Similarities and Difference Between Java and C++ 2022
31st October 2022
Java and C++ programming languages are now widely employed in competitive coding. These two programming languages are also frequently employed in businesses due to some amazing characteristics.
C++ is a popular programming language due to its efficiency, speed, and dynamic memory utilization Java is widely used in the IT industry.
In terms of software development, it is unrivaled by any other programming language. Let us compare these prominent coding languages at various points:
Similarities between Java and C++
1. Execution: Java source code, or.java files, are translated into bytecode. class if less, at compilation time.
At runtime, the JVM (Java Virtual Machine) will import the. class files and use an interpreter to transform them into machine code.
JVM will run the optimized code after compiling method calls (using the Just-In-Time (JIT) compiler).
As a result, Java is both a compiled and interpreted language. C++, on the other hand, executes code using simply a compiler.
The C++ compiler compiles the source code and turns it into machine code. As a result, while C++ is quicker than Java, it is not platform-independent.
The following diagram depicts how Java and C++ codes are executed:
Execution of a C++ Code
The following is how Java code is executed:
2. Features: Both C++ and Java include various Object Oriented programming features that enable a wide range of programming capabilities.
Some characteristics are supported by one, while others are supported by the other.
Even though both languages incorporate the concept of OOPs, neither can be considered 100% object-oriented.
Because Java contains basic data types, it cannot be considered a fully Object-Oriented language.
C++ has primitive-like data types and can implement methods without utilizing any data type. As a result, it is denied the claim of 100% Object-Oriented.
The table below indicates which features are available and which are not supported by both programming languages:

C++ and Java both have a wide range of applications. Both languages have the following applications:
-
C++ Programming Language Applications:
-
Suitable for Developing Large Software (like passenger reservation systems).
-
MySQL was created in C++.
-
C++ is often utilized in game development for its quick execution.
-
C++ is used to write the Google Chromium browser, file system, and cluster data processing.
-
Adobe Premiere, Photoshop, and Illustrator are all C++-scripted apps.
-
Real-time physical simulations and high-performance picture processing are examples of advanced computations and graphics.
-
C++ is also employed in many advanced medical devices such as MRI machines.
-
Java Programming Language Applications:
-
Development of Desktop GUI Applications
-
Development of Android and mobile applications
-
Java is used in embedded technologies such as SIM cards, disc players, televisions, and so on.
-
Java EE (Enterprise Edition) is a runtime environment and API for running large enterprise apps.
-
Internet connection, Web App Development are examples of Network Applications and Web Services.
Environment: C++ is a platform-dependent programming language, whereas Java is a platform-independent programming language. On the same platform, we must write and run C++ code.
Java offers the WORA (Write Once and Run Everywhere) functionality, which allows us to write our code once and run it anywhere.
The following are the distinctions between Java and C++:

Influenced B: |
Java was Influenced by Ada 83, Pascal, C++, C#, etc. languages. |
C++ was Influenced by Ada, ALGOL 68, C, ML, Simula, Smalltalk, etc. languages. |
|
Influenced to: |
Java was influenced to develop BeanShell, C#, Clojure, Groovy, Hack, J#, Kotlin, PHP, Python, Scala, etc. languages. |
C++ was influenced to develop C99, Java, JS++, Lua, Perl, PHP, Python, Rust, Seed7, etc. languages |
|
Pl artform Dependency |
Platform independent Java bytecode works on any operating system. |
Platform dependent should be compiled for different platformsportability |
|
Portability |
It can run on any OS hence it is portable. |
C++ is platform-dependent. Hence it is not portable. |
|
Compilation |
Java is both a Compiled and Interpreted Language. |
C++ is a Compiled Language. |
|
Memory Management |
Memory Management is System Controlled. |
Memory Management in C++ is Manual. |
|
Virtual Keyword |
It doesn’t have a Virtual Keyword. |
It has Virtual keywords. |
|
Multipleinheritance |
It supports only single inheritance. Multiple inheritances are achieved partially using interfaces. |
It supports both single and multiple Inheritance. |
|
Overloading |
It supports only method overloading and doesn’t allow operator overloading . |
It supports both method and operator overloadingPinterest |
|
Pointers |
It has limited support for points. |
t strongly supports libraries |
|
Libraries |
It doesn’t support direct native library calls but only Java Native Interfaces. |
It supports direct system library calls, making it suitable for system-level programming. |
|
Libraries |
Libraries have a wide range of classes for various high-level services. |
C++ libraries have comparatively low-level functionalities. |
|

|
Type |
Java is only an object-oriented programming language. |
C++ is both a procedural and an object-oriented language. |
|
InputOutputt mechanism |
Java uses the (System class): System .in for input and anSystemem.out for output. |
C++ uses cin for input and cout for an output operation . |
|
goto Keyword |
