Two Way Chat

In two way chat we have two programs one is a server and the other is a client

Here in server program we create a server socket with a port of 6789(can be changed) by usingser=new ServerSocket(6789); and socket is connected to it by using socket=ser.accept(); Also we create inputstream reader and outputstream reader in the server.java file

In client we create a socket and connect it to the port number 6789 by using  socket=new Socket(InetAddress.getLocalHost(),6789); Also we create inputstream reader and outputstream reader in the client.java file

 For running the Chat we have to run server using a one command prompt and client using another command prompt.

Analogue Clock

 This is a program for creating Analogue Clock using applet. An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included in a page. When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser's Java Virtual Machine (JVM). For information and examples on how to include an applet in an HTML page.

For this we need two files one java file and one html file. In the java file the below program should be pasted and should save as "Clock.java" and html file you have to include the program given bellow
