unknown class object in the event-handling thread class, the thread object is only responsible for running the processing method when it is useful.You can download kylib:http://download.csdn.net/source/1538376 and use a lot of event method pointers in the Kylib class library, so you can refer to learning. Actually is the class method pointer, I think your method is not easy to use, although the principle i

"Use strict"; When placed in the starting position of a JavaScript file or function (I am not sure if the script tag can begin), you can turn on strict mode. Otherwise-in the case of a JavaScript file that is not at the beginning of the file and not at the beginning of the function-it is a generic string that is not used, except that it wastes a few bytes and is of little use. It is generally recommended to

, or difficult to use correctly. So developers often use the wrong. A little better for Unicode support. These languages appear only after Unicode is widely prevalent, but the way Unicode is manipulated in languages is a serious error. Although these languages are born later, they still contain all the shortcomings of the first language. In my experience, one of the languages represented is PHP. Althoug

Reprint: http://www.ibm.com/developerworks/cn/java/j-jtp06197.htmlThe Java™ language contains two intrinsic synchronization mechanisms: synchronous blocks (or methods) and volatile variables. Both of these mechanisms are proposed to achieve the security of code threads. Where volatile variables are less synchronous (but sometimes simpler and less expensive), and their use is more error-prone. In this period of Java theory and Practice , Brian Goetz wi

But in order to show the richness of the sunrise cloud, we chose the brightest point in the sky as the white balance correction point to try to restore the color of the clouds. After choosing a good point, use the eyedropper tool in the color adjustment, move to the point you choose, click Down to change the white balance. In addition, you can also

, useVolatile is not enough to implement counters, mutex locks, or any class (such as "Start For simplicity or scalability, you may prefer to use volatile variables instead of locks. When usingWhen the volatile variable is not locked, some usage (idiom) is easier to code and read. In addition, volatileVariables do not cause thread blocking like locks, so they rarely cause scalability problems. In some cases, if the read operation is much larger than t

variable Volatile variables have the visibility of synchronized, but do not have atomic properties. This means that the thread can automatically discover the latest value of the volatile variable. Volatile variables can be used to provide thread security, but can only be used in a very limited set of Use Cases: There is no constraint between multiple variables or between the current value of a variable and the modified value of a variable. Therefore,

. On most platforms, the default is ASCII encoding. But for all conversions, using this encoding is almost always wrong. Call str () or One solution to this Unicode dilemma is that the call sys.setdefaultencoding() sets the default encoding to the code that will actually be used. But it just hides the problem, although it's just beginning to solve some text processing problems. But there is a lack of practicality, because many applications, especially Web applications,

For a long time, there has been a lot of controversy about how to use the volatile correctly, even some experienced Java designers, the understanding of volatile and multithreaded programming is still mistaken. In fact, the use of volatile is very simple, as long as the understanding of the Java memory model and the basic knowledge of multithreaded programming, the corr
