Re: index of array
What you mean is, you want to check if a string is in a array, then if it is, get the index, right?
If the array is a ArrayList you can't check with the string alone, ArrayList.get() needs the index. So make a for() loop and check if the value is the same as the string, if it is, take the index.
Here is some example code:
int newIndex; for(int i = 0; i<ArrayList.size(); i++) { if(ArrayList.get(i).equals(stringValue) { newIndex = i; } }
It would be possible to check with the string if it was not a ArrayList but a Hashtable.
