Quite interesting. What does the channel means. I know that is to avoid block the "thread?" They can be bidirectional ( or that's what I understood ) But, in more simple word, what are they? Can you elaborate In many ways, a ReadableByteChannel is like an InputStream, and WritableByteChannel is like an OutputStream. Many concrete Channels implement both of these interfaces, so one object is bi-directional. Some channels (SocketChannel) support non-blocking IO, but this isn't true of all channels. erickson Nov 28 '08 at 19:11
Do you know the time- and memory-efficiencies of this idiom, or can at least estimate? It's a beautiful idiom! Technically speaking, it's O(n) in time and space. Qualitatively, due the immutability requirement of Strings, it's pretty hard on memory; temporarily there are two copies of the char data in memory, plus the room for the encoded bytes. Assuming some single-byte encoding, it will (temporarily) require 5 bytes of memory for each character in the file. Since the question asks specifically for a String, that's what I show, but if you can work with the CharBuffer returned by "decode", the memory requirement is much less. Time-wise, I don't think you'll find anything faster in the core Java libs. Possible typo? NIO has a Charset (not CharSet) class c Is this what CharSet should have been? Jonathan Wright : after exercising a bit that code, I found out that you can't reliably delete the file right after reading it with this method, which may be a non issue in some case, but not mine. May it be in relation with this issue ? I finally went with the proposition of Jon Skeet which doesn't suffer from this bug. Anyways, I just wanted to give the info, for other people, just in case...

Your philosophy has a bad understanding of exceptions. Most people think exceptions means holy-crap-out-of-doom-something's-wrong-die-die-die. When exception means.... exception. It means something exceptional occurred that you need to "handle" (or account for). Maybe you want to keep retrying for data access, maybe the user needs to know that you can't get a connection. What do you do? You handle the ConnectionFailedException and notify the user, so maybe, they'll stop trying after an hour, and notice the cable is unplugged. Lee Louviere Mar 11 '13 at 15:28
I tried reading an exe file using this method with default charset, append some data in it and again make it an exe, But it corrupted the exe, Any thoughts ? smilepleeeaz Sep 13 '13 at 7:21
@smilepleeeaz What you describe makes no sense. EXE files are not text. And they have a well-defined structure. First you are destroying the content of the file by decoding it as text, then you are destroying the structure by appending text to it. How could this fail to corrupt the EXE? erickson Sep 13 '13 at 15:20
I don't really care about encoding, could I just use Charset.defaultCharset() instead of having an argument accepting it? jcz Jan 11 at 21:22

@yannbane If you are sure that the file will always be encoded with the platform's default character set, yes, you could do that. If there's a mismatch, then you'll care about encoding. erickson Jan 11 at 23:25

try {
byte[] bytes = Files.readAllBytes(f.toPath());
return new String(bytes,"UTF-8");
