My apologies, here's a Java function that implements the Gray code and returns the next sequence code after a given code in a given direction of rotation:

```
public static int getNextGrayCode(int code, int direction) {
    int MSB = code & (1 << Integer.SIZE - 1);
    code = code ^ (code >> 1);
    if (direction == 1) {
        code = code & ~(1 << Integer.SIZE - 2);
        code = code | MSB >> 1;
    } else {
        code = code | (1 << Integer.SIZE - 2);
        code = code & ~MSB >> 1;
    }
    return code;
}
```

The function takes two parameters: code and direction. code is the current gray code, and direction determines the direction of rotation (clockwise or counterclockwise). If direction is 1, the function returns the next gray code in a clockwise direction. If direction is 0, the function returns the next gray code in a counterclockwise direction.
