C++ vs Java

By | August 30, 2019

C++ and Java both support Object-oriented programming and has an approach for statically typed programming too. Though there are many similarities between Java and C++, still contain many distinctions too. There was a time when C++ and Java were fighting head to head for the number 1 programming language, because of the Object-Oriented programming support.

For a beginner, it is always a tough choice to select a programming language between C++ and Java, but most of the time it suggested that C++ is an Ideal language for beginners because it is a not a pure Object-Oriented language.

Here in this article, we have provided a simple comparison between C++ and Java so a beginner can opt between these two programming languages. Before we compare both the languages let’s have a brief introduction of each.

C++

C++ is a high-level programming language with multi-paradigm such as Object-Oriented, General Purpose and Procedural Programming. It is developed by Bjarne Stroustrup at Bell Labs as an Extension of C programming language.

It is a procedural language which means it executes code line by line and supports the function structure programming. Apart from Procedural oriented programming C++ focused on Object-oriented programming which helps a lot to solve real-time-based problems.

It is also a statically typed language which mean for every variable we have to define its data type. C++ is also popular for designing graphical applications. When we compare C++ with Java syntax, both almost follow the same syntax.

Java

Java is also a High-Level programming language developed by Sun Microsystem, it is a pure object-oriented programming language which is basically used to build software for different Operating systems.

Like C++ Java is also a statically typed programming language and shear almost the same syntax as C++. Java uses the compiler to compile its source code to bytecode and this bytecode is platform-independent.

Java vs C++: Head to Head Comparison

Java

C++

Programming Type

Object-oriented programming language.

Procedural as well as Object-oriented programming language.

Translator tools

Java use Compiler as well as interpreter to execute its source code

C++ only uses Compiler to execute its source code

Operator Overloading

In operator overloading, we can alter the functionality of Operator such as +, *, – etc. and Java does not have inbuilt support for Operator overloading.

C++ has support for Operator Overloading

Multiple Inheritance.

In Multiple Inheritance, the property of one class can be inherited by many classes and Java does not support multiple inheritance.

In new updates of java, it provides some support for multiple inheritance.

C++ support full multiple inheritance.

Build Applications

Java is used to build applications for different operating systems

Whereas C++ is limited to build windows exe applications.

Libraries

Libraries are the pre-written codes that a user can use in its program for more productivity and Java has many libraries

C++ doe not have many libraries as Java

Learning Curve

Learning Java is more difficult than C++

C++ is easy to learn if we compare it with Java.

Pointer

Java does not have pointers.

C++ uses the pointer to store the memory address of variables.

Threads

Java comes with in-built thread class that can be inherited in working-class

C++ does not have thread concept.

Interoperability with other programming languages

There is no backward compatibility in Java, but it follows the interoperability with Scala programming language.

C++ can interoperate with C language with some syntax changes.

Principle

Write once run anywhere everywhere

Write once run anywhere

Code execution

Source code gets compiled with compiler and gets converted into bytecode, then the byte code is executed by Interpreter.

Source code is compiled by the compiler and get executed.

Memory Management

Java Compiler automatically controls the memory.

User can control memory manually

Scope resolution

There is no scope resolution (::) in Java to access a global variable.

C++ has a scope resolution concept.

Destructor

Java compiler handles all the memory management so there is no concept of destructor

In C++ user have access over memory so it has the concept of Destructor.

Portability

Once the source code is compiled and we have a bytecode, we can run it on any platform which has Java Virtual Machine without compiling every time.

We have to compile the C++ source code every time if we try to run it on the system or platform.

Inbuilt-Structure

Java has Threads and Interface

Whereas C++ has structure, pointers and union

Polymorphism

Java automatically uses static and Dynamic Binding.

User has to explicitly assign syntax for dynamic bunding.

Conclusion:

Both programming language shear almost the same syntax for many important statements. There is no prerequisite to learn these languages and both are ideal languages for a beginner, even though we suggest you to learn C++ first because it covers procedural programming which helps you to build logic and make you understand how the flow of programs work.
