Error when giving player an item.

Hey guys, I'm working on a crates (Not voting) plugin. I get an error when the server tries to give me the item that is in the config list.
Here is my code:

Code:

    @EventHandler
    public void placeblock(BlockPlaceEvent event) {
        Player player = (Player) event.getPlayer();
        List<String> list = Main.main.getConfig().getStringList("Items");
        int index = new Random().nextInt(list.size());
        String cmd = list.get(index);
        Block block = event.getBlockPlaced();
        Location loc = block.getLocation();
        int x = block.getLocation().getBlockX();
        int y1 = block.getLocation().getBlockY();
        int y2 = block.getLocation().getBlockY() + 1;
        int y3 = block.getLocation().getBlockY() + 2;
        int y4 = block.getLocation().getBlockY() + 3;
        int y5 = block.getLocation().getBlockY() + 4;
        int z = block.getLocation().getBlockZ();
        String[] idAndName = cmd.split(":");
        String id = idAndName[0];
        String name = idAndName[1];
        if (block.getType() == Material.ENDER_CHEST) {
            Main.main.getServer().dispatchCommand(Bukkit.getConsoleSender(), "summon FireworksRocketEntity " + x + " " + y1 + " " + z + " {LifeTime:5,FireworksItem:{id:401,Count:1,tag:{Fireworks:{Explosions:[{Type:3,Flicker:1,Trail:1,Colors:[6487839],FadeColors:[16716032]},{Type:4,Flicker:1,Trail:1,Colors:[16711680],FadeColors:[16729438]},{Type:4,Flicker:1,Trail:1,Colors:[3374847],FadeColors:[16777024]},{Type:1,Flicker:1,Trail:1,Colors:[16769953],FadeColors:[16735389]}]}}}}");
            Main.main.getServer().dispatchCommand(Bukkit.getConsoleSender(), "summon FireworksRocketEntity " + x + " " + y2 + " " + z + " {LifeTime:5,FireworksItem:{id:401,Count:1,tag:{Fireworks:{Explosions:[{Type:3,Flicker:1,Trail:1,Colors:[6487839],FadeColors:[16716032]},{Type:4,Flicker:1,Trail:1,Colors:[16711680],FadeColors:[16729438]},{Type:4,Flicker:1,Trail:1,Colors:[3374847],FadeColors:[16777024]},{Type:1,Flicker:1,Trail:1,Colors:[16769953],FadeColors:[16735389]}]}}}}");
            Main.main.getServer().dispatchCommand(Bukkit.getConsoleSender(), "summon FireworksRocketEntity " + x + " " + y3 + " " + z + " {LifeTime:5,FireworksItem:{id:401,Count:1,tag:{Fireworks:{Explosions:[{Type:3,Flicker:1,Trail:1,Colors:[6487839],FadeColors:[16716032]},{Type:4,Flicker:1,Trail:1,Colors:[16711680],FadeColors:[16729438]},{Type:4,Flicker:1,Trail:1,Colors:[3374847],FadeColors:[16777024]},{Type:1,Flicker:1,Trail:1,Colors:[16769953],FadeColors:[16735389]}]}}}}");
            Main.main.getServer().dispatchCommand(Bukkit.getConsoleSender(), "summon FireworksRocketEntity " + x + " " + y4 + " " + z + " {LifeTime:5,FireworksItem:{id:401,Count:1,tag:{Fireworks:{Explosions:[{Type:3,Flicker:1,Trail:1,Colors:[6487839],FadeColors:[16716032]},{Type:4,Flicker:1,Trail:1,Colors:[16711680],FadeColors:[16729438]},{Type:4,Flicker:1,Trail:1,Colors:[3374847],FadeColors:[16777024]},{Type:1,Flicker:1,Trail:1,Colors:[16769953],FadeColors:[16735389]}]}}}}");
            Main.main.getServer().dispatchCommand(Bukkit.getConsoleSender(), "summon FireworksRocketEntity " + x + " " + y5 + " " + z + " {LifeTime:5,FireworksItem:{id:401,Count:1,tag:{Fireworks:{Explosions:[{Type:3,Flicker:1,Trail:1,Colors:[6487839],FadeColors:[16716032]},{Type:4,Flicker:1,Trail:1,Colors:[16711680],FadeColors:[16729438]},{Type:4,Flicker:1,Trail:1,Colors:[3374847],FadeColors:[16777024]},{Type:1,Flicker:1,Trail:1,Colors:[16769953],FadeColors:[16735389]}]}}}}");

            block.getWorld().strikeLightning(loc);
            TitleAPI.sendTitle(player, 10, 15, 10, "§a§lYou got", "§e§l" + name);
            player.getInventory().addItem(new ItemStack(Material.getMaterial(id)));
            Bukkit.getScheduler().scheduleSyncDelayedTask( Main.main, new Runnable() {
                @Override
                public void run() {
                    event.getBlock().setType(Material.AIR);
                }
            }, 20L);
        }
    }

The error is at player.getInventory().addItem(new ItemStack(Material.getMaterial(id)));
My modified config is:

Code:

Items:
- 322:Apple
- 267:IronSword
- 276:DiamondSword
- 310:Cap
- 311:ChestProtector
- 312:Leggings
- 313:FarmerBoots

Error:

@DarkenCake your comment was totally useless.

@Edmond506 For me it looks like it has problems with parsing the id to Material, try to print out what it is exactly before changing it to material. And check if the material is null after doing so.

 

Can you give me an example? It works when I don't seperate the id and the name. But I need to seperate it to display the item name and give the player the exact item displayed.

 

Example for what? System.out.println, player.sendMessage() ?

 

Ok so
First you do Material myMaterial = Material.getMaterail(MaterialName)
then if myMaterial is null send player a error message
else do what you wanted to do with material.

If you need the ID then loop through them and compare the ID with the input. If its the same then just use that material. WHen the loop ends you send the error message if material is not found.

And no, noone will give you "example" code. Its called spoonfeeding, as known as getting someone else to do your work.
