted to the correspond
Automatic driving is regarded by the industry as the biggest challenge to the development of the next generation of vehicle technology, and all of them are currently developing corresponding technologies for automatic driving situations, which include the ability of environmental sensing, core computing, and how cars interact with the environment and determine their own decisions.

Optical Network is developing in the direction of high speed, large capacity, good expansibility and intellectualization. The appearance of automatic switched Optical Network is an important breakthrough of optical transmission network technology, and the enhancement of the function of optoelectronic devices will play a decisive role in its realization and development. This p

My implementation is in the Setup program to add an interface to allow users to set the automatic switching machine, this automatic switching machine settings can refer to the setting of the alarm clock. About the automatic shutdown, considering the shutdown, the user may be some important operations, then should give the user a chance to cancel
I. Precautions for automatic drive: Automatic Drive is also divided into sub-positions. Do not D to the end. Many people simply think that when an automatic car is opened, it's no big deal to move forward with the D Drive, reverse with the R drive, and stop with the p drive! But if it is really so simple, it is necessary to cancel all other driving positions of t

Not long ago, a friend asked small knitting, how to turn off automatic Updates, turn off automatic Updates what good way? He said that every time the system likes to automatically update, occupy a lot of memory, resulting in the work can not be completed, and each update after the production of a number of garbage files, the system has become slower than the original. In order for everyone to solve this pro
This is my first time to write more complex articles, the expression is not clear, please forgive me. Well, gossip less, come to the point.The most recent unit develops a project that requires the automatic upgrade feature. Because automatic upgrade is a more common function, may be used in many programs, so I want to write an automatic upgrade component, in the

Generally, the automatic transmission of an automatic transmission is divided into P, R, N, D, 2 (or S), L (or 1), and so on. The following describes in detail:
P (Parking) Parking range, or parking range:
P is used for parking. It uses mechanical devices to lock the rotating part of the car so that the car cannot move. When the engine
As people's living standard is more and more high, intelligent, automation equipment technology is more and more mature, integrated wiring system can resist external invasion and avoid external harm has become a new goal of attention. People increasingly rely on fire, but also more and more harm by fire, the comprehensive wiring system of fire safety has become the content of people's attention.
The external fire will destroy the integrated wiring system, cause transmission interrup
