Solve | The problem The way to solve the problem is: Change the bufferwriter to printwrite on it, wow, what's going on?? Did Bufferwriter and Bufferreader have a conflict? Bufferwriter cannot flush () and close () when Bufferreader is ReadLine ()? Weird The program is no problem, my data synchronization platform can also operate. public class Serverthread exte

Joseph Problem (detailed solution) and Joseph Problem SolutionPreface I learned the queue these days, so I tried Joseph Problem, And then I failed to get through it. Finally, after dialing, I passed. I am deeply impressed with the use of queues. We recommend that you try to solve this problem if the queue trainer is w

First look at a programming question: the string "I am Chinese man a better man" in reverse order to become "man better a man Chinese am I". Public class reversestring { publicstaticvoid main (String args[]) { = "I am a" Chinese man a better Man "; = Message.split (""); for (int i = array.length-1;i >= 0; i--) { System.out.print (Array[i]+ "");}}} steps and errors for problem resolution:1. Resolve the

1102-problem makes problemAs I am fond of making easier problems, I discovered a problem. Actually, the problem is ' what can you do n by adding k non-negative integers? ' I think a small example would make things clear. Suppose n=4and k=3. There is solutions. They is1.0 0 42.0 1 33.0 2 24.0 3 15.0 4 06.1 0 37.1 1 28.1 2 19.1 3 010.2 0 211.2 1 112.2 2 013.3 0 11

Feedback received on-site implementation: Now there is a system slow, the whole system stuck. Diagnostic process:1. Check the application log, that is, the WebLogic log, found a blocked thread, the code is called the interface2. Check the database report and find that the load is small, to infer that the problem is not at the database level today.3. Continue to analyze the code of the interface, discovering that the business is very easy, is to call a

Today in a sweep of the function, suddenly found several times to click on the sweep of the picture, resulting in a number of trigger taps gesture, on multiple push to the new page, I would like to tap gestures within the push to intercept, but also feel that if there are a lot of places to achieve the solution of the problem is not very troublesome? So think about it, we can solve this problem by rewriting

The problem was reported on the site recently. All electronic seal pages cannot be opened (in pdf format), and no errors were reported in background logs. The effect was blank: 1. First of all, I thought of the ocx control issue of the seal. I checked the ocx control installation and found that other computers could not open the document. On the test page, I can open the pdf document directly to eliminate the control issue. 2. I suspect there is a

First, we will introduce the biggest problem: Problem description: For an undirected graph G = (V, E), V is the vertex set, and E is the edge set. Then select several vertices in the vertex set. Any two vertices have edges in E. Find the maximum number of vertices that can be selected. These vertices constitute the largest group. Note: The largest group may not be unique.

One Parameter solves the webbrowser cache problem in the application In the past two days, when the webbrowser control is used in the application to load webpages, a problem occurs. When the same address and URL with the same parameters are repeatedly loaded, webbrowser will automatically load the local cache. In order to solve this problem, I read a lot of rela

reaction is the character set problem, because the MySQL character set has a number of parameters, and in the use of Chinese, the character set conversion will be affected by many character sets in cline,connection,server,table, so there are often some garbled situation.So we first check whether the data in the main library is written properly, and the result is normal. Then according to the following structure:cline--> master--> SlaveSince the main

This solution perfectly solves the problem that IE8 is not compatible with rgba (), and solves the problem that ie8 is not compatible with rgba Rgba () is a new property of css3, so IE8 and the following browsers are not compatible. What should I do? Finally, I found a solution. Solution Let's first explain the following rgba Rgba: The meaning of rgba. r indicates red, g indicates green, B Indicates bl

Virtual function-related problem analysis, function-Related Problem AnalysisZookeeper 1. Static Association and Dynamic AssociationThe function calls in the source code are interpreted as executing a specific function code block, which is called function name association. In C, this is very simple, because each function name corresponds to a different function. In C ++, this task is more complex due to func
