multidimensional array - Referring to variable in Java? -


i have 3d array called em:

double[][][] em = new double[4][4][4];

i have helper method converts intto char:

public static char inttochar(int i) {     switch (i) {     case 0:         return 'a';     case 1:         return 'b';     case 2:         return 'c';     default:         return 'd';     } }

i have 4 integer variables:

int = 108; int b = 299; int c = 302; int d = 411;

now, here tricky part. want go through each index of 3d array em , multiply index values. [0][0][0] = 1*1*1 = 1; [0][0][1] = 1*1*2 = 2; ...; [3][3][3] = 4*4*4 = 64.

for (int i=0; i<4; i++){     (int j=0; j<4; j++){         (int k=0; k<4; k++){             char = inttochar(i);             char j = inttochar(j);             char k = inttochar(k);             // not sure here         }     } }

how can that?

you need able refer a...d index, need index them in array:

int[] d = {a, b, c, d};

which goes before loop. loop easy:

em[i][j][k] = d[i]*d[j]*d[k];

this set each of values @ (i,j,k) corresponding a...d multiplicands.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
