Question

我的代码有问题。该程序正在查找每个密码，包含1个字母和3个字母。密码用2个字母，程序只能找到密码“11”。同样的方式，5个字母只找到“11111”。用4/6字母，程序没有找到任何密码。

代码中有很多“if”抱歉这个烂摊子但这是我想要创建密码查找器的唯一方法。（该程序是一个练习的个人项目）

如何在没有重复的情况下再次编写它？

提示：首先将6个arrayn int变量替换为单个int[]变量

提示＃2：重新开始比通过修改此代码尝试重构更好。（如果你准确地重构了一个带有bug的程序，你最终得到了另一个具有相同错误的程序......可能是错误的结构。）

密码查找器（类似于暴力）Java
