可以使用 Java 中的 ByteBuffer 类来进行字节序列的转换操作。具体步骤如下：

1. 把要转换的字节序列存储到一个 byte 数组中

byte[] bytes = {0x1B, 0x02, 0x04, (byte)0x80, (byte)0xFF, (byte)0x82, (byte)0xA7, 0x00, (byte)0xEF, (byte)0xFE, (byte)0xFE, 0x7F, 0x43, (byte)0xFF, 0x38, (byte)0xFF, 0x5B, 0x01, (byte)0xAA, 0x02, (byte)0xFF, 0x7F, 0x0A, 0x01, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, 0x34, 0x00, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, (byte)0x89, 0x01, 0x32, 0x00, 0x5C, 0x00, 0x5F, 0x00, 0x58, 0x00, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, 0x1E, 0x00, 0x64, 0x00, (byte)0x9E, 0x01, (byte)0x86, (byte)0xBA, 0x03, 0x00, (byte)0xDE, 0x1E, 0x00, 0x00, (byte)0xF0, 0x4D, 0x0F, 0x00, (byte)0xFE, 0x7F, (byte)0xFE, 0x7F, (byte)0xEF, (byte)0xFE, 0x43, (byte)0xFF, (byte)0xF5, 0x0C, 0x00, 0x00, (byte)0xD3, 0x01, 0x1C, 0x01, (byte)0xFE, 0x7F, (byte)0xFF, 0x7F, (byte)0xB9, (byte)0xD6, 0x1B, 0x04, (byte)0xFF, (byte)0xFF};

2. 创建 ByteBuffer 对象，设置字节序为 Little-endian

ByteBuffer buffer = ByteBuffer.wrap(bytes);
buffer.order(ByteOrder.LITTLE_ENDIAN);

3. 使用 getShort() 方法获取下一个 short 类型的数据，并除以 10 得到转换后的结果

short value = buffer.getShort();
float result = value / 10.0f;

4. 重复第3步，直到获取到所有要转换的数据，最后得到的结果即为 -18.9

while (buffer.hasRemaining()) {
    short value = buffer.getShort();
    float result = value / 10.0f;
    System.out.println(result);
}
