Difference Between C and Java


Main Difference

Although Java is derived from C and C++ and many of its syntactic characteristics are like C but still there are many huge differences between these two. The real difference between these two programming language exists on the basis of their usage. C is a function oriented language while Java is an object oriented language. We can say that C is more procedure-oriented language while Java is a data-oriented language.

What is C Language?

C is an old system programming language developed by Dennis Ritchie in 1969. C has been accepted as an easy, flexible and powerful language used for programming of many applications, either it is for engineering programs or business programs. It was the upgraded version of B language of that time. UNIX operating system was the first operating system written in C and latest operating system like Windows and Linux, are also written in C language. Many computer architectures and operating systems are using this language. The advantages of C language are that it is a most reliable, portable, flexible, efficient, effective and interactive programming language. It is widely used in developing database systems, word processors, spreadsheets and operating system developments. At present 19% of the programs are developed in C programming language.


What is Java Language?

Java is a general purpose and object-oriented programming language (computer) that was designed by James Gosling and Sun Microsystems and was first appeared in 1995. The unique thing about Java is that it is a WORA language that allows the developers to “write once, run anywhere” (WORA). That means the compiled code of Java can run easily on all supported Java platforms by surpassing the need of recompilation. Applications of Java are typically compiled to bytecode that can run on any Java Virtual Machine (JVM) regardless of computer function and system. By now, 2015, Java is one of the most popular and widely used programming languages that are mostly used by developers for client-server web applications. As of 2015, nine million developers of Java have been reported. Although Java is derived from C and C++ and many of its syntactic characteristics are like C and C++ but it still has low-level facilities than either of them.


Key Differences

  1. C is a procedural and function oriented computer programming language while Java is an object oriented computer programming language.
  2. C is a compiled language while Java is an interpreted language.
  3. Java is derived from C as most of its syntax are derived from C and C++. Java is dependent on C while C is independent.
  4. Although syntax characteristics of Java are derived from C but still it is a more high-level language.
  5. C users the top-down (sharp & smooth approach) while JAVA uses the bottom-up (on the rocks) approach.
  6. Method Overloading is also the difference between these two languages. Java supports the Method Overloading that is not supported by C at all.
  7. Preprocessors are supported by C not by Java at all.
  8. Java can handle the errors and any interruptions by using exception handling techniques while C is not good in handling errors.
