Question

Hello im coding a plugin for the game minecraft using Bukkit. Basically when a player right clicks with a egg that egg has a specific durability. The durability does not change at all because the event is called every time someone does this and its individual. The code i currently have is not done but this is basically it:

if (e.getItem().getTypeId() == 383) {
        if (!worldguardPlugin.canBuild(e.getPlayer(), loc)) {
            e.setCancelled(true);
            e.getPlayer().sendMessage(
                    ChatColor.YELLOW
                            + "You cant use spawner eggs in this region!");
            return;
        }
        switch (e.getItem().getDurability()) {
        case 2:
            expOrb(e);
            break;
        case 9:
            painting(e);
            break;
        case 20:
            primedTnt(e);
            break;
        case 40:
            minecart(e);
            break;
        case 41:
            boat(e);
            break;
        case 50:
            creeper(e);
            break;
        case 51:
            skeleton(e);
            break;
        case 52:
            spider(e);
            break;
        case 53:
            giant(e);
            break;
        case 54:
            zombie(e);
            break;
        case 55:
            slime(e);
            break;
        case 56:
            ghast(e);
            break;
        case 57:
            pigman(e);
            break;
        case 58:
            enderman(e);
            break;
        case 59:
            cavespider(e);
            break;
        case 60:
            silverfish(e);
            break;
        case 61:
            blaze(e);
            break;
        case 62:
            cube(e);
            break;
        case 63:
            dragon(e);
            break;
        case 90:
            pig(e);
            break;
        case 91:
            sheep(e);
            break;
        case 92:
            cow(e);
            break;
        case 93:
            chicken(e);
            break;
        case 94:
            squid(e);
            break;
        case 95:
            wolf(e);
            break;
        case 96:
            moosh(e);
            break;
        case 97:
            snowGolem(e);
            break;
        case 98:
            ocelot(e);
            break;
        case 99:
            ironGolem(e);
            break;
        case 120:
            villager(e);
            break;
        case 200:
            crystal(e);
            break;
        default:
            break;
        }
    }
}

Since I’m using break, all of the methods i made won’t be called correct? That would cause lots of pointless code being executed and wasted performance, and the entire point of this design was for better work flow.

Answer 1

Your assumption is correct. Only the code that meets the specific switch case will be executed. After all, a switch statement is a substitute for a giant if-else if-else block.
