发一个JAVA将小端序转大端序的代码块。。。

public static short LowToShort(short a) {
    return (short)(((a & 0xFF) << 8) | ((a >> 8) & 0xFF));
}
public static int LowToInt(int a) {
    return (((a & 0xFF) << 24) | (((a >>8) & 0xFF) << 16) | (((a >> 16) & 0xFF) << 8) | ((a >> 24) & 0xFF));
}

 

	public static short LowToShort(short a) {
		return (short) (((a & 0xFF) << 8) | ((a >> 8) & 0xFF));
	}
	public static int LowToInt(int a) {
		return (((a & 0xFF) << 24) | (((a >> 8) & 0xFF) << 16) | (((a >> 16) & 0xFF) << 8) | ((a >> 24) & 0xFF));
	}

另外2个整型的方法

	public static void printLittleEndian(int i) {
		byte[] b = new byte[4];
		b[0] = (byte) (0xff & i);
		b[1] = (byte) ((0xff00 & i) >> 8);
		b[2] = (byte) ((0xff0000 & i) >> 16);
		b[3] = (byte) ((0xff000000 & i) >> 24);
		for (byte c : b) {
			System.out.print("0x" + Integer.toHexString(c & 0xFF) + ",");
		}
		System.out.println();
	}
	public static void printBigEndian(int i) {
		byte[] b = new byte[4];
		b[3] = (byte) (0xff & i);
		b[2] = (byte) ((0xff00 & i) >> 8);
		b[1] = (byte) ((0xff0000 & i) >> 16);
		b[0] = (byte) ((0xff000000 & i) >> 24);
		for (byte c : b) {
			System.out.print("0x" + Integer.toHexString(c & 0xFF) + ",");
		}
		System.out.println();
	}
	public static void printBigEndian2(int i) {
		ByteArrayOutputStream bos = new ByteArrayOutputStream();
		DataOutputStream dos = new DataOutputStream(bos);
		try {
			dos.writeInt(i);
			dos.flush();
			bos.flush();
			byte[] data = bos.toByteArray();
			dos.close();
			bos.close();
			for (byte c : data) {
				System.out.print("0x" + Integer.toHexString(c & 0xFF) + ",");
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	public static int toLittleEndian(int i) {
		byte[] b = new byte[4];
		b[0] = (byte) (0xff & i);
		b[1] = (byte) ((0xff00 & i) >> 8);
		b[2] = (byte) ((0xff0000 & i) >> 16);
		b[3] = (byte) ((0xff000000 & i) >> 24);
		return b[3] & 0xFF | (b[2] & 0xFF) << 8 | (b[1] & 0xFF) << 16
				| (b[0] & 0xFF) << 24;
	}

大端序把最后返回的顺序改下即可。
