book, I only talked about the Chandler to the "dog food" version, the version that the developers themselves used, and finally we didn't see the birth of the 1.0 version, not the final direction, but the difficulty of reading it. At the end of the paper, the author writes about the gambling about computer intelligence, which is also a prospect. At the same time still do not forget to remind the difficulty of making software-"the more you understand the software, the less you will do software."T

day to complete a quantitative task, and finally become a complete finished product. When I read this chapter, I found that I still for agile process this thing still half understand, I first say my understanding, I think agile process should be said to be based on the actual situation, sustainable, flexible way of cooperation. The process of agile process is just like the divide and conquer algorithm in our algorithm, the very big thing, cut it into a lot of small pieces, a big problem into a

8th ChapterWhat is the four-quadrant approach? How to use four-quadrant method to analyze the function of software in reality? Is the killer function a big part of the four-quadrant approach? The 9th chapter: Project ManagerIn order to become a qualified project manager, what to do well, what are the competencies?10th Chapter: Typical Users and scenariosShould a software meet a variety of users or focus on some kind of user? What should developers consider about the users and types of software s

cooperation is two people", two engineers look at the code and give their own opinions, so the code is extremely important, our code not only to let the machine to understand also need to read, in the fourth chapter of the study, we also try to write a program with others, the effect is quite good , the code allows us to read each other's program easily.In the fifth chapter, "Team and process" is associated with the "personal technology process" in chapter II, "The non-team and team" "Individua

day to practice shooting, do not be afraid of hard work, fun is in their mind to put a lot of attention when the sudden appearance, fun is the medicine of growth.Two people cooperateThe fourth chapter: after two people cooperation arithmetic realization, reading this chapter, I found that we want to have a common goal, although the road is different, but the direction to arrive consistent, there is code neat, easy to understand, because two people have different ideas, behavior, we write code n

before the fence must be completed before the fence, and any variable read after the masking must begin after the fence In a double lock, the initialization assignment using the user primitive object interlocked is unique, although it is a rare usage scenario, but it is worth noting. This is a volatile construct, and of course you can use the volatile keyword to solve the problem Strategies for lazy internal packaging None: No thread-safe hijacking at all (e.g. GUI application

the designation of a type argument and the inheritance hierarchy-understanding this can help you judge the transition.C # allows the use of simplified syntax to reference a generic enclosing typeusing Datetimelist = system.collections.generic.listNow that the following line of code is executed, Sametype is initialized to true:Boolean Sametype = (typeoftypeof(datetimelist));The CLR supports generic delegates to ensure that any type of object can be passed to a callback method in a type-safe mann

container.So you need to run under a server container such as Tomcat, and you can output dynamic pages, which results in the correct a option and the wrong B option. On the other hand, JSP is all called JavaServer pages, which literally means that a Java-language server-side page technology requires JDK support, so C and D are not.So both C and D are wrong.The Config object is an object that is created automatically when the server starts, and when the servlet is created, it is usually the info

to collection(Select an item) B: C: D: This topic examines how to get form content in a JSP. One of the hobbies is that you can choose multiple, you need to use the Getparametervalues method to get, the return value type is a string array. 50 A: B: C: D: 1 syntax for writing cookies:Response.addcookie (Cookname);Response.sendredirect ("Address");2 Read cookie information:Request.getcookies (); The correct answer is C, you're answ

correct answer is C,Redirection (Sendredirect) is initiated by the client browser, and the parameter in the request is lost. Note the difference between summary redirection (SENDREDIRECT) and forwarding (forward).(Select an item) A: B: C: D: The correct answer is C, and all JSPs are translated into the servlet's source code (Java) by the container after the client makes the request, and then the source (Java) is compiled into the servlet class, which is put into memory

correct answer is C,Redirection (Sendredirect) is initiated by the client browser, and the parameter in the request is lost.

syntax format is:Request.getattribute ("Myatr"); You can force type conversions Parsing: This topic examines how to display a variable on a JSP page. Note the B option, and you cannot add a semicolon at the end. Parse:response.sendredirect ("index2.jsp"); redirect, cannot get value in Request object, so output is null Parsing: This topic examines the understanding of the Response object set encoding, Response.setcontenttype ("Text/html;charset=utf-8"), which is set to encode a

/s programOut.println will not wrap, because this is in the JSP page, to wrap the line should be entered First, the JSP is essentially a servlet, in the background after the dynamic compilation of the final output to the client normal HTML code, so it needs to run in the Servlet container, and Tomcat is the server-side servlet container, so need to run under the server container such as Tomcat, and can output dynamic pages, resulting in a option is correct, the B option is wrong. On the other ha

original table of the change.>>> x = [1,2,3,47,3,2,5]>>> X.sort ()>>> x[1, 2, 2, 3, 3, 5, 47]>>>The sort method is highlighted below: Because he modifies the original list of data, I want a sort that does not modify the original list, to a list copy, is sorted well. How does this happen:>>> x = [1,2,3,47,3,2,5]>>> y = x[:]>>> y[1, 2, 3, 47, 3, 2, 5]>>> x[1, 2, 3, 47, 3, 2, 5]>>> Y.sort ()>>> y[1, 2, 2, 3, 3, 5, 47]>>> x[1, 2, 3, 47, 3, 2, 5]>>>It's a bit heavy. Rest summarized under. Continue l

Java beginners (Unit 7; Summary of the first six chapters), java Chapter 6 Chapter 1 Summary: 1. java is an advanced programming language launched by sun (Oracle Ltd.) in 1995. java technology can be applied to almost all types and sizes of devices, computer chips, cell phones, and super computers are everywhere. 2. java has become an absolute mainstream in the current software development industry. java SE and java EE in the java field have developed

"{" is usually placed at the bottom of the start line of this structure,"}" is aligned with the first letter of the institution and takes up a separate line.> A low-level statement or comment should be indented a few spaces after a statement or comment at a higher level, making the program moreClarity and increase the readability of the

number); Heap (a common memory pool, also in RAM, no longer need to be created before you know the specific life cycle, when an object is needed, When the program executes to new, the storage allocation in the heap is flexible, all of which may take longer to clean up the memory; the Stack (random access memory in general RAM, can be supported by a stack pointer, the pointer down is to add new memory, the pointer is free of memory , this is a quick way to allocate memory, second only to reg

addevent wraps the correct logical function, the code is as followsBut there is still one drawback to this function, assuming that we have not used the Addevent function from beginning to end.The third option is to use the lazy loading scheme, the first time you enter the conditional branch, the function will be overridden inside the function, the rewritten function is what we expect the Addevent function, the next time we enter the Addevent function, Addevent does not exist those branch judgme
