Java Vs C++ Difference And Comparisons

Comparison and Difference between Java and C++

Before advent of Java, C++ was very popular and most widely used object oriented programming language. Bjarne Stroustrup developed C++ in the year 1979. Java when comes to syntax, it is quite similar to C++. Java and C++ has many major differences. Java left out C++ complex concepts, modified and added new.

Let us examine few of major differences between the two :-

1. Java is pure object oriented programming language, while C++ supports both procedural and object oriented approach.

2. Java does not support multiple inheritance, while C++ supports multiple inheritance.

3. Java does not support

operator overloading, while C++ supports operator overloading.

4. In Java, methods are part of the class, while C++ has stand alone methods which are not part of class.

5. In Java, objects are passed to methods only by reference, while in C++, objects can be passed to functions by value or reference.

6. Java doesn’t support pointer mechanism, while C++ uses pointers extensively.

7. In Java, Strings are objects, while in C++, Strings are null-terminated character arrays.

8. Java has built in string concatenation operator, while in C++ all string operations are performed using functions.

9. Java doesn’t support Templates, while C++ supports Templates for parameterized type.

10. Java doesn’t support default arguments, while in C++ functions can take default arguments.

11. In Java, methods are dynamically bound, while in C++ only virtual functions are dynamically bound.

12. In Java, array lengths in multidimension can vary from one element to the next within one dimension, while in C++ multidimensional arrays lengths are of same sizes.

13. In Java, there is bound checking on the arrays, while in C++ there is no bound checking.

14. Java supports automatic garbage collection, while in C++ there is no automatic garbage collection.

15. Java is a

compiled and interpreted language, while C++ is a compiled language.

16. Java has no functionality of structures and unions, while C++ has structures and union.

17. Java doesn’t supports forward referencing, while C++ supports explicit forward referencing.

18. No typedef in Java, while C++ supports typedef.

19. Java provides documentation comments which is missing in C++.

20. In Java, main method doesn’t return any value, while in C++ it can return values.

21. Java supports labels on break and continue statements, while in C++ there is no label functionality.

22. Java is architectural neutral programming language, while C++ is specific to particular architecture.

23. Java supports interfaces which is missing in C++.

24. Java supports multithreading which is missing in C++.

25. No preprocessor is required in Java, while C++ rely on preprocessor.

26. In Java, program name is not included for command-line arguments, while C++ includes the program name.

27. Java supports web based applications such as JSP, servlets and applets, while C++ lacks such feature.

28. Java supports distributed applications such as RMI and sockets, while C++ lacks this functionality.

29. Java also supports network protocols such as TCP/IP and HTTP, while C++ lacks those supports.
