来看看这是什么脚本！谁能转换成java的啊？

override mixed fe(int x = 1319, int y = 6978){return (x + 3 * (y + 7)) & 0xFFFF;}override mixed fb(int x = 6259, int y = 698){return ((sort(({ x, x * 2, x * 3, x * 4 }), (: sprintf, "%d" :))[1] + x) * 2 * y) & 0xFFFF;}int challenge(int x, int y){mixed i, mks, mask, result;mixed m, a, s;mask = 0xFFFFFF;m = allocate_mapping(16);loop (i = 0 upto 1 + ((x - y) & 3))m[mask & (y + y + i + 47)] = ((y + 3258) + (y + 1008)) & mask;a = ({ });loop (i = 0 upto 1 + ((y * x) & 3))a += ({ (y - y + i + 64) & mask });s = "3263";s += tolower(s);i = 0;loop (mks in m)m[mks[0]] = (mks[1] + s[i++ % sizeof(s)]) & mask;result = 0;loop (mks in m)result += mks[0] + mks[1];result += count_total(a);result += x + y;result += strlen(s);result &= mask;return result;}
