I can give you a starting tutorial with item NBT data.

All ItemStacks in a world can contain additional data called NBT data. You can write NBT data to an ItemStack like so:

public void storeIntegerInItemStackNBT(ItemStack itemStack, String tagKey, int number) {
    // If an ItemStack doesn't have NBT data associated with it, then the stackTagCompound (returns an NBTTagCompound object) field will be null.
    if (itemStack.stackTagCompound == null) {
        // NBTTagCompound is the object that stores an ItemStack's NBT data
        itemStack.setTagCompound(new NBTTagCompound());
    }
    // NBTTagCompound has many methods to store many data types, including bytes, byte arrays, shorts, integers, Strings, etc.
    // When storing values using NBTTagCompound, you will also need a key (String) to associate with the value. This is for calling the value later when you want to extract information from an NBTTagCompound object.
    itemStack.stackTagCompound.setInteger("Key", number);
}

You can read NBT data from an ItemStack like so:

public int readIntegerFromItemStackNBT(ItemStack itemStack, String tagKey) {
    if (itemStack.stackTagCompound == null) {
        itemStack.setTagTagCompound(new NBTTagCompound());
    }
    return itemStack.stackTagCompound.getInteger(tagKey);
}

That's the basics of ItemStack NBT data. You can also check out this: http://www.minecraftforum.net/topic/982336- tutorial for more information.

if (user.hasKnowledgeOfJava) {

if (user.question.hasCode) {

return interpetHelpfulResponse(user.getQuestion());

} else {

return "Could you post your code please?";

}

} else {

return "Learn some freaking Java!";
