I'm attempting to read a certain file in Java and make it into a multidimensional array. Whenever I read a line of code from the script, The console says:

Caused by: java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
I know that this error is caused when the coding can't reach the specific index, but I have no idea how to fix it at the moment.
Here is an example of my coding.
int x = 1;
while (scanner.hasNextLine()) {
  String line = scanner.nextLine();
  //Explode string line
  String[] Guild = line.split("\\|");
  //Add that value to the guilds array
  for (int i = 0; i < Guild.length; i++) {
    ((ArrayList)guildsArray.get(x)).add(Guild[i]);
    if(sender.getName().equals(Guild[1])) {
      //The person is the owner of Guild[0]
      ownerOfGuild = Guild[0];
**Text Document **
Test|baseman101|baseman101|0|
Test2|Player2|Player2|0|
Other solutions, such as the one found here: Write to text file without overwriting in Java
Thanks in advance.
                Well, Exception says what's happening at Exception level. Array is size 1 and you access position 1. Your logic is not ok!

                They do increase dinamically, however they're 0 based and accessing to a bigger index than the actual one will result in an Exception

You are increasing  x  so if x >= guildsArray.size() then you will get java.lang.IndexOutOfBoundsException
solution 
if( x >= guildsArray.size())
      guildsArray.add(new ArrayList());
for (int i = 0; i < Guild.length; i++) {
    ((ArrayList)guildsArray.get(x)).add(Guild[i]);
    if(sender.getName().equals(Guild[1])) {
      //The person is the owner of Guild[0]
      ownerOfGuild = Guild[0];
