Difference Between C++ vs Java
There are so many differences and similarity given below between the Java Programming Language and C++ Programming (Java vs C++).
|1.||Platform||C++ is a platform-dependent||Java is a platform-independent|
|2.||Platform Scope||It cannot run on different platforms, once it compiled.||Write Once Run Anywhere (WORA) – Due to JRE and Byte code, it can be able to run on any platforms.|
|3.||Origin||Based on C.||Based on C++ and C.|
|4.||Relationship||C++ was designed to solve a different set of problems. Mainly used for system programming.||Java was not designed to replace C++. Java is mainly used for application programming.|
|5.||Compiler and Interpreter||C++ uses compiler.||Java uses compiler as well as interpreter.|
|6.||Concepts||C++ is a partial or semi Object-Oriented Language.||Java is full Object-Oriented Language.|
|7.||Multiple Inheritance||C++ support multiple inheritances.||Java doesn’t support multiple inheritances because the subclass gets the ambiguity.|
|8.||Scope resolution operator||C++ support scope resolution operator (::)- A Scope operator is used to defining a method outside the classes and is also used to access the global variable inside the method that contains the local variable with the same name.||Java doesn’t support it.|
|9.||Overloading||C++ has both features, method overloading as well as operator overloading.||Java support only method overloading.|
|10.||Threads Supports||C++ doesn’t support any built-in thread mechanism. Third-party libraries need to support threads in a program.||Java supports built-in threads. Import java.lang.Thread inorder to use threads.|
|11.||Pointers||C++ supports pointers, which points to the address.||Java doesn’t support pointers because of security reasons, if you get the address of any variable then it can be able to breach the security.|
|12.||Call by value or Call by reference||C++ support both call by value as well as call by reference||Java doesn’t support the call by reference because java doesn’t support pointers. It supports only call by value .|
|13.||Preprocessor directives||Preprocessor directives (#) is use to include the libraries, C++ support Preprocessor directives e.g #include<iostream>.||Java doesn’t uses Preprocessor directives to include the libraries or class, It uses the import keywords to import any packages e.g import java.util.Scanner;|
|14.||Memory Management||C++ uses the manual memory management using Mallac(), Realloc(), Calloc(), Free(), and etc.||Java support automatic memory management system known as Garbage Collection.|
|15.||Intermediate Code||C++ doesn’t generate any byte code (intermediate code) after compilation. C++ generates executable native codes.||Java generates a byte code (intermediate code) after compilation.|
|16.||Is Case Senstive?||Yes||Yes|
|17.||Representation of Strings||C++ represents the strings in the form of Array.||Java represents the strings in objects.|
|18.||Output Format||Using std libraries, Syntax :
|It uses the print() function of System.out class System.out.print(“Codenaive”);|
|19.||Code Execution||Direct execution by Operating System.||Code is excuted by JVM (Java Virtual Machine ).|
|21.||Sandbox Model||Not Supported||Supported due to JVM.|
|22.||Templates||Templates are the most powerful features in C++.
e.g template <typename T>
|Java doesn’t support templates.|
|23.||File Extension||.cpp is used as extension for C++ program, e.g hello.cpp.||.java is used as extension, e.g hello.java.|
|24.||Unions||It supports Unions.||Java doesn’t support Unions.|
|25.||Structures||C++ support Structures.||Java doesn’t support Structures.|
We learn in this tutorial, how java is related to C++, what is the difference between C++ vs Java. Now, we know that both languages have their own importance at various aspects of features. As discussed, c++ is better in system programming e.g Kernal( creates by C/C++) whereas java is better in an application programming language.
