5. BufferedReader forums.oracle.comWhat does this have to do with buffered readers? Like I told you before, problems aren't always related to whatever you happen to be doing when you encounter them. Why does this matter? Because it means you're not thinking about the problem rationally, so you're less likely to be able to solve it. |

8. BufferedReader skips doubles, reads them as Strings? forums.oracle.comHaha, you are correct. I'm used to Python's scripting magic and I end up doing very stupid stuff when doing "real" programming. Nevertheless, it's still a weird bug. I'll mess with it some other day. Thanks though. I appreciate your help and time and I'll edit this post if I find the solution. |

19. BufferedReader Question forums.oracle.comYour code will never throw EOFException so the catch is in fact pointless. I'm prepared to bet the file contains 3k lines, not 5k. Or else you are reading another line somewhere. Just read until readLine() returns null, forget the count. How are you ever going to keep the count up to date with the file? |
20. BufferedReader instance necessary? forums.oracle.comYou still need to close the BR. First, you don't know when, or even if, it will be GCed. Second, you don't know if it will release the file handle when it is GCed. GC is only for releasing memory, not other system resources. Although some other resources may happen to get released as part of GC in some circumstances, you ... |
21. Why do we need BufferedReader forums.oracle.coma question just out of interest, but the buffering is only useful when you read data in small chunks (like byte for byte), isn't it? If for example you read a stream in chunks of say 4k, I'd hazard a guess that buffering isn't going to help much in the performance department. I never tested that really. |
22. Bufferedreader close() forums.oracle.comIt sounds like a bad idea to ignore the contents of a stream just because your program is taking too long to run. Why can't you let the program run to completion naturally? If you're worried about the user experience you could notify them that something is actually happening (e.g.a progress bar, or a dialog). |

25. BufferedReader problems forums.oracle.comYou get a greater chance of help, faster, if you can prepare an [SSCCE|http://pscode.org/sscce.html] that demonstrates the behavior.

26. Problem with "BufferedReader.ready()" forums.oracle.comDon't use ready(). It is a silly method with very few (if any) legitimate uses. What, you are trying to write a program that sits in a tight buzz loop printing "NOT READY" a zillion times a second? Just don't do that. Just read a line; when one is available your program will process that line; until the line is available, ... |

49. Stream Closed BufferedReader in Java forums.oracle.com} //The input file contains around 2000 line with 80 chars each. And when it reads 102 lines from the buffer, it reads only 11 chars.

52. BufferedReader methods forums.oracle.comHowever, the other posters are right, this is a bit strange, because it's not very efficient nor is it very scalable.

54. BufferedReader converts "..." into question mark forums.oracle.comWell, strictly speaking no file containing a "..." character is an ASCII file because there's no representation of "..." in ascii (except three separate dots). So your file is in some encoding with a code for "...". What you need to discover is, which encoding. Of course it's possible the program is reading the ... correctly but is unable to output ... |
