java 生成复杂密钥 java密码自动生成器

还有一个修改生成文件路径的功能,以后再写

附上代码

//字典计算
/*猜测:可能赋值成功了,但是都被int识别为了一个0,可能需要转换成字符串累加
* 这可能会导致上面的操作被视为同一种
* int a = 0; 和  int a = 00000000;        可能在int看来都是0,这导致了最小数不能以000000开始

目前未处理的问题

最小位数无论设置成几位都没效果,它们都会从0开始,这里的0可能在输出之前被int视为了一个0,因为他有可能是000000000-999999999,在int类型看来就是一个0

我后来是把他们分开处理了就是在计算之前先加上当前应该得到的位数0补上,但是位数一旦不是个位时0就会多出来,但不会影响正常使用
