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];
}
}
x++;
}
**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.
problem 1 -> int x = 1;
solution: The x should be start with 0
problem 2->
((ArrayList)guildsArray.get(x)).add(Guild[i]);
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];
}
}
