PrepareItemCraftEvent重复项

Question

在PrepareItemCraftEvent中存在错误，即它是关于重复项目的。创建对象时，项目数暂时跳转到8或16或64。

我的代码：

if (e.getInventory().getResult() !=null) {
    if (e.getInventory().getResult().getType().equals(its.getType())) {
        if (e.getInventory().getItem(1) != null) {
            if (e.getInventory().getItem(1).getAmount() >= a
                && e.getInventory().getItem(2).getAmount() >= b
                && e.getInventory().getItem(3).getAmount() >= c
                && e.getInventory().getItem(4).getAmount() >= d
                && e.getInventory().getItem(5).getAmount() >= ee
                && e.getInventory().getItem(6).getAmount() >= f
                && e.getInventory().getItem(7).getAmount() >= g
                && e.getInventory().getItem(8).getAmount() >= h
                && e.getInventory().getItem(9).getAmount() >= i) {
                    return;
            } else {
                    e.getInventory().setResult(new ItemStack(Material.AIR, 1));
            }
        }
    }
}
