Java中的循环有两种主要形式：while{} 和 do{}while，它们的主要区别如下：while{} 循环：工作原理：先判断条件表达式是否为真，如果条件为真，则执行循环体内的代码块；如果条件为假，则跳过循环体，继续执行循环之后的代码。特点：条件满足时才执行循环体，因此可能一次都不执行。do{}while 循环：工作...

你的两个for循环都当i值和j值达到输入值的长度时，就宏大跳出了循环,而此时下标已等于了输入值的长度,所以你在charc=ch[i];应该就已经亩绝悉发生了数组下标越界错误.你去掉两个for循环后面的;号，可能解决这个迅乎问题【xze.tzd07.vip/news/076213.html】【bxo.cqdht.icu/news/518794.html】【...
