trim @domain.xxx from email leaving just username
提问by Code Junkie
I'm trying to trim the @domain.xxx from email address leaving just the username. I'm not sure how to dynamically select the @ position and everything to the right of it. Could someone please provide an example of how to do this? The trim code below is where I'm lost.
我正在尝试从电子邮件地址中删除 @domain.xxx，只留下用户名。我不确定如何动态选择 @ 位置及其右侧的所有内容。有人可以提供一个如何做到这一点的例子吗？下面的修剪代码是我迷路的地方。
email = "[email protected]"
email....(trim code);
email.replace(email, "");

To find:
int index = string.indexOf('@');
查找：
int index = string.indexOf('@');
To replace:
email = email.substring(0, index);
取代：
email = email.substring(0, index);
To summarize:
总结一下：
email = "[email protected]";
int index = email.indexOf('@');
email = email.substring(0,index);

Another approach is to split an email on a nickname and on a domain. Look at javadoc
另一种方法是根据昵称和域拆分电子邮件。看javadoc
There is a code example:
有一个代码示例：
String email = "[email protected]";
String[] parts = email.split('@');
// now parts[0] contains "example"
// and parts[1] contains "domain.com"
