Difference between C and Java

Main difference

Although Java is derived from C and C++ and many of its syntactical features are like C, there are still many huge differences between these two. The real difference between these two programming languages ​​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 a more procedure-oriented language, while Java is a data-oriented language.

What is the C language?

C is an old systems programming language developed by Dennis Ritchie in 1969. C has been accepted as an easy, flexible, and powerful language used for programming many applications, whether for engineering programs or business programs. It was the improved version of the B language of that time. The UNIX operating system was the first operating system written in C, and the latest operating systems, such as Windows and Linux, are also written in the C language. Many computer architectures and operating systems use this language. The advantages of the C language are that it is a more reliable, portable, flexible, efficient, effective and interactive programming language. It is used in the development of database systems, word processors, spreadsheets and operating system development.

What is the 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 procedure 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 is derived from C and C++. Java depends on C while C is independent.
  4. Although Java’s syntax features are derived from C, it is still a higher level language.
  5. C uses the top down approach (sharp and soft focus) while JAVA uses the bottom up approach (on rocks).
  6. Method overloading is also the difference between these two languages. Java supports method overloading that C does not support at all.
  7. Preprocessors are compatible with C, not Java at all.
  8. Java can handle errors and any interrupts using exception handling techniques, while C is not good at handling errors.
