Java代码如何验证电子邮箱输入是否正确呢?

验证电子邮箱的实现思路

只需定义验证邮箱的正则表达式
   即可实现验证电子邮箱的效果

public static final String EMAIL_REGEX_DEFAULT = "^([a-z0-9A-Z]+[-|_|\\.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?\\.)+[a-zA-Z]{2,}$";

public static boolean isEmail(String email) {
    return email.matches(EMAIL_REGEX_DEFAULT);
}
public static boolean isEmail1(String email) {
    Pattern p = Pattern.compile(EMAIL_REGEX_DEFAULT);
    Matcher m = p.matcher(email);
    return m.matches();
}
