验证电子邮件地址是否包含“@”和“。” [英] validate that an email address contains "@" and "."

问题描述

我需要验证插入的电子邮件地址是否包含@和。没有正则表达式。
有人可以给我java代码和结构图的例子吗？

i need to validate that an inserted email address contains "@" and "." without a regular expression. Can somebody to give me "java code" and "structure chart" examples please?

推荐答案

我嫌疑人你有这样的事情：

if (!address.contains("@") || !address.contains("."))
{
    // Handle bad address
}

编辑：当然，这远远不是一个完整的验证。这几乎不是验证的开始，但希望这将使您能够处理您想要处理的特定情况。

This is far from a complete validation, of course. It's barely even the start of validation - but hopefully this will get you going with the particular case you wanted to handle.
