使用代码标签发布您目前使用的代码。

还有一件事你知道正则表达式。

看看这个并尝试它使用正则表达式。

记住它，Reg Exp。在J2SE-1.5中支持:-)


亲切的问候，

亲切的问候，

Dmjpro。

class StringDemo {

public static boolean isEmailAddress（String address）{

int dot，at;

dot = address.indexOf（"。"）;

at = address.indexOf（" @"）;

if （at == - 1 || dot == - 1 || address.length（）< dot ||（dot< at）&&）返回false;

else返回true;

}

public static void main（String [] arg）{

系统。 out.println（isEmailAddress（" lenguye .. @"））;

}


}

但是如果@ i之前的字符串conatin点不能处理

帮助我！这个问题我认为你并不困难

Post your Code what you tried so far with Code Tags.
One more thing do you know regular expression.
Have a look at this and try it using Regular Expression.
Mind it, Reg Exp. supported in J2SE-1.5 :-)

Kind regards,
