Execute Brain****/Java: Difference between revisions

Under the hood, the program memory is an ArrayList of Integers which expands only"infinitely" (limited by your system's memory) to the right (still [http://en.wikipedia.org/wiki/Turing_completeness Turing complete]). So, if the pointer moves past zero to the left, the program will exit and a "Pointer out of range" error message will be displayed. Due to the BufferedReader input class, return characters ([http://www.asciitable.com ASCII] 10 and 13) are ignored on input (the , command), but are not ignored on output (the . command). More detailed information can be found in the comments scattered about the code.
