How do I make a String array increment?

Question

I am getting jumbled up with this and I might know the answer. How do I make my String[] array increment every time this function is called? Here is the function code:

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){ //The /ticket command if(cmd.getName().equalsIgnoreCase("ticket")){ //Gets amount of arguments int size_of_args = args.length; String ticket = null; String[] ticket_array; //Puts ticket into one string to be stored. for (int i=0; i<=size_of_args; i++){ ticket = ticket + args[i]; } return true; } else {return false;} }

I think I have to do a for loop, but I am very tired and this has been stumping me for quite a while. The function is not complete, so do not mention that I haven't used String commandLabel or CommandSender sender (sorry if that sounds rude). Thanks in advance!

P.S. I do not want to set a value for String[] ticket_array because the amount of tickets made should be as many as there are sent in.

@jacobm Sorry about my clarity. I mean increment the value at which ticket is stored. So the first time the function/method is called ticket_array[0] = ticket; and second time ticket_array[1] = ticket;and etc. — VinylScratch

Consider using a List instance as class member, this way, you don't need to worry regarding the size, for example:

List<String> commandList = new ArrayList<String>(50); public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){ //The ticket command if(cmd.getName().equalsIgnoreCase("ticket")){ String ticket = ""; // ommiting commandList.add(ticket); return true; } else { return false; } }

I am new to this concept, what does this do and how do I access it in the future(like you access a string with ticket_array[10];)?

I cannot read that very well. I am rather new to Java. I am illiterate :D

I'm not sure if I'm understanding your question correctly but it sounds to me like you want to access a higher index of the array every time the function is called. If that's the case then you may want to consider using a static counter variable. this would have to be defined outside the scope of the function but it could be incremented during the function call

static int arrayCounter = 0; public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){ //The ticket command arrayCounter++; . . . }

then use

ticket_array[arrayCounter];

to access the desired index
