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

Method

byte[]toByteArrayFromInt(int intValue, boolean shortSize)
Converts an integer (which in Java is a signed four bytes value) into a byte array 
byte[] tempArr = ByteBuffer.allocate(4).putInt(intValue).array();
byte[] retArr;
if (shortSize) {
    retArr = ByteBuffer.allocate(2).put(tempArr, 2, 2).array();
} else {
    retArr = tempArr;
return retArr;
...
byte[]toByteArrayFromLong(long longValue)
Converts a long (which in Java is a signed eight bytes value) into a byte array 
return ByteBuffer.allocate(8).putLong(longValue).array();
byte[]toBytes(BigDecimal number, int byteLength)
to Bytes 
return toBytes(number.unscaledValue(), byteLength);
byte[]toBytes(char[] ch)
Converts a char array to a byte array. 
return toBytes(ch, Charset.defaultCharset());
byte[]toBytes(char[] chars)
to Bytes 
CharBuffer cf = CharBuffer.wrap(chars);
ByteBuffer bf = CHARSET.encode(cf);
return bf.array();
byte[]toBytes(char[] string)
to Bytes 
CharBuffer charBuffer = CharBuffer.wrap(string);
ByteBuffer byteBuffer = Charset.forName("UTF-8").encode(charBuffer);
byte[] bytes = Arrays.copyOfRange(byteBuffer.array(), byteBuffer.position(), byteBuffer.limit());
Arrays.fill(charBuffer.array(), '\u0000');
Arrays.fill(byteBuffer.array(), (byte) 0);
return bytes;
byte[]toBytes(final float val)
Convert a float value to a byte array 
ByteBuffer bb = ByteBuffer.allocate(SIZEOF_FLOAT);
bb.putFloat(val);
return bb.array();
byte[]toBytes(final UUID uuid)
to Bytes 
return ByteBuffer.allocate(Integer.SIZE).putInt(uuid.hashCode()).array();
byte[]toBytes(InputStream input)
Converts an Input Stream to byte[] 
if (input == null)
    return null;
try {
    ByteArrayOutputStream output = new ByteArrayOutputStream();
    byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
    int n = 0;
    int count = -1;
    while (EOF != (n = input.read(buffer))) {
...
byte[]toBytes(int value)
to Bytes 
ByteBuffer buffer = ByteBuffer.allocate(4);
buffer.putInt(value).flip();
return readBytes(buffer, 4);
