Regardless of any speedup, it's safer not to repeat the value. a[i][j] = a[i][j] + foo; looks a lot like a[i][j] = a[i][i] + foo; or a[i][j] = a[j][i] + foo; at first glance, whereas a[i][j] += foo; is unambiguous, and much clearer. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
