Method

StringinputstreamToString(InputStream input, CharsetDecoder decoder)
Reads an input stream into a string. 
CharsetDecoder charsetDecoder = decoder;
if (decoder == null) {
    charsetDecoder = Charset.defaultCharset().newDecoder();
BufferedReader reader = new BufferedReader(new InputStreamReader(input, charsetDecoder));
StringBuilder stringBuffer = new StringBuilder();
String line = reader.readLine();
while (line != null) {
...
StringinputStreamToString(InputStream inputStream, Charset charset)
Convert an InputStream into a String. 
if (inputStream != null && inputStream.available() != -1) {
    ByteArrayOutputStream result = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length;
    while ((length = inputStream.read(buffer)) != -1) {
        result.write(buffer, 0, length);
    if (charset != null) {
...
StringinputStreamToString(InputStream inputStream, String charset)
input Stream To String 
return inputStreamToString(inputStream, Charset.forName(charset));
StringinputStreamToString(InputStream is, Charset charset)
input Stream To String 
if (is == null) {
    throw new IllegalArgumentException("input stream MUST NOT be null");
if (charset == null) {
    throw new IllegalArgumentException("charset MUST NOT be null");
ByteArrayOutputStream result = new ByteArrayOutputStream();

booleanisCharsetMisInterpreted(String input, String encoding)
is Charset Mis Interpreted 
CharsetDecoder decoder = Charset.forName("ascii").newDecoder();
CharsetEncoder encoder = Charset.forName(encoding).newEncoder();

Streamlines(InputStream in, Charset cs)
Read all lines lazily from an InputStream as a Stream . 
InputStreamReader reader = new InputStreamReader(in, cs);
BufferedReader br = new BufferedReader(reader);
try {
    return br.lines().onClose(asUncheckedRunnable(br));
} catch (Error | RuntimeException e) {

    while ((ch = reader.read()) >= 0) {
...
booleanprocessSubstitute(CharBuffer cb, String replacement, boolean endOfInput, String outputCharset, OutputStream os)
Scan the characters in the buffer and do replacement. 
int remaining = cb.remaining();
if (remaining == 0) {
    cb.clear();
    return false;
String result = SEARCH_PATTERN.matcher(cb).replaceFirst(replacement);
cb.clear();

Stringstream2Bytes(InputStream is, Charset charset)
stream Bytes

    result = new String(bs, charset.name());
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
...
StringstreamString(InputStream in, boolean closeIn, String charset)
stream String 
return new String(streamBytes(in, closeIn), Charset.forName(charset));
