language.
C Programming is not an object
oriented language
2. Java does not support
pointers.

No.
JAVA C++ Programming
1. Java is a true object oriented
language.
C++ is basically c with object
oriented extension.
2. Java does not support
operator overloading.
C++ support operator overloading.
3. Java does not support
multiple inheritance.
C++ support multiple inheritance.
4. Java does not use pointers. In c++, we can use pointers.
5. Java does not support global
variable.
C++ support global variable.

6. Java and internet
• Java is strongly associated with internet.
• First application program written in java is
“HOTJAVA” (a web browser).
• Support to Internet Protocols: Java has a rich
variety of classes that abstracts the Internet
protocols like HTTP , FTP, IP, TCP-IP, SMTP, DNS
etc.
• Applets in java are used to provide interactive
features to web applications.

7. Java and World Wide Web
• Java and World Wide Web are based on
same philosophy i.e. to be used in
distributed environments such as internet.
• Before java, World Wide Web is only able to
show Still images and text.
• With the support of java World Wide Web
become more interactive.

8. Web Browsers
• Web Browser are used to navigate through the
information found in the internet.
• They allow us to retrieve information from the
internet.
• Examples of web browsers are:-
• Hot java, Netscape Navigator, internet Explorer.

9. Supported Systems, Hardware
and Software Requirements
• Java is currently supported on following
machines:-
• Windows, Linux, Mac OS X
• The minimum hardware & software
requirements for Windows XP SP1+ on Java:-
• RAM: 128 MB, 64 MB for Windows XP (32-bit)
• Disk space: 1GB
• Browsers: Internet Explorer 7.0 and above,
Firefox 3.6 and above, Chrome.

10. Java Environment
• Java Environment includes a large number of
development tools, hundreds of classes and
methods.
• Development tools are the part of system known as
JAVA DELOPMENT KIT(JDK).
• Methods and classes are the part of JAVA
STANDARD LIBRARY(JSL) or API.
