[1.7.10] Block droping 1-3 items from ArrayList

[robmart]

How do i make a block drop 1-3 items (randomly)

I have this code for dropping items

 

@Override

    public ArrayList<ItemStack> getDrops(World world, int x, int y, int z, int metadata, int fortune) {

        ArrayList<ItemStack> items = new ArrayList<ItemStack>();

        items.add(new ItemStack(InitItem.StrawberrySeed));

        items.add(new ItemStack(InitItem.Strawberry));

        return items;

    }
