the constant pool in Java is actually divided into two forms: a static constant pool and a run-time pool. The so-called static constant pool, the constant pool in the *.class file, is a constant pool in a class file that contains not only string literals, but also classes, methods, and most of the space in the class file. running a constant pool is a JVM virtual machine that, after completing the class mount operation, loads the constant pool in class file into memory and saves it in the method

Unity3D game development: quickly creating a popular level system, unity3d Game Development Dear friends, welcome to my blog. I am Qin Yuanpei and my blog address is blog.csdn.net/qinyuanpei.Today I want to share with you the more popular checkpoints on mobile platforms, the level system is usually used for stand-alone mobile games, such as Angry Birds and defending radish, to organize the game content, players can obtain scores through the unlocked

In Python, it is the lowest level of synchronization primitives currently available and is implemented directly through the _thread extension module.Ther

I want to unlock it? You cannot modify the computer's operating system (Windows XP). Because the control is in the CDMA card, you must try to modify the system on the CDMA card through Windows XP, in order to achieve the purpose of unlocking. 2. Some people may ask, what is perfect unlocking? What is not perfect for unlocking now? A perfect unlock is a real unlock. If your iPhone is unlocked perfectly, your iPhone does not need any baseband firmware

A log of a table S8, a record of each item, to be associated with a commodity table. But the association has encountered the problem of tilt. The

constant pool, if any, returns a reference to the string, and if not, adds its own string into the constant pool.the benefits of a constant poolChang is to avoid the frequent creation and destruction of objects and affect the performance of the system, which realizes the sharing of objects.For example, a string constant pool in which all string literals are placed in a constant pool during the compilation phase.(1) Save memory Space: All the same string constants in a constant pool are merged,

But the connection has a skewed problem. 32 of the S8 log has a string commodity ID and a numeric commodity ID, and the type in the log is string, but the value ID in the product is bigint. The reason for guessing the problem is that the S8 's product ID is convert

specified when the lock is created, and in the linuxthreads implementation there is only one lock type attribute __mutexkind, and the different lock types behave differently when attempting to lock an already locked mutex, that is, whether to block the wait. There are three values to choose from: · PTHREAD_MUTEX_TIMED_NP, this is the default value (direct write null is the default value), that is, the normal lock (or fast lock). When a line is Cheng, the remaining thread that requests the lock

next fetch or the cursor closes, whichever occurs first. The next time the fetch occurs, the server acquires a scroll lock for the row in the new fetch and releases the last scroll lock to fetch rows. A scroll lock is independent of the transaction lock and can be persisted after a commit or rollback operation. If the option to close the cursor at commit is off, the commit statement does not close any open cursors, and the scroll lock is persisted to the commit to maintain isolation of the extr

status. Therefore, using a state machine is a good choice. The game engine is one of the most successful applications of finite state machines, because well-designed state machines can be used to replace part of artificial intelligence.AlgorithmTherefore, each role or device in the game may be embedded with a state machine. Consider a simple object such as the gate in RPG games. It has four states: open, closed, locked, and unlocked, as shown in 1.
