There are many programming languages available and
each of them is suitable for another program or application. There are
people who have learnt only a few programming languages and who use
these because that is what they know, bust most of the times software
programmers will use the programming language that is required by the
application they are creating. Java is one of the most frequently used
programming language and writing in this language is somehow different
from the usual Pascal or any C/C++ version but that does not mean that
learning the java code is harder than learning Pascal or C++. Nowadays
there are numerous applications written in Java and its terminology it
may seem a bit harder in the beginning but anyone can write in this
programming language, that's for sure.
When looking into a new
programming language, most people would like to know if it is easy to
learn and work in. If you compare it to C or C++, you may discover that
indeed, using it can be more straight forward. This is due to the fact
that Java has far fewer surprises compared to C versions. C and C++
make use of a lot of peculiarities so learning and mastering them all
can be a daunting task (for example, temporary variables hang around
long after the function that created them has terminated). Being more
straight forward, Java is a bit easier to learn and to work with. Java
eliminates explicit pointer dereferences and memory
allocation/reclamation, for example, two of the most complicated
sources of bugs for C and C++ programmers. Out of range subscripts are
easy to find, as Java is able to do add array bounds checking. Others
may argue that it seems easier to work with because there are very few
examples of extremely complicated projects done using it, but the
general accepted idea is that it is somehow easier to master than C or
C++.
Learning Java programming is not very difficult, especially
if you are familiar with other, more basic, programming languages and
you know for sure what you want to create using it and it has a series
of benefits compared to C and C++. First of all, code written in this
programming language is portable. Code written in C and C++ is not and
this makes Java more practical (for example, in C and C++, each
implementation decides the precision and storage requirements for basic
data types.
When you want to move from one system to another,
this is a source of problems because changes in numeric precision can
affect calculations). On the other hand, Java defines the size of basic
types for all implementations (for example, an "int" on one system is
the same size and it represents the same range of values as on every
other given system). Find out more at

The cases of programs
that make use of floating point arithmetic requires a special
attention: a program that uses floating point calculations can produce
different answers on different systems (in this case, the degree of
difference increases with the number of calculations a particular value
goes through). But this is a thing specific to all floating point code,
not only Java code which is also more portable then C or C++ in its
object code. It compiles to an object code for a theoretical machine -
in other words, the interpreter emulates that machine. This translates
to the fact that code compiled on one computer will run on other
computer machines that has a Java interpreter, but more on this subject
you will find out while learning Java programming.
