programming language was introduced in the year 1995 with the launch of this particular
paper which is being used as a reference to get a better understanding about
the widely used and wildly popular programming language.
the creator of Java started working on this project after he was dissatisfied with
the improvements made in C++ language as it had many shortcomings same as its
predecessor C. He along with two other programmers started working on project

became widely popular after its launch because of its nature of “Write Once, Run Anywhere” as its code executes
in its own virtual environment. The bytecode once created after compilation in
one particular system can be used to execute the
program in any system
having the virtual environment provided by Java.
The need for Java:
Developers in the late 90’s started to understand
the importance of the Internet and how it is going to change application
development process forever. They knew they had the means to share the code
between different systems present across a network but the code they developed
was platform and architecture dependent. Java provided them a means to share
and execute the code across all the platforms and architectures. Uploading the
compiled bytecode onto a server allowed the code to be executed securely onto
all the connected virtual machine environments. This made sure that the code
sharing was secure, and that the resources utilized for compiling the program
Why shift to
Java from your current language?
With the introduction of C++,
programmers got to know about object-oriented programming and all of its
advantages. Java being able to offer all the advantages of C++ and then some more
made it a tough choice to not to give it a try. C being made decades ago before
the introduction of Java did not have the security features to run on a
and the syntax were made to make the programmers task so easy that there would
be a very minimal learning curve for anyone starting to code in Java.
With Java being very similar to C++, programmers who are
or have a working knowledge of widely popular C and C++ were able to weigh the
pros and cons of the new language and create more portable applications with
much less debugging required before the deployment of the application. The
applications were more consumer friendly with Java being more secure from outside
code changes i.e. third-party users or applications cannot change the already compiled
byte code of the Java Development Environment.
once hosted can be downloaded from across the web. The web-browser HotJava was
the first to implement Java environment. It allowed dynamic downloads and
execution of Java fragments or applets from across the Internet. Making it
platform independent was a huge break-through compared to C and C++ as
developers had to develop individual programs for every platform and every
architecture. Applications running on a 32-bit system were not compatible with
64-bit system unless they have their code through JVM (Java Virtual Machine).
is portable and adaptable to multiple environments allowing developers to
simultaneously work on a project from different systems and even different
Operating Systems. This foundational idea of running apps on a Virtual
Environment is being currently used in Android allowing it to be used in billions
of devices across the world.
ability to link classes only when needed and multi-threading make it faster
than all other alternatives allowing it to run multiple instances of a program
simultaneously. A application can update itself in the background while the
user is using the application. This is a important feature for the creators as
end-users rather skip the update than waiting for the application update to be
Multi-threading allows multiple concurrent threads to be executed
simultaneously making their execution much faster and robust. Having multi-threading
also implies taking care of multiple libraries being accessed at the same time.
Java’s libraries have been written to take care of this issue.
Distributed Computing concept has been made a reality with Java. The
ability to share one’s code to be executed on any environment meant that a huge
workload can be across multiple devices and be executed faster. This made its
way into the concepts of Grid Computing and eventually into Cloud Computing. Performance
of the systems was vastly increased because of the decrease in compilation resources.
Is Java Really Simple and Familiar?
Java, filling in the voids from C++
initially started to be made as an Operating System. It has its roots from many
familiar languages during the 90’s like SmallTalk and Objective C.
implemented the concept of multi-threading and object-oriented programming to
make it a better alternative to C++ but retained its syntax to make it easy to
Programmers who were already writing
code in C++ quickly became familiar with the syntax of java and started
deploying applications to test their new dynamic code. With removal of all the
features that made applications made in C++ crash, Java applications quickly
skyrocketed into development and then into deployment.
C and C++ had a huge issue with
providing access to Operating System through pointers and Garbage values which
was completely prevented in java through Garbage collectors and reference
Java has no
operator overloading, no structures, no pointers, no pre-processors. All the
things that made it difficult for one programmer understand the functionality
of a program have been removed to make it simple. A single ‘goto’ statement can
completely disrupt the flow in C++ which was completely eliminated in Java. Making
a complicated program doesn’t necessarily mean that it has to be complicated
for another user to understand. These features of C++ complicated things paving
way for a better and faster programming language.
was not a solution to all the problems that programmers face but it sure did
solve many that C++ had. It’s implementation of Distributed Computing has made
it a better solution than many alternatives and the ability to run across any
device still keeps it relevant. It came prepared with multiple features like
multi-threading and garbage collectors to keep it at the top of the game during
