java - Getting IndexOutofBoundsException -


why here getting indexoutofboundsexception 16 , eclipse pointing following code in line:

 if((temp[0][0] == '.' && temp[0][height - 1] == '.') ||

if pass following string:

string layout =       "..aa\n"+       "..aa\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "aaaa\n"+       "aaaa\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "...a\n"+       "";

into method, im getting error. smb please me this? im pretty sure im doing smth wrong in conditionals after loops.note:layout strings shapes must have @ least 1 filled block in each of 0th row, 0th column, last row, , last column. thanks! 

 public static shape makeshape(string layout,char displaychar)   {       shape result;        int height = 0;       int width = 0;        scanner data = new scanner(layout);        while(data.hasnextline())       {           string line = data.nextline();           width = line.length();           height++;       }       char[][] temp = new char[height][width];       scanner data2 = new scanner(layout);       for(int = 0; < height; i++)       {            string line = data2.nextline();           for(int j = 0; j < width; j++)           {               if(line.charat(j) != '.')                   temp[i][j] = displaychar;                if(line.charat(j) == '.')                   temp[i][j] = line.charat(j);            }       }       data2.close();       if((temp[0][0] == '.' && temp[0][height - 1] == '.') ||         (temp[height - 1][0] == '.' && temp[height - 1][width - 1] == '.'))           throw new fititexception("empty borders!");        result = new createshape(height, width, displaychar, temp);         return result; }

you have temp[height - 1][width - 1] first index height , second lookup width. if these confused , use height width, , height larger width, going blow up.

perhaps intended temp[0][width -1]
