Description

The list of methods to do ByteBuffer to String are organized into topic(s).

Method

StringtoString(ByteBuffer buffer)
Convert the buffer to an ISO-8859-1 String 
return toString(buffer, StandardCharsets.ISO_8859_1);
StringtoString(ByteBuffer buffer)
to String 
StringBuffer response = new StringBuffer();
Charset charset = Charset.forName("UTF-8");
response.append(charset.decode(buffer));
buffer.flip();
return response.toString();
StringtoString(ByteBuffer buffer)
to String 
StringBuffer response = new StringBuffer();
Charset charset = Charset.forName("UTF-8");
response.append(charset.decode(buffer));
buffer.flip();
return response.toString();
StringtoString(ByteBuffer buffer)
Converts the contents of the specified byte buffer to a string, which is formatted similarly to the output of the Arrays#toString() method. 
StringBuilder builder = new StringBuilder("[");
for (int i = 0; i < buffer.limit(); i++) {
    String hex = Integer.toHexString(buffer.get(i) & 0xFF).toUpperCase();
    if (hex.length() == 1)
        hex = "0" + hex;
    builder.append("0x").append(hex);
    if (i != buffer.limit() - 1) {
        builder.append(", ");
...
StringtoString(ByteBuffer buffer)
to String 
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
return new String(bytes, "utf-8");
StringtoString(ByteBuffer buffer)
Convert the ByteBuffer to a UTF-8 String. 
if (buffer == null)
    return null;
byte[] array = buffer.hasArray() ? buffer.array() : null;
if (array == null) {
    byte[] to = new byte[buffer.remaining()];
    buffer.slice().get(to);
    return new String(to, 0, to.length, StandardCharsets.UTF_8);
return new String(array, buffer.arrayOffset() + buffer.position(), buffer.remaining(),
        StandardCharsets.UTF_8);
StringtoString(ByteBuffer buffer, Charset charset)
to String 
buffer = buffer.slice();
byte[] buf = new byte[buffer.remaining()];
buffer.get(buf);
return new String(buf, charset);
StringtoString(ByteBuffer buffer, int offset, int length)
Constructs a new String by decoding the specified subarray of bytes using the ASCII charset. 
if (offset < 0 || length < 0 || offset + length > buffer.limit()) {
    throw new IndexOutOfBoundsException();
int position = buffer.position();
int limit = buffer.limit();
buffer.position(offset);
buffer.limit(offset + length);
String result = StandardCharsets.US_ASCII.decode(buffer).toString();
...
StringtoString(ByteBuffer buffer, String encoding)
to String 
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
return fromBytes(bytes, encoding);
StringtoString(ByteBuffer bytes)
Parses a string out of a byte buffer whose content is UTF-8 encoded. 
return toString(toByteArray(bytes));
