I have an event processing scheme which should also eventually write to file; I cannot afford to delay the event when the file is being flushed, i.e. waiting to the end of BufferedWriter.write(String). I'm looking for the easiest way to achieve that (is there's a library doing that? I reckon that I'm not the only one who had this proble...
I'm working on an assignment, and have completed the code, however I am having an issue with correct formatting of the output.

I was expecting the following code to throw an exception when I goto write data to the Stream: File file = new File("test.txt"); FileOutputStream fs = new FileOutputStream(file); OutputStreamWriter ow = new OutputStreamWriter(fs); BufferedWriter writer = new BufferedWriter(ow); fs.close(); try { ow.write(65); writer.write("tes...
In my chat app, I am adding the ability to log chats. The logs are saved on the sdcard and one BufferedWriter is kept open for every person/channel chat is done with. I'm wondering what effects this might have have on the sdcard and its life. My BufferedWriter's buffer size is to 1024, I'm also wondering if that is too small or too big....

I want to know if close() waits for the system call to complete its operation or does i...

The Javadoc for this says: Only the lower two bytes of the integer oneChar are written. What effect, if any, does this have on writing non-utf8 encoded chars which have been cast to an int? Update: The code in question receives data from a socket and writes it to a file. (A lot of things happen between receiving and writing, so I can...
