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 both procedural and 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++?

C++ (Cee Plus Plus) is a multi-prototype, procedural, object-oriented, generic, and functional programming language that also provides the facilities for low-level memory manipulation. It was designed by Bjarne Stroustrup and was initially released in 1983. Latest version of C++ was released on December 15, 2014. C++ is an accumulated language that is used in many platforms and many organizations like FSF, LLVM, Microsoft, and Intel are using this language. It is considered as the recommended programming language to strengthen the software infrastructures and resource-constrained application such as desktop applications, servers (includes e-commerce, web search and SQL servers), performance critical applications (includes telephone switches or space probes), and entertainment software.


What is Java?

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 WOCA means Write once, compile anywhere while Java is WORA means Write once, run anywhere.
  2. Java only runs in virtual machine while C++ runs as a default executable machine code for the target instruction sets.
  3. C++ supports many programming features like unions, templates, operator overloading, structures, and pointer arithmetic while all these are not supported by Java.
  4. The main feature of C++ is conditional inclusion like #ifdef and #ifndef type while Java totally doesn’t support conditional compilation and inclusion.
  5. Java only supports overloading while C++ supports both overloading and operator overloading.
  6. Java is derived from C++ as most of its syntax are derived from C++. So, Java is dependent in C++ while C++ is independent.
  7. Java doesn’t provide global variables while C++ is good at providing global variables.
  8. C++ provides header files that are not being provided by Java.
  9. C++ mainly focus on execution efficiency while Java mainly focus on developer productivity.
  10. C++ is has powerful capabilities of language while Java is feature-rich and has easy to use standard librabry.
