Boy, I'm absolutely in love with Java, but this question comes up so often you'd think they'd just figure out that the chaining of streams is somewhat difficult and either make helpers to create various combinations or rethink the whole thing. Bill K Nov 21 '08 at 17:16You are right. I tend to use a set of helper classes that do it once for me, so I don't need keep referring to Google or even StackOverflow for the answer. In this case, I was away from my utility code and couldn't remember exactly how to do it. What better way to open my account on the site. Johnny Maelstrom Nov 26 '08 at 11:21Yeah, it really shouldn't require so much boilerplate to do something as simple as read strings from a stream. It's not that difficult, just annoying. Adam Jaskiewicz Dec 8 '08 at 20:19@Adam: It really depends on what kind of Stream you're working with. For instance, System.console().readLine() (new in Java 6) is pretty easy. Same with BufferedReader's readLine(). The only hard part is when you don't know how many characters you need to read. Powerlord Dec 8 '08 at 20:46The answers to this question only work if you want to read the stream's contents fully (until it is closed). Since that is not always intended (http requests with a keep-alive connection won't be closed), these method calls block (not giving you the contents). f1sh Jul 14 '10 at 13:32You need to know and specify the character encoding for the stream, or you will have character encoding bugs, since you will be using a randomly chosen encoding depending on which machine/ope system/platform or version thereof your code is run on. That is, do not use methods that depend on the platform default encoding. Christoffer Dec 17 '10 at 13:50
I don't really know Java, but "InputStream is " seems wrong. Hello71 Feb 3 '11 at 0:50 @Hello71: It is ok in Java, since the instanceof operator is spelled differently. Roland Illig Apr 26 '11 at 17:13
@Ronald: Erm... never mind that. I must have been partially asleep while writing that. Hello71 Apr 26 '11 at 20:03i found filenotfound exception while i try to read file nam hope IOUtils takes an optional Charset (or at least the name of the encodding to use). Best not to leave this kind of thing to chance :) Jon Skeet Nov 21 '08 at 17:10 Harry Lime Nov 21 '08 at 17:11Why copy the inputstream to a writer? Why not just use a reader? Or read all bytes and use new String(bytes, charset)? Bart van Heukelom Oct 11 '10 at 22:27
81 You really, really, really should be using IOUtnputStream, writer, encoding); unless you really, really, really know what you're doing, which people never do with character encoding related programming. Or in this case, IOUtils.toString(inputStream, encoding). Methods that use the platform default encoding are almost never correct to use, like every other method that gives different results depending on which machine/ope system/platform or version thereof it is run on. Christoffer Hammaec 17 '10 at 13:45
I think the below answer (IOUtils.toString()) is simpler since there is no need for a StringWriter Patrick Feb 1 '11 at 23:5I don't know that I'd say the default encoding is NEVER fine. On the other hand, I disagree with Guillaume also. In fact, it's not a matter of fine or not; it's a matter of which is CORRECT. In the situation where you want to take something that you know is encoded in the default encoding for the platform, then the default version is correct. However, I believe this is a very rare use case. The more normal case is that you need to specify what the encoding is, so specifying the encoding is correct. There is no optional case: either one or (more likely) the other is correc
A quick but not clean solution. I would rather prefer a solution without adding additional libraries as mentioned in the post below MartinVonMartinsgrn Mar 1 '12 at 9:28Only works for closes streams, I believe. Thufir Aug 31 '13 at 2:01 i found filenotfound exception while i try to read file name with "_" file name(Russian language) i try with FileInputstream but it not cable to read this filename from sdcard. Bhanu Sharma Feb 11 at 5:39Can you guide me how to use this one? am little bit c
