, of course, git can also be restored through the historical version, but it is not easy to implement a partial restore.In short, the company's development team in the complex multi-project development, SVN is a better choice.Sign up: I found Git's website and followed http://www.aehyok.com/Blog/Detail/73.html and http://www.cnblogs.com/greyzeng/p/. The 5046776.html method is registered well. There is nothing to solve the problem, but still hope to launch the Chinese version of the ~Successful

Thinking logic of computer programs (49), thinking 49 Previously, we introduced two implementation classes HashMap and TreeMap of the Map interface. This section introduces another implementation class LinkedHashMap. It is a subclass of HashMap, but it can keep the elements sorted by insert or access, which is different from the TreeMap key sorting. It is easy to understand the order by insert.

extensions, the virus's authors use other extensions to break this protection. The executable file (. exe) is renamed. bat and. cmd, plus other extensions, and can still be run to successfully compromise the target user.Hackers often try to penetrate the Web to send an attachment like a flash image, and when the Flash demonstrates a compelling animation, it also runs commands in the background to steal your password, giving the decryption guru the opportunity to access your network.Reference an

A fact that violates intuitionThe computer is called "Computing" machine is because it is mainly used to calculate the invention, "calculation" of course is its expertise, in everyone's impression, the calculation must be very accurate. But in fact, even in some very basic decimal operations, the results of the calculations are imprecise.Like what: float F = 0.1f*0.1f; System.out.println (f);

bigger. For example, when you put data from a database into memory, you can use the SQL ORDER BY statement to have the database sort the data.Ordered by AccessLet's take a look at an orderly example with the following code:New true ); Accessmap.put ("C", [+]),accessmap.put ("D", "a"),Accessmap.put ("A", "a"); Accessmap.get ("C"); Accessmap.put ("D"); for (entry Entry:accessMap.entrySet ()) { System.out.println (Entry.getkey ()+ "" + Entry.getvalue ());}Each access moves the key-value pair t

from Google market, although the latter has proved to be feasible and can do well. From the discussion posts in the mobile developer community forum affiliated to mobile mm, we can find that there are a lot of developers who are actually married to mobile, and there are also a lot of dowry gifts, however, Mobile did not know what the purpose was. He detained the dowry and insisted that MM should go out and make appearances coldly. Therefore, we seem

Thinking logic of computer programs (45) and thinking 45 The previous sections introduced the basic container classes in Java. Each container class has a data structure behind it. ArrayList is a dynamic array, sorted list is a linked list, And HashMap/HashSet is a hash table, treeMap/TreeSet is a red-black tree. This section describes another data structure-heap. Introduce heap We mentioned heap before, whe

Thinking logic of computer programs (53), thinking 53 The previous sections introduced various specific container classes and abstract container classes. As we mentioned above, Java has a collection class that provides many common functions for container interfaces, these functions are provided in static mode. What functions are available? There are two possible

incompatible diagnostic programs, disk operating programs, performance testing programs, etc. are run to cause file loss and disk formatting. 4. computer viruses. Computer viruses can greatly interfere with and affect computer us

Thinking logic of computer programs (59) and thinking 59 The previous two sections show you how to read and write file content through a stream. This section describes operations on file metadata and directories. File and directory operations are ultimately related to the operating system and file system. The implementations of different systems are different, but Java. io. the File class provides a unified

Thinking logic of computer programs (39) and thinking 39 In the previous section, we introduced the ArrayList. the random access efficiency of ArrayList is very high, but the insertion and deletion performance is relatively low. We mentioned that the List interface's parallel List is also implemented, its features are almost the opposite of that of ArrayList. This section describes the feature list in detai

then sleeps for a while, then sets shutdown to true and finally outputs "exit main".The expected result is that all two threads exit, but actually executes, it is likely to be found that Hellothread never exits, that is, in the Hellothread execution flow, shutdown is always false, even if the main thread has changed to true.What's going on here? This is the memory visibility issue. In a computer system, in addition to memory, the data is also cached

Computer as one of our daily use equipment, once the occurrence of such a fault, we can imagine the trouble, especially some rookie friends, once the failure of the hands of the work can not be completed on time, their own blind toss and fear of damage to the hardware equipment, maintenance and bear economic losses. In fact, we do not have so much trouble, computer problems are often a small number of glitc

Thinking logic of computer programs (74) and thinking 74 This section describes a commonly used concurrent container-ConcurrentHashMap, which is a concurrent version of HashMap. Compared with HashMap, it has the following features: Concurrency Security Directly supports atomic composite operations Supports high concurrency, fully parallel read operations, and parallel write operations to a certain exten

Thinking logic of computer programs (58) and thinking 58 In the previous section, we introduced how to process files in byte streams. we mentioned that for text files, byte streams do not have the encoding concept and cannot be processed by row, which is inconvenient to use, it is more suitable to use the streaming. This section describes the streaming. First, we will briefly introduce the basic concepts of
