Thank you, readers. I will still read the old writing to the old , and vivid image of the writing to experience. This is still a diagram , I study io this piece. the m

The first day of the new Year, for Programer, compared to the usual is not much different, the code is still knocking. Do a day of keyboard, not necessarily have any brilliant achievements (in fact, it seems to have been this/(ㄒoㄒ)/~~), but was once stuck in the problem again stumbled and then tangled to solve, by the way to review a bit. The problem is that the Struts2 tags and JSP's

Motivation automated testing makes testing repeatableJust like other

listed, not the cause. Write down all the symptoms that can be observed, whether it's exception handling or error code, even if it's just an abnormal behavior. You can use a text editor or Whiteboard, but it's important that you take notes on every step of the diagnostic process. Separate observations from assumptions help ensure that you do not exclude or ignore potential causes. And most of the time, listing more symptoms will narrow down the possi

PMD 5.7.0 was released. PMD is a Java program code checker that is released using the BSD protocol.

Check the java source code of the set data structure. You can see a question on the Internet: A set of strings. The format is as follows:. Merging a set whose intersection is not empty requires that there be no intersection between the merged sets. For example, the preceding example should be output. (1) Describe your solution to this problem; (2) provides the main processing procedures, algorithms, and

your own needs (before defining the template rule description below this page):After you submit your review, you can see the audit status of the template list and template below this page:Then click on "My Data" and click on "interface" in the SMS API service:The invocation instructions for the interface are all in this page and need to follow the rules here to invoke the API:After the SMS template application can use this API, the following shows ho

three rules, if you do something like this for the second time, you'll be tired of doing similar things, and the third time doing something like this is going to be reconstructed. (Charm, three refactoring).Refactoring is needed when we add new features, which can help us understand the previous code more deeply.Refactoring when we fix bugs can help us to better understand the code and find problems or bug

See a topic on the Internet:Given a collection of strings, in the formof:. Requires merging a collection where the intersection is not empty, requiring no overlap between the completed collections, for example, the above example should be output. (1) Please describe your idea of solving this problem; (2) give the main processing flow, algorithm, and the complexity of the algorithm; (3) Please describe the possible improvements. One solution is to use and check the set, (the

found that the problem should be String.charat () above, the code is as follows:public char charAt (int index) { if (Index There are two judgments that are very time-consuming, and we change to the following codeif (strs.length==0) return ""; String prefix =strs[0];for (int i = 1;ibecomes the 2ms, sure enough the problem is here, if we do not use the ToCharArray () method should be 1ms, which shows that our ideas and algorith
