java怎么判断一个邮箱名是否正确

[a-zA-Z0-9][a-zA-Z0-9._-]{2,16}[a-zA-Z0-9]@[a-zA-Z0-9]+.[a-zA-Z0-9]+
验证代码如下：
public static boolean isVaildEmail(String email){
     String emailPattern="[a-zA-Z0-9][a-zA-Z0-9._-]{2,16}[a-zA-Z0-9]@[a-zA-Z0-9]+.[a-zA-Z0-9]+";
     boolean result=Pattern.matches(emailPattern, email);
     return result;
}
