Question

我不太了解BufferOverflowException（）的含义/目的; 在我的课程中，我们使用它来编码队列，同时在队列中添加元素，我们使用BufferOverflowException。

根据docs.oracle，它表示＆＃34;当相对put操作达到目标缓冲区的限制时抛出未经检查的异常。＆＃34;我仍然不明白它的含义。

Answer 1

缓冲区溢出意味着为应用程序提供了太多数据。

示例：将图书文本复制到手机上的“新联系人姓名”。

通常，如果处理不当，则会导致 chrash ...
更重要的是，它可能是一个安全漏洞！

额外数据可以存储在程序指定内存之外，额外数据可以是可执行代码。

因此，始终验证用户输入是一种好习惯！：）
