}
}
public static void main(String[] args)

推荐答案
据我记得,雅虎没有免费提供对SMTP主机的直接访问.你得付钱.不像谷歌.通常,我将gmail帐户用于此类实现.
As far as I remember Yahoo not provide direct access to SMTP host, free. You have to pay. Not like google. Normally I use gmail account for these kind of implementation.
您能显示一下MailClient.java中第94行的内容吗?我的意思是全部吗?
Can you show what you have on line 94 in MailClient.java. I mean is this all?
您是什么意思?在第94行中,它调用函数"sendMail",然后该函数发送邮件
what do you mean? in line 94 its calls a function "sendMail" and that function send mail
