Hey, I want to get player's balance with this code: Code (Java): //Main class public static double getMoney(Player p) { double m = ekonomi.getBalance(p); return m; } //Command class if(args.length == 0) { if(sender instanceof Player) { Player p = (Player) sender; if(ekonomi.hasAccount(p)) { sender.sendMessage(prefix + "§7Money: §6" + Main.getMoney(p)); return true; } else { ekonomi.createPlayerAccount(p); return true; } } else { sender.sendMessage(prefix + "§4Only players can use this command."); return true; } } But I get this error: Code (Text): org.bukkit.command.CommandException: Unhandled exception executing command 'para' in plugin FFA v1.0 at org.bukkit.command.PluginCommand.execute(PluginCommand.java:46) ~[FFA.jar:git-Spigot-db6de12-18fbb24] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:141) ~[FFA.jar:git-Spigot-db6de12-18fbb24] at org.bukkit.craftbukkit.v1_8_R3.CraftServer.dispatchCommand(CraftServer.java:641) ~[FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.PlayerConnection.handleCommand(PlayerConnection.java:1162) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.PlayerConnection.a(PlayerConnection.java:997) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.PacketPlayInChat.a(PacketPlayInChat.java:45) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.PacketPlayInChat.a(PacketPlayInChat.java:1) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.PlayerConnectionUtils$1.run(SourceFile:13) [FFA.jar:git-Spigot-db6de12-18fbb24] at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [?:?] at java.base/java.util.concurrent.FutureTask.run(Unknown Source) [?:?] at net.minecraft.server.v1_8_R3.SystemUtils.a(SourceFile:44) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.MinecraftServer.B(MinecraftServer.java:715) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.DedicatedServer.B(DedicatedServer.java:374) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.MinecraftServer.A(MinecraftServer.java:654) [FFA.jar:git-Spigot-db6de12-18fbb24] at net.minecraft.server.v1_8_R3.MinecraftServer.run(MinecraftServer.java:557) [FFA.jar:git-Spigot-db6de12-18fbb24] at java.base/java.lang.Thread.run(Unknown Source) [?:?] Caused by: java.lang.ArrayIndexOutOfBoundsException: 0 at commands.Commands.onCommand(Commands.java:49) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[FFA.jar:git-Spigot-db6de12-18fbb24] ... 15 more Help pls.
Umm there is a } in line 44. Here is my command class: Code (Java): package commands; import java.util.Comparator; import org.bukkit.Bukkit; import org.bukkit.Sound; import org.bukkit.command.Command; import org.bukkit.command.CommandExecutor; import org.bukkit.command.CommandSender; import org.bukkit.configuration.ConfigurationSection; import org.bukkit.entity.Player; import org.bukkit.plugin.Plugin; import mainpackage.Main; import net.milkbowl.vault.economy.Economy; public class Commands implements CommandExecutor { private Plugin pl = Main.getPlugin(Main.class); public String prefix = "§8| §6§lGT §8| "; Economy ekonomi = Main.ekonomi; @Override public boolean onCommand(CommandSender sender, Command command, String komut, String[] args) { if(komut.equalsIgnoreCase("spawnbelirle")) { if(sender instanceof Player) { Player p = (Player) sender; if(p.isOp()) { pl.getConfig().set("Spawn.X", p.getLocation().getX()); pl.getConfig().set("Spawn.Y", p.getLocation().getY()); pl.getConfig().set("Spawn.Z", p.getLocation().getZ()); pl.getConfig().set("Spawn.Yaw", p.getLocation().getYaw()); pl.getConfig().set("Spawn.Pitch", p.getLocation().getPitch()); p.sendMessage(prefix + "§7Spawn belirlendi!"); p.getWorld().strikeLightningEffect(p.getLocation()); pl.saveConfig(); return true; } else { p.sendMessage(prefix + "§4Hayırdır? Beğenmedin mi spawn'ı?"); p.getWorld().playSound(p.getLocation(), Sound.VILLAGER_NO, 50, 1); return true; } } else { sender.sendMessage(prefix + "§4Bu komudu sadece oyuncular kullanabilir."); return true; } } // Line 44 if(komut.equalsIgnoreCase("para") || komut.equalsIgnoreCase("money") || komut.equalsIgnoreCase("bal") || komut.equalsIgnoreCase("balance")) { if(args[0].equalsIgnoreCase("ekle")) { if(args.length == 3) { Player p = Bukkit.getPlayer(args[1]); int eklenen = Integer.parseInt(args[2]); ekonomi.depositPlayer(p, eklenen); p.sendMessage(prefix + "§6" + sender.getName() + "§7 tarafından hesabına §e" + eklenen + "TL §7eklendi." + ekonomi.getBalance(p)); return true; } } if(args[0].length() == 0) { if(sender instanceof Player) { Player p = (Player) sender; sender.sendMessage(prefix + "§7Paran: §6" + Main.getMoney(p)); return true; } else { sender.sendMessage(prefix + "§4Bunu sadece oyuncular kullanabilir."); return true; } } } return false; } }
This is your first problem. You are checking what the first argument is without first checking there is a first argument, just replace that line with this one Code (Text): if(args.length > 0 && args[0].equalsIgnoreCase("ekle")) { This is your second problem. doing args[0] will give you a string, if that strings length is 0 it does not exist what I think you want to do it check if there are no arguments? if so then you should do args.length not args[0].length
You are accessing args[0] before checking its length. Side note, learn to read stacktraces, and always match the exact code with the stacktraces it's producing. Changing the code makes it harder to debug a stacktrace.
