I have problem with ArrayIndexOutOfBoundsException and I don't know how to solve it!!!

C#

converted[0][0]=converted[0][0]+dfa[0][0];
for(int i=0;i<100 && i<converted[i].length ;i++){
LandaTrance();
for(int r=0;r<27 && Alpha[r]!=null && converted[i][0]!=null && r<Alpha.length;r++){
temp=search(converted[i][0],Alpha[r]);
if(temp.compareTo(not)!=0){
    converted[i][1].concat(converted[i][1]+Alpha[r]);
    converted[i][2].concat(converted[i][2]+","+temp);

Solution 1

In the outer loop you used converted[i] but, you didn't check that
i < converted.Length

It's a two dimensional array!how can I do that?

Just write converted.length instead of converted[i].length. You can see an example for the length property with 2 dimensional arrays, at this link: http://www.leepoint.net/notes-java/data/arrays/arrays-2D.html

I did what you said but still has the same error message...:(

Try to change the order of the conditions in the inner loop. Put the Alpha[r]!=null condition, after the r<Alpha.length condition.

thanks a lot for your help ! finally it worked :)

It is not a two-dimensional array! It's a "jagged array": a 1-dimensional array of 1-dimensional arrays.

My 5 for a catch.
