Solved ArrayIndexOutOfBoundsException: 0

so I'm getting this error from line 53 when I typed /crime and I have no idea what causes that error.

Code:java

if (command.getName().equalsIgnoreCase("crime")) {
if (sender instanceof Player) {
Player player = (Player) sender;
String sendername = sender.getName();
if ((player.hasPermission("crime.config")) || (player.isOp() == true)) {
try {
if (args[0].equalsIgnoreCase("joblist")) {
showJobs(sender, args);
} else {
doCommand(sender, args);
}
} catch (Exception ex) {
showAbout(sender);
} //LINE 53 STARTS BELOW HERE
} else if (args[0].equalsIgnoreCase("jobs")) {
showJobs(sender, args);
} else if (args[0].equalsIgnoreCase("join")) {
String[] jobslist = {"Pet", "Supplier", "Pilot", "Engineer", "Terrorist", "Thugs", "Hitman", "Robber", "Hax0r", "Cops", "Detective", "Watcher", "Gun Dealer", "Armory", "Brewer"};
if ((config.getBoolean(sendername + ".joinedjobs") == false) && (config.getInt(sendername + ".exp")) >= 1000) {
if (args.length >= 2) {
if (Arrays.asList(jobslist).contains(args[1])) {
config.set(sendername + ".jobs", args[1].toUpperCase());
config.set(sendername + ".joinedjobs", true);
config.set(sendername + ".exp", config.getInt(sendername + ".exp") - 100);
sender.sendMessage(yellow + "Crime" + red + "-== " + gray + "You have successfully changed your jobs into " + args[1]);
saveConfig();
} else {
sender.sendMessage(yellow + "Crime" + red + "-== " + gray + "The jobs you specified doesn't exist !");
}
} else {
sender.sendMessage(yellow + "Crime" + red + "-== " + gray + "Specify the jobname");
}
} else {
sender.sendMessage(yellow + "Crime" + red + "-== " + gray + "You don't have 100 EXP or you've already choose a Job.");
}
}
} else {
doCommand(sender, args);
}
} else {
showAbout(sender);
}

Incase you need the showJobs
showJobs :

Code:java

try {
if ((args[1].equalsIgnoreCase("1")) || args[1].equalsIgnoreCase(null)) {
//bunch of send messages
} else if (args[1].equalsIgnoreCase("2")) {
//same
} else if (args[1].equalsIgnoreCase("3")) {
//same
}
} catch (Exception ex) {
//The exact same messages from previous one.
}

 

You aren't checking to see if args is even above 0.

EDIT: And what's with the try/catch? That could be easily done with an if statement. Your try/catch caught the your first args error but not the second which is at line 53

 

thanks ! solved now .

I will change the try catch block after this one .
