Usage

From source file:ConversionUtil.java

public static byte[] convertToByteArray(short value) {

    byte[] bytes = new byte[2];
    ByteBuffer buffer = ByteBuffer.allocate(bytes.length);
    buffer.putShort(value);
    return buffer.array();
    // buffer.get(bytes);
    /*/*from  w w w . j ava  2s  .c  o  m*/
    for (int i =0;i<bytes.length; ++i) {
    int offset = (bytes.length -i-1) *8;
    bytes[i] = (byte)((value & (0xff << offset)) >>> offset);
    }
     */
    // return bytes;
