BUILD SUCCESSFUL (total time: 42 seconds)
我已经看到问题仅在于将值从一帧转移到另一帧。在Settings.java中接受用户名和密码的值并转移到SendEmail.java
答案 0 :(得分：1)
您有两个Settings类的不同实例 - 一个位于SendMail，另一个位于EmailClient。更改一个实例不会影响另一个实例。在SendMail中创建一个接受Settings实例的构造函数：
public SendMail(Settings settings) {
this.setfrm = settings;
initComponents();
}
并修改SendMail中EmailClient的初始化：
Settings set=new Settings();
SendMail sm=new SendMail(set);
public EmailClient() {
initComponents();
}
因此，您确保SendMail和EmailClient同时使用同一个Settings实例（有关更多信息，请参阅Java中的参考资料）。
答案 1 :(得分：0)
我在SendEmail.java中看到，你创建了一个新的Settings实例 - ＆gt;这样的用户名和＆amp;密码为空。
然后你启动SendEmail jframe并访问用户名＆amp;电子邮件 - ＆gt;失败。
我想你需要这样做：
- 您定义2个字符串变量来存储用户名＆amp;密码
在SendEmail jframe中，您有一个按钮可以打开设置jframe来设置您自己的用户名＆amp;密码 - ＆GT;更新已更改为用户名＆amp;密码在SendEmail :)
