有两个java类都具有main函数.现在我必须首先将第一类对象调用到第二类对象和第二类对象.每当我这样做它就会给出堆栈溢出异常.有没有办法同时称呼这些？

头等舱:

     MD5Generator pass = new MD5Generator(); 
     PopUp popobj = new PopUp();
     ForgotPassword fpemail = new ForgotPassword();

二等:

    Connection con = null; 
    Statement stmt = null;
    ResultSet rs = null;
    String message = null; 
    String useremail; 
    PopUp popobj = new PopUp(); 
    RandomStringGenerator rsg = new RandomStringGenerator(); 
    MD5Generator …
