index out of bound error

public class settasks extends BLTHAdapter {
     String subroleArr[];
     static int i=0;
     static int j;
    public void handleSetSubject(BLTHContext ctx) throws Exception 
    {
    try{
                        ..... some code   
    for(j=0;j<v.size();j++,i++)
    {    
 
        subroleArr[i]=some string
       getsubroleArr(subroleArr[i],ctx);               
 
    }
 
    adminrole.setRoleDescription(subroleArr[0]);
}
catch(Exception e)
    {
    throw e;
 
    }
}
public void getsubroleArr(String v,BLTHContext ctx1)throws Exception
{
..some code    
while(some condition )         
 {
 
i++;
subroleArr[i]=some string
getsubroleArr(subroleArr[i],ctx1); //function called recursively
 
}
}        
 
        }
 

The above code is wrtitten using API's .I have written a recursive function getsubrolArr() , this recursive fucntion is storing values in a array. For counter of the array i have used a static variable i.
But when I am trying to increment i in the function getsubrole. I am getting "java.lang.ArrayIndexOutOfBoundsException: 2"
Is there any thing wrong in the incrementing i in the above code.
Any pointers will be very helpful

I have no idea what your code is supposed do, what this immediately caught my eye:

static int i=0;
static int j;

Static loop variables? In all my years of programming I've never seen that attempted. Could this be your error?

What did you initialize subroleArr[]'s length to be?

What did you initialize subroleArr[]'s length to be?

I don't think that matters much because that code shows that the index variable 'i'
is only incremented and never reset to a sensible value, so once 'i' will be larger
than the maximum array index. (ignoring an array having Integer.MAX_VALUE
elements)

kind regards,
