Indexes start at 0 and end at Length -1. if you remove the +1 in your for loop this will fix the problem. Edit: yes a enhanced for loop would work.
I fixed the loop with this working fine and sending the list, but there are still error Code (Java): for(int i = 0; i < (items + 1); i++) { Code (Java): [00:42:18 ERROR]: null org.bukkit.command.CommandException: Unhandled exception executing command 'cr' in plugin CustomRecipe v1.0 at org.bukkit.command.PluginCommand.execute(PluginCommand.java:46) ~[spi got-latest.jar:git-Spigot-e6f93f4-ed60c01] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:14 1) ~[spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at org.bukkit.craftbukkit.v1_9_R1.CraftServer.dispatchCommand(CraftServe r.java:645) ~[spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.PlayerConnection.handleCommand(PlayerCon nection.java:1350) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.PlayerConnection.a(PlayerConnection.java :1185) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.PacketPlayInChat.a(PacketPlayInChat.java :45) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.PacketPlayInChat.a(PacketPlayInChat.java :1) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.PlayerConnectionUtils$1.run(SourceFile:1 3) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [ ?:1.8.0_91] at java.util.concurrent.FutureTask.run(Unknown Source) [?:1.8.0_91] at net.minecraft.server.v1_9_R1.SystemUtils.a(SourceFile:45) [spigot-lat est.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.MinecraftServer.D(MinecraftServer.java:7 21) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.DedicatedServer.D(DedicatedServer.java:4 00) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.MinecraftServer.C(MinecraftServer.java:6 60) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at net.minecraft.server.v1_9_R1.MinecraftServer.run(MinecraftServer.java :559) [spigot-latest.jar:git-Spigot-e6f93f4-ed60c01] at java.lang.Thread.run(Unknown Source) [?:1.8.0_91] Caused by: java.lang.IndexOutOfBoundsException: Index: 4, Size: 4 at java.util.ArrayList.rangeCheck(Unknown Source) ~[?:1.8.0_91] at java.util.ArrayList.get(Unknown Source) ~[?:1.8.0_91] at org.madmaxcookie.CommandCr.onCommand(CommandCr.java:84) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[spi got-latest.jar:git-Spigot-e6f93f4-ed60c01] ... 15 more >

The problem is you are setting your items variable to a number higher then the number of objects in that arraylist. Use ArrayList#.size(); Code (Text): for(int i = 0; i < ArrayList#size(); i++) {
what ? can you check my new code if I removed + 1 Code (Java): if(args[0].equalsIgnoreCase("list")) { if(!Permitted("customrecipe.list", p)) { p.sendMessage(prefix("Error") + "Not permitted to do that"); return true; } Set<String> s = new HashSet<String>(); if(ca.getConfig().getKeys(false) == null) { p.sendMessage(prefix("Error") + "No recipes defined"); }else { s.addAll(ca.getConfig().getKeys(false)); } List<String> list = new ArrayList<String>(s); Collections.sort(list); int warps = list.size(); p.sendMessage(colorize("&bCustomRecipe &6&l>&e&l> &8: &7Recipes")); p.sendMessage(colorize("&6&l=====&e&l===== &e&l=====&6&l=====")); if(warps >= items) { for(int i = 0; i < (items + 1); i++) { for(String b : Arrays.asList(list.get(i))) { try { p.sendMessage(colorize("&6&l>&e&l> &8: &7" + b)); }catch(IndexOutOfBoundsException e) { e.printStackTrace(); } } } }else { for(int i = 0; i < warps; i++) { for(String b : Arrays.asList(list.get(i))) { p.sendMessage(colorize("&6&l>&e&l> &8: &7" + b)); } } } p.sendMessage(colorize("&6&l=====&e&l===== &e&l=====&6&l=====")); if(warps >= items) { p.sendMessage(prefix("Success") + "Page &61 / &6" + warps / items + (list.size() % items)); }else { p.sendMessage(colorize("&6&l>&e&l> &8: &7Page &61 &7/ &61 &e&l<&6&l<")); } return true; }
Not sure what you did. I still see the +1, however I stopped reading once I noticed "b", "s" and "ca". Bad variable names, loss of interest. LO SIENTO.
I hope you won't judge more people but I just did is fixed this error called IndexOutOfBoundsException nothing to do with + 1
get(i) the i is greater than the size of the array list which throws IOOBE I did at the loop was Code (Java): for(int i =0; i < (items +1); i++){
Yes, so how did you avoid it? Removing the +1 would result in the .get() not being called for the size+1.
