Create a version of what we covered in class on 1/21/17. Submit it on Moodle before Tuesday's lecture.
Implement a Threaded version of the Game of Life in Java
Requirements
- Only two threads working
- The two threads are running identical code
- The manager displays only the last generation. No need for the manager to synchronize itself with the workers every generation. This will make it simpler to code.
- Since the threads need to share the dish arrays (and maybe other arrays or variables), one good way to share the array of strings is to put it in a static class, as follows:
class data { static String[] dish= { " ", " # ", " # # ### ", " ## ", " ", " # ", " # # ", " ## ", " ", " " }; }
- The class data can be declared in the same file that contains the public manager class, as well as the thread class.
- Whenever a thread needs to access the dish array, it can just access data.dish, as illustrated below, with the inner loop of the life() function:
for ( int j=i-1; j<=i+1; j++ ) { // make sure we wrap around from left to right int realj = j; if ( j==-1 ) realj = data.dish[row].length()-1; if ( j==data.dish[row].length() ) realj = 0; if (r==row && j==i ) continue; // current cell is not its // neighbor if (data.dish[realr].charAt(realj) == '#' ) neighbors++; }
