1. Brief history of Java?
Ans:
Java history is interesting to know. The history of java starts from
Green Team. Java team members (also known as Green Team ), initiated
a revolutionary task to develop a language for digital devices such as
set-top boxes, televisions etc.
For the green team members, it was an advance concept at that time.
But, it was suited for internet programming. Later, Java technology as
incorporated by Netscape.
Currently, Java is used in internet programming, mobile devices, games,
e-business solutions etc. There are given the major points that describes
the history of java.
1) James Gosling , Mike Sheridan , and Patrick Naughton initiated
the Java language project in June 1991. The small team of sun engineers
called Green Team.
CO1 High Evaluating
2) Originally designed for small, embedded systems in electronic
appliances like set-top boxes.
3) Firstly, it was called "Greentalk" by James Gosling and file extension
was .gt.
4) After that, it was called Oak and was developed as a part of the
Green project.
5) Why Oak? Oak is a symbol of strength and choosen as a national
tree of many countries like U.S.A., France, Germany, Romania etc.
6) In 1995, Oak was renamed as "Java" because it was already a
trademark by Oak Technologies.
2. Explain about java programming Language with example
Program?
Java is a programming language and a platform. Java is a high level,
robust, secured and object-oriented programming language.
Platform : Any hardware or software environment in which a program
runs, is known as a platform. Since Java has its own runtime
environment (JRE) and API, it is called platform.
Example:
1. class Simple{
2. public static void main(String args[]){
3. System.out.println("Hello Java");
CO1 High Creating
10. High Performance
11. Multithreaded
12. Distributed
4 Explain about Fundamentals of Object-oriented Programming
Language?
Object-oriented means we organize our software as a combination of
different types of objects that incorporates both data and behaviour.
Object-oriented programming(OOPs) is a methodology that simplify
software development and maintenance by providing some rules.
Basic concepts of OOPs are:
1. Object
2. Class
3. Inheritance
4. Polymorphism
5. Abstraction
6. Encapsulation

5 How Java is Platform Independent Explain?
A platform is the hardware or software environment in which a program
runs.
There are two types of platforms software-based and hardware-based.
Java provides software-based platform.
The Java platform differs from most other platforms in the sense that it
is a software-based platform that runs on the top of other hardware-
based platforms. It has two components:
1. Runtime Environment
2. API(Application Programming Interface)
Java code can be run on multiple platforms e.g. Windows, Linux, Sun
Solaris, Mac/OS etc. Java code is compiled by the compiler and
converted into bytecode. This bytecode is a platform-independent code
because it can be run on multiple platforms i.e. Write Once and Run
Anywhere(WORA).

6 Discuss about how java is Secured?
Java is secured because:
• No explicit pointer
• Java Programs run inside virtual machine sandbox
CO1 High Evaluating
Mainly used for
C++ is mainly used for system programming.
Java is mainly used for application programming. It is widely used
in window, web-based, enterprise and mobile applications.
Goto
C++ supports goto statement.
Java doesn't support goto statement.
Multiple inheritance
C++ supports multiple inheritance.
Java doesn't support multiple inheritance through class. It can be
achieved by interfaces in java.
Operator Overloading
C++ supports operator overloading.
Java doesn't support operator overloading.
Pointers
C++ supports pointers. You can write pointer program in C++.
Java supports pointer internally. But you can't write the pointer
program in java. It means java has restricted pointer support in
java.
Compiler and Interpreter
C++ uses compiler only.
Java uses compiler and interpreter both.
Call by Value and Call by reference
C++ supports both call by value and call by reference.
Java supports call by value only. There is no call by reference in
java.
Structure and Union
C++ supports structures and unions.
Java doesn't support structures and unions.
Thread Support
C++ doesn't have built-in support for threads. It relies on third-
