The example in this article describes the Java implementation method for sending mail based on SMTP. Share to everyone for your reference. The implementation method is as follows:
Import Java.util.Date;
Import java.util.Properties;
Import Javax.mail.Authenticator;
Import Javax.mail.Message;
Import javax.mail.PasswordAuthentication;
Import javax.mail.Session;
Import Javax.mail.Transport;
Import javax.mail.internet.InternetAddress;
Import Javax.mail.internet.MimeMessage;
Import Org.apache.lo
so on.
State Diagram
objects have behavior and status. The state of an object is determined by the current action and condition of the object. The state diagram Statechart diagram shows the possible state of the object and the transitions caused by the state change.Our model diagram establishes a bank's online login system. The login process involves entering a valid password and personal account and submitting it to the system for verification information.
The login system can be divided into

vulnerable connections (that is, passwords) for authentication systems. The industry is in great need of technology that can replace passwords. With embedded cryptographic processors, smart cards provide a very secure and easy-to-use authentication mechanism.
However, the deployment of smart cards also poses a unique challenge. The entire industry needs better products to deploy and manage complex authentication technologies. In his keynote address at the RSA 2006 Conference, Bill Gates demons

UML 2.The most important innovation in interactive modeling. The original sequence diagram is organized into a complex sequence diagram. Because of these, you can combine (reuse) Simpler sequences to generate more complex sequences. ThisIt means you can abstract a complete, possibly complex sequence into a single conceptual unit.
