Java comparing 2D array to digit is giving exceptions -


i'm trying compare 2d array digit, throwing exception.

code

import org.newdawn.slick.color;  public class main {      public static int[][] map = {{0, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {1, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {2, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {3, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {4, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {5, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {6, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1},     {7, 2, 1, 3, 4, 1, 1, 3, 4, 1, 3, 5, 1}};      public static void main(string args[]) {         int = 0;         int ii = 0;          (int y = 0; y < 7; y++) {              (int x = 0; x < 11; x++) {                  if (map[x][y] == 0) {                     g.setcolor(color.blue);                     g.fillrect(i, ii, 100, 100);                 }                 if (map[x][y] == 1) {                     g.setcolor(color.orange);                     g.fillrect(i, ii, 100, 100);                 }                 if (map[x][y] == 2) {                     g.setcolor(color.white);                     g.fillrect(i, ii, 100, 100);                 }                 if (map[x][y] == 3) {                     g.setcolor(color.red);                     g.fillrect(i, ii, 100, 100);                 }                 if (map[x][y] == 4) {                     g.setcolor(color.green);                     g.fillrect(i, ii, 100, 100);                 }                 if (map[x][y] == 5) {                     g.setcolor(color.gray);                     g.fillrect(i, ii, 100, 100);                 }                 = x * 100;                 = y * 100;             }         }     } }

the exception throwing java.lang.arrayindexoutofboundsexception: 8 bare bones tile map system, if want test need slick2d , need put in render loop.

it because trying access row 8 , have maximum of position 7.

remember index of rows , columns starts in position 0 , ends in length-1.

also, have remember first position of array, in case, x, rows, , y columns.

array[rows][columns]

so have change order of variables in loops. this:

for(int x = 0; x < map.length; x++){      for(int y = 0; y < map[x].length; y++){

the rest of code can have above.

i expect helpful you!
