Creates a new byte buffer by wrapping the given byte array.

Usage

From source file:Main.java

public static byte[] floatTobytes(float inFloat) {
    byte[] outBytes = new byte[4];
    ByteBuffer.wrap(outBytes).putFloat(inFloat);
    return outBytes;
}

public static String bytesToStringUTFNIO(byte[] bytes) {
    CharBuffer cBuffer = ByteBuffer.wrap(bytes).asCharBuffer();
    return cBuffer.toString();
}

From source file:Main.java

public static UUID getUuidFromByteArrayBigEndian(byte[] bytes) {
    ByteBuffer bb = ByteBuffer.wrap(bytes);

    long low = bb.getLong();
    UUID uuid = new UUID(high, low);
    return uuid;//from  w ww .  j  a  v a 2  s.  com
}
