correctly Javac/java, but not in EditPlus, Javac prompt "error: Accept the class name only when the annotation processing is explicitly requested." I also encountered this problem, carefully studied the discovery, the original is Java and Javac configuration confusion. The former configuration when the parameter is $ (filenamenoext) ignores the extension, and the latter is $ (FileName) using the full file name.Obviously, "Javac test" is not valid for source file Test.java, and "Java Test.class"

Everyone knows that C is faster than C ++ and C ++ is faster than C.The problem is the speed. The specific speed should not be general. What kind of operations should be faster, it is further divided into some special situations such as cold start, hot start, running, multi-run average, peak, and resource restriction. In these cases, we will test, analyze, and explain them here. Microsoft claims that. NET is about 90% of the execution efficiency of C

0 reply content: I think you wrote code using Notepad ++, saved it as a. py file, and double-click the file to execute it. In fact, Notepad ++ has many powerful functions, as long as you have patience to explore. Your problem can be solved as follows: 1. After writing the program, run F5 directly in Notepad ++. The following dialog box is displayed. 2. enter cmd/k x: cd "$ (CURRENT_DIRECTORY)" python "$ (FULL_CURRENT_PATH)" ECHO. PAUSE EX

This article addresses the following issues: Under Zend Studio inside the breakpoint and then debug Run (debug as PHP Web Application), but found that the site is running normally, the breakpoint is not effective at all. The breakpoint does not take effect, mainly because the debugger is not configured properly. In fact, Zend Studio has its own Zenddebugger debugger and is already integrated with the built-in PHP CLI environment. But to debug our own

giants. 1. Only one solution found on the Internet is to regenerate the solution (but I don't know why I didn't succeed, but people can succeed ). 2. delete the files in/bin/debug of the corresponding project and regenerate the project. Once this problem is solved, it will be recorded first. I have not found many related introductions on the Internet, but I am not clear about the descriptions. In fact, I am not very clear about the causes, I don't know why this problem occurs. I hope to help m
