LinkedList within a for doesn't work

Question

If I run the lines all be good.

but if I run it there is a problem: java.lang.ArrayIndexOutOfBoundsException: 2 I don't understand how can there be a error if the code is doing what I wrote.

i=0 | y=0
i=0 | y=1
i=0 | y=2
Error EN HILO: java.lang.ArrayIndexOutOfBoundsException: 2

Before these lines, I work with matrix in those lines, but I don't think that this affect the program.

Answer 1

You are initializing INFOO like this

INFOO=new Object[FILAS][CANDIDATE_DE_COLUMNES]

As here CANDIDATE_DE_COLUMNES is <2 which is trowing exception for y=2

Answer 2

It could be because FILAS is equal to 3.

It also helps to align and format code correctly.

The following loop should replicate your single lines.

for(int i=0; i<2;i++)
{
   for(int j=0; j<2;j++)
   {
       System.out.println(i + " <-> " + j);
   }
}
