Java Utililty Methods ByteBuffer from String

ByteBuffer asByteBuffer(String data)
as Byte Buffer

try {
 return ByteBuffer.wrap(data.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
 throw new UnsupportedOperationException(e);

ByteBuffer asByteBuffer(String s)
as Byte Buffer

if (null == s) {
 return null;
if (s.length() < 1024) { 
 return isASCII(s) ? US_ASCII.encode(s) : UTF_8.encode(s);
} else {
 return UTF_8.encode(s);

ByteBuffer stringToByteBuffer(String data)
string To Byte Buffer

return ByteBuffer.wrap(data.getBytes());

ByteBuffer stringToByteBuffer(String string)
string To Byte Buffer

ByteBuffer bb = null;
try {
 bb = ByteBuffer.wrap(string.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
 e.printStackTrace();
 throw new Error();
return bb;
...

ByteBuffer stringToNullTerminatedByteBuffer(String s)
Converts a String into a direct ByteBuffer, after adding a null character at the end of the String

int len = s.length() + 1;
ByteBuffer buf = directByteBuffer(len);
buf.put(s.getBytes());
buf.put((byte) 0);
buf.flip();
return buf;

ByteBuffer toByteBuffer(final String s)
Converts a string into bytes in the UTF-8 character set.

return DEFAULT_CHARSET.encode(CharBuffer.wrap(s));

ByteBuffer toByteBuffer(String hexStr)
to Byte Buffer

if (hexStr == null || hexStr.length() == 0) {
 return null;
if (hexStr.length() % 2 != 0) {
 throw new IllegalArgumentException("Invalid hex value.");
byte[] ba = new byte[hexStr.length() / 2];
for (int i = 0; i < ba.length; i++) {
...

ByteBuffer toByteBuffer(String s)
Converts the given String into a 0-terminated, direct byte buffer.

byte bytes[] = s.getBytes();
ByteBuffer buffer = createByteBuffer(bytes.length + 1);
buffer.put(bytes);
buffer.put((byte) 0);
buffer.rewind();
return buffer;

ByteBuffer toByteBuffer(String value)
Convert the given String to a byte[] value using UTF-8 and wrap in a ByteBuffer.

return ByteBuffer.wrap(toBytes(value));

ByteBuffer toByteBuffer(String value)
to Byte Buffer

return ByteBuffer.wrap(value.getBytes("utf-8"));
