サイズエンドモードのintとbyteの相互変換

今日はここでintとbyteタイプ変換のまとめをします.コードを直接添付します.この年はこんなにさっぱりしなければならない.

/**
 *  int byte[]
 */
public static byte[] intToBytesBig(int value) {
    byte[] src = new byte[4];
    src[0] = (byte) ((value >> 24) & 0xFF);
    src[1] = (byte) ((value >> 16) & 0xFF);
    src[2] = (byte) ((value >> 8) & 0xFF);
    src[3] = (byte) (value & 0xFF);
    return src;
}

/**
 *  int byte[]
 *
 * @param value
 * @return
 */
public static byte[] intToBytesLittle(int value) {
    byte[] src = new byte[4];
    src[3] = (byte) ((value >> 24) & 0xFF);
    src[2] = (byte) ((value >> 16) & 0xFF);
    src[1] = (byte) ((value >> 8) & 0xFF);
    src[0] = (byte) (value & 0xFF);
    return src;
}

/**
 *  byte[] int
 */
public static int bytesToIntBig(byte[] src, int offset) {
    int value;
    value = (int) (((src[offset] & 0xFF) << 24)
            | ((src[offset + 1] & 0xFF) << 16)
            | ((src[offset + 2] & 0xFF) << 8)
            | (src[offset + 3] & 0xFF));
    return value;
}

/**
 *  byte[] int
 */
public static int bytesToIntLittle(byte[] src, int offset) {
    int value;
    value = (int) ((src[offset] & 0xFF)
            | ((src[offset + 1] & 0xFF) << 8)
            | ((src[offset + 2] & 0xFF) << 16)
            | ((src[offset + 3] & 0xFF) << 24));
    return value;
}
