buffered

问题 Program freezes when closing buffered reader. Using forge modding API for minecraft, however I've had this issue before with standalone server side code. This particular code worked fine and then randomly started giving me this issue, not sure how to go about fixing this.. The close method: public static void closeConnection() { if (keepConnection) { keepConnection = false; try { bufferedReader.close(); printWriter.close(); socket.close(); } catch (IOException e) { e.printStackTrace(); }

问题 I am sorry if this is a duplicate but I was not able to find a definitive answer to what is the best practice for each type. I would like to know what the appropriate conditions are that define when to use BufferedReader vs FileReader or BufferedInput/OutputStream vs FileInput/OutputStream? Is there a formula of sorts that will always tell you what is appropriate? Should I just always used buffered? Thanks 回答1: Use a buffer if the stream is going to have lots of small access. Use unbuffered

问题 (apologies for the somewhat lengthy intro) During development of an application which prefaults an entire large file (>400MB) into the buffer cache for speeding up the actual run later, I tested whether reading 4MB at a time still had any noticeable benefits over reading only 1MB chunks at a time. Surprisingly, the smaller requests actually turned out to be faster. This seemed counter-intuitive, so I ran a more extensive test. The buffer cache was purged before running the tests (just for

问题 Section 7.9.13/7 of c99 states that: At program start-up, three text streams are predefined and need not be opened explicitly - standard input (for reading conventional input), standard output (for writing conventional output), and standard error (for writing diagnostic output). As initially opened, the standard error stream is not fully buffered; the standard input and standard output streams are fully buffered if and only if the stream can be determined not to refer to an interactive device

问题 I can't figure out a way to get smooth movement or animation of anything using Java2d when the opengl and direct3d pipelines are disabled (by invoking the vm with -Dsun.java2d.d3d=false and -Dsun.java2d.opengl=false) The quick and dirty code below demonstrates my problem. It draws a box that moves across the screen. The box location is updated about 60 times per second and the screen is redrawn as many times as possible. It uses the BufferStrategy class to implement double buffering; the flip

问题 I am using buffered reader to grab a line at a time from a text file. I am trying to also get the line number from the text file using a tracking integer. Unfortunately BufferedReader is skipping empty lines (ones with just /n or the carriage return). Is there a better way to solve this? Would using scanner work? Example code: int lineNumber = 0; while ((s = br.readLine()) != null) { this.charSequence.add(s, ++lineNumber); } 回答1: I could not reproduce your claim that BufferedReader skips

问题 I have a log file which gets updated every second. I need to read the log file periodically, and once I do a read, I need to store the file pointer position at the end of the last line I read and in the next periodic read I should start from that point. Currently, I am using a random access file in Java and using the getFilePointer() method to get he offset value and the seek() method to go to the offset position. However, I have read in most articles and even the Java doc recommendations to

问题 I've been using Xcode for 2 years and have written quite a few C++ command line applications. For the past few months, I've abandoned command line applications and have focused on GUI applications, but after coming back to some older command line applications, I noticed that std::cout isn't working the way I last remember. If I have a cout statement such as "enter age: " before a cin statement, when running the app in Xcode, it no longer shows the cout statement first, but rather after the
