Java bytes are signed, and range from -128 to +127; thus they are always less than 0xff (256). Therfore "a" is always 0 and the innermost loop runs until the program runs out of memory. To patch this up: use "int" counters, and cast to bytes. Furthermore, note that you want your loops to count from 0 to 0xff, so the ... |

Essentially the router communicates with other Internet sites on behalf ... |
