You read the line BUT inside the loop you don't do anything with it. Instead you call this:
Integer.parseInt(account[count][1]); .
The account array is not 2-D and the Integer.parseInt does not return an array.


Now inside the line you have something like this:
12345 1234 200000 Jerry Lopez

So If you use the split method:

String [] array = line.split(" ");

String [] array = line.split(" ");

The elements of the array would be:
0: 12345
1: 1234
2: 200000
3: Jerry
4: Lopez

Also for reading from a file try this shorter version:

BufferedReader lnr = new BufferedReader (new FileReader("accountList.txt"));

BufferedReader lnr = new BufferedReader (new FileReader("accountList.txt"));
