有没有简单的方法来避免处理文本编码问题？ You can't really avoid dealing with the text encoding issues, but there are existing solutions: Reader to InputStream : ReaderInputStream Writer to OutputStream : WriterOutputStream You just need to pick the encoding of your choice. 如果你从一个字符串开始，你也可以执行以下操作： new ByteArrayInputStream(inputString.getBytes("UTF-8")) Well, a Re
有没有简单的方法来避免处理文本编码问题？ 你不能真正避免处理文本编码问题，但现在有解决方案： Reader到InputStream ： ReaderInputStream Writer到OutputStream ： WriterOutputStream 你只需要选择你选择的编码。 如果你从一个字符串开始，你也可以执行以下操作： new ByteArrayInputStream(inputString.getBytes("UTF-8")) 那么，Reader会处理字符，InputStream会处理字节。 编码指定了如何将字符表示为字节，因
如何将String值转换为InputStreamReader ？ ByteArrayInputStream也有诀窍： InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) ); 我也发现了apache的commons IOUtils类，所以： InputStreamReader isr = new InputStreamReader(IOUtils.toInputStream(myString)); Does it have to be specifically an InputStreamReader? How about using StringReader? Otherwise, you could use StringBufferInp
如何将String值转换为InputStreamReader ？ ByteArrayInputStream也有诀窍： InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) ); 我也发现了apache的commons IOUtils类，所以： InputStreamReader isr = new InputStreamReader(IOUtils.toInputStream(myString)); 它是否必须专门用于InputStreamReader？ 如何使用StringReader？ 否则，你可以使用StringBufferInputStream，但由于字符转换问题而
Let's suppose I have just used a BufferedInputStream to read the bytes of a UTF-8 encoded text file into a byte array. I know that I can use the following routine to convert the bytes to a string, but is there a more efficient/smarter way of doing this than just iterating through the bytes and converting each one? public String openFileToString(byte[] _bytes) { String file_string = "";
假设我刚刚使用BufferedInputStream将UTF-8编码文本文件的字节读入字节数组。 我知道我可以使用下面的例程将字节转换为一个字符串，但是这样做是否有更高效/更智能的方式，而不仅仅是迭代字节并转换每个字节？ public String openFileToString(byte[] _bytes) { String file_string = ""; for(int i = 0; i < _bytes.length; i++) { file_string += (char)_bytes[i]; } return file_string;
This question already has an answer here: Read/convert an InputStream to a String 56 answers You can use this: BufferedReader reader = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8"))); String parseThis = reader.readLine(); That'll give you a string of the output. If it's in JSON, add: JSONObject jsonObj = new JSONObject(parseThis); JSONArray arr
这个问题在这里已经有了答案： 将InputStream读取/转换为字符串56个答案 你可以使用这个： BufferedReader reader = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8"))); String parseThis = reader.readLine(); 这会给你一串输出。 如果它在JSON中，请添加： JSONObject jsonObj = new JSONObject(parseThis); JSONArray arrayOfStuff = jsonObj.getJSONArray(array_tag);

This question already has an answer here: Read/convert an InputStream to a String 56 answers Consider the difference between your code: while (inputStream.read(reader) != -1) {} UserPassFile = new String(reader); And this alternative: while (inputStream.read(reader) != -1) { UserPassFile = new String(reader); } In your case, UserPassFile is ass
这个问题在这里已经有了答案： 将InputStream读取/转换为字符串56个答案 考虑你的代码之间的区别： while (inputStream.read(reader) != -1) {} UserPassFile = new String(reader); 而这个选择： while (inputStream.read(reader) != -1) { UserPassFile = new String(reader); } 在你的情况下，每次read（）调用后，UserPassFile都会从reader中分配，包括最后一次失败。
