Java SMTP Mail Sent Application

if you are getting an error : authentication failed, or gmail blocked login attempt, then you should enable the access for less secure apps in your account

 Some devices and apps use insecure sign-in technology to access your data.
Choosing Disable prevents these less secure devices and apps from accessing your Google Account.
Choosing Enable increases your chances of unauthorized account access but allows you to continue using these less secure devices and apps. Learn more

Access for less secure apps should be enabled

Bi direction java networking chat application source code

Two way Chatting example in java using tcp socket

Java Chat application using TCP java socket programing example.  The program communicates with other through port number 3000 and 2000, developer can change this to what ever they want. avoid using first 1024 reserved ports. The program search the other system by its computer name, so please provide the name correctly. The program is so simple, easy to understand. The interface here used is to create two variable for storing port number.  And explaining the code:  Getting user input as string, converting them to bytes, storing it in a variable then sent through datagram socket as datagram packets through a port number specified. On the other hand the program keep on listening to that port number, if a request comes through that socket , it will receive it as byte convert to string the display the message. JAVA thread is used for listening
