2. INRODUCTION
 JAVA – Java is an object –oriented programming language that produces software
for multiple platforms . When a programmer writes a Java application, the
complied code (known as bytecode) runs on most operating systems (OS) ,
including Windows , Linux and MAC OS . Java derives much of its syntax from the C
and C++ programming language
 C – C is a powerful general –purpose programming language . It can be used to
develop software like operating systems , databases , compilers and so on . C
programming is language to learn program for beginners .

3. HISTORY
C was developed by Dennis M. Ritchie
between 1969 and 1973 . C was originally
developed for UNIX Operating Systems to
beat the issues of previous language such
as B , BCPL , ETC.
Java was created at Sun Microsystems . It was
originally designed for interactive television ,
but it was too advance technology for the
digital cable industry at the time . The
principles of Java programming were “Simple ,
Robust , Portable , Platform-independent ,
Secured , High Performance , Multi-threaded ,
Architecture Neutral , Object-Oriented ,
Interpreted and Dynamic” . Java is developed
by JAMES GOSLING , who is known as father of
java , in 1995 . Java developing was started in
early 90s .

4. KEY FEATURES OF JAVA
 One of the most interesting and important features which Java supports is the WORA –
Write Once Run Anywhere – features . Once compiled , Java code can be run on any
computing platform . For example , if a code has been written on a MAC Operating
system , the same code can be run on a WINDOWS Operating Systems without any
trouble if the Windows operating system has JVM(Java Virtual Machine) installed on it .
 Java is purely an Object-Oriented-Programming Language , that’s why , all Java codes
are always written in the form of classes and objects .
 Java is a multi-threaded language with automatic memory management . It has great
features for garbage collection and is heavily used for distributed computing because of
its network – centricity .
 Java is dynamic and extensible .
 Java is also secure and robust .

5. KEY FEATURES OF C
 C is a structured programming language that is extremely easy to learn .
 It is an efficient programming language , it is fast and has very good performance .
 C is a highly portable and extensible programming language because it is not tied to
any hardware or systems . Any code written in C can be run on any machine which
supports C , without modifying a single line a code .
 C has a rich set of built-in Operators and libraries with functions .
 C is modular and statically typed .
 C is a Procedure Oriented Programming language (POPs) .
 C is a high level language with low level features .

6. LANGUAGE TYPE
C language
 C is a procedural programming
language .
 C is more procedure - oriented .
 C is a middle – level language
because binding of the gaps takes
place between machine – level
language and high – level languages .
JAVA language
 Java is an Object-Oriented
language .
 Java is more data-oriented .
 Java is a high – level language
because the translation of code
takes place into machine language
using a compiler or interpreter .

7. PROGAMMING PARADIGMS AND OBJECT MANAGEMENT
 C is generally breaks down to
functions .
 It is more procedure oriented .
 In C one has to manage object
manually .
 Java breaks down to Objects .
 It is more data-oriented .
 In Java object is automatically
managed by the garbage collector .

8. MEMORY ALLOCATION
 Memory allocation can be done
by malloc.
 For freeing the memory one has
to use free .
 Memory allocation can be done
by a new keyword .
 Compiler will do it internally by
calling the garbage collector
c Java

9. CALLING FUNCTIONALITY , VARIABLE DECALRATION &
KEYWORDS
 It supports call by value and call
be reference .
 Declaration of variables should
by at the beginning of the block .
 It has 32 keywords .
 It only supports the call by value .
 We can declare variables
anywhere through it is a good
practice to declare the variables
at the beginning of the block .
 It has 50 keywords .

10. DIFFERENCE BETWEEN JAVA AND C
V
 It is based on Write Once Compile
Anywhere .
 C is only compiled and not interpreted .
 C has support for pointers .
 C follows a top-down approach .
 C is not a robust programming language .
S
 It is based on Write Once Run Anywhere
.
 Java is both compiled and interpreted .
 Java does not supports pointers .
 Java follows a bottom – up approach .
 Java is a robust programming language
as it has strong memory management
schemes .
