Similarities and Difference Between Java and C++

Java and C++: Find the Similarities and Difference Between Java and C++

Both of these are programming languages that we mostly utilize in competitive coding and various other industries due to the range of features they offer. C++ is pretty popular among various coders because it is very efficient, utilizes memory dynamically, and works at a great speed. Java, on the other hand, is most popular in the IT sector because it offers an incomparable software development service to all of its users.

What is C++?

It is a computer programming language, and it contains the features of both- the C programming language and Simula67 (it is the first object-oriented language). The concept of Objects and Class came into existence with C++. It means that it encapsulates both- low-level and high-level features. Thus, it acts as a language of the intermediate level. This language was previously known as C with Classes since it came with all the properties contained in the C language.

What is Java?

Sun Microsystems developed this programming language. A team of software developers worked on developing it. These people were called the Green Team, and they initiated this language in 1991.

Similarities Between Java and C++

They are both very popular and successful programming languages. There are various ways in which both of these differ, but there are also various similarities between them. Here are some of them:

  • Both the languages support object-oriented programming.
  • They have the very same type of syntax.
  • The comments syntax is identical between Java and C++.
  • The conditional statements (such as switch, if-else, etc.) and loops (such as for, while etc.) are similar among them both.
  • The relational and arithmetic operators are the same for both of these.
  • The execution of both of these programs begins from the main function.
  • The primitive data types are the same in both.
  • They both have various similar types of keywords.
  • They have multi-threading support.
  • They have pretty similar areas of applications.

Difference Between Java and C++

Here is a list of the differences between Java and C++.

Parameters

Java

C++

First Release

The Java language came into existence on 23rd May 1995.

The C++ language first came into existence in October 1985.

A stable form of Release

The JDK 14 or Java SE was finally released on 17th March 2020.

The C++ 17 was released back in December 2017.

Founder

James Gosling developed Java at Sun Microsystems.

Bjarne Stroustrup developed C++ at Bell Labs back in 1979 in the form of an extension to the C language.

Platform Dependency

The Java bytecode can easily work on any given OS (operating system). It is very much platform-independent.

The C++ language is platform-dependent. It means that we need to compile it for a different platform.

Official Website

The official website for Java is oracle.com/java

The official website for C++ is isocpp.org

Influenced By

The C#, C++, Pascal, Ada 83, and many more languages have an influence on the Java language.

Smalltalk, Simula, ML, C, ALGOL 68, Ada, and many more languages have an influence on the C++ language.

Influenced To

The Java language gets influenced to develop the BeanShell, Python, PHP, Kotlin, J#, Hack, Groovy, Scala, C#, Clojure, and many more languages.

The C++ language gets influenced to develop the Seed7, Rust, Python, PHP, Perl, Lua, JS++, Java, C99, and many more languages.

Portability

It is a portable language. We can easily run Java on any given platform.

It is not a portable language. It is because the C++ language is platform-dependent.

Memory Management

It has system-controlled memory management.

It has a manual form of memory management.

Compilation

The Java language is both- interpreted as well as combined.

The C++ language is only a compiled language.

Virtual Keyword

Java does not contain a virtual keyword.

C++ contains a virtual keyword.

Overloading

Java only provides support for method overloading, and it does not come with operator overloading.

C++ provides support for both- operator overloading as well as method overloading.

Pointers

Java provides very limited support for pointers.

C++ provides strong support for pointers.

Multiple Inheritance

Java provides support only for single inheritance.

C++ can partially achieve multiple inheritance using interfaces. It provides support for both multiple as well as single inheritance.

Type

It is only an object-oriented type of programming language.

It is both- an object-oriented and a procedural programming language.

Global Scope

Java does not have support for global scope.

C++ provides support for both namespace scope and global scope.

Management of Objects

Java has automatic object management and also a garbage collection.

C++ uses delete and supports manual object management using new and delete.

Libraries

There is no support for direct native library calls. It uses the Java Native Interfaces.

C++ comes with support for direct system library calls. Thus, it is very suitable for system-level programming.

Unions and Structures

There is no support for Unions and Structures in Java.

There is support for Unions and Structures in C++.

Passing Parameter

Java provides support for only the technique of Pass by Value.

C++ provides support for both Pass by Reference and Pass by Value.

Thread Support

It provides support for documentation comment for source code (e.g, /**.. */).

It does not come with built-in support for threads. It depends a lot on the third-party threading libraries.

Documentation Comment

Java provides support for documentation comment for source code (e.g, /**.. */).

C++ does not provide any support for documentation comments for the source code.
