2015-01-14has been planning to learn Java, tonight finally determined to see the next Preach Intelligence podcast Park Teacher's javaweb development video DAY01 First, the main content is the development of simple introduction of tools, how to create engineering, JUnit Introduction, I was born in C #, all checked into the seat.1.JDK = =. Net Frameworkare basic libraries, but Java development tools are introduced manually, like DLL introduction2.Conten

In this, really thank the Zhang Xiaoxiang podcast teacher, although has left, but still want to thank. Multithreading this piece helps a lot. (Watch a video of public lessons)In general, I can write a single-threaded version of the program, but it is important to consider clearly, will be a race condition of the resources written into the same class.Then consider if there is a race condition, then add synchronized if you need to keep synchronous commu

A set of ERP system will have CRM, it is impossible to say that all my data are scattered, you want to use just write one. You go out and talk to people, you must say I have something here, and then you can tell people you do is invoicing. Ask the CRM or the financial system you say it's not my responsibility. If you've ever been in touch with a similar system, you can say that I've also done CRM, so to speak. We connect directly to the existing financial system, and you just push it out and you

month, the price should be in what paragraph. Suddenly its price is very low, the system thinks this time is more suitable for purchase. Is the price very low when must buy? You'll have to watch your inventory. The same is true for sales, and we've already estimated that this product will have a big gain by September, and it's going to have a big gain by September. This year also should have, even if it is not up to the highest, according to the year, the first annual increase of 2%, the second

The reason why the wild pointer is produced:1, the pointer variable and the memory space variable that he points to are two different concepts2, although the call to the free (p) method frees the memory space pointed to by the pointer, but the pointer variable is not reset to null3, resulting in the freed of the pointed memory space, the use if (p! = NULL) is also executed, and the free () method is executedAvoidance methods:1, when the pointer is defined, initializes its value to null (char *p

The function of the application memory space in the C language malloc ()char *p = NULL;p = (char *) malloc (sizeof (char) * 100);The meaning of the above code is:Defines a char-type pointer pAllocate size to the memory space pointed by the pointer p through the MALLOC functionP is the memory addresssizeof is the number of bytes occupied by getting char, typically 4 bytesThe malloc function is the void* function (void * __cdecl malloc (_in_ _crt_guardoverflow size_t _size);)So to force the defini

code in the red area? It's not a good idea. Do you not know which object to pass in? What's the new object? Then consulted the developer sitting next to my colleague, finally figured out that the reflection is not so used, the above code can not be used to write the reflection code. The real reflection usage is this:Class Clazz=class.forname ("Com.learn.reflect.Person");--first or load the target classObject obj=clazz.newinstence;Method M=clazz.getmethod ("Print3", String[].class); --string[].c

Enterprises cannot use the workflow technology in development, such as the entry approval process in the human resource management system, the contract approval process in the Contract Management System, the leave approval process in the OA, And the reimbursement process in the financial management system. Workflow module development is also one of the most technically difficult modules in enterprise management system development. net to train the technical strength of students. net training cou
