In this tutorial, we will understand the differences between C++ and Java along with similarities in C++ vs Java with example. Both are object-oriented programming languages.
What is C++?
C++ is a programming language that is derived from C. Earlier C++ also had the name "C with classes". This is because C++ was the first language to introduce classes and objects and also inherits all the properties of C. It also uses the support of SIMULA-67 (the 1st Object-oriented language). We mainly use C++ for application and system development. The founder of C++ is Bjarne Stroustrup.
What is Java?
Java is a pure object-oriented programming language that runs on a virtual machine. It is more secure and portable. It also has an interpreter and we mainly use it for application development. The founder of Java is James Gosling. The initial name of Java was OAK which was a failure. Later, it was acquired by Sun microsystems and now by Oracle corporation.
Similarities of C++ vs Java
Even though there are differences between C++ and Java, there are similarities as well.
Execution: Both are similar in terms of the execution process. The compiler converts the source code into machine code. Additionally, Java has an interpreter which uses the JVM for the execution of the compiled code.

Features: Both languages support many features of the OOPs concept. But still, there are few features that one language supports and the other does not.

Java is a programming language that is based on OOPs concepts (Object-oriented programming system). In other words, it uses objects to define the data and their behavior. This makes the code more flexible and increases the readability and helps to understand the code easier. In this tutorial, we will understand OOPs concepts in Java.
Characteristics of OOPs in Java
Advantages of OOPs Concepts in Java
- Reduces code redundancy
- Improves code readability
- Low development cost
- Improved software quality
- Faster product development
- Reusability of code
Challenges of OOPs in Java
- High learning curve
- Large program size
- Slow execution
Object
One of the important features of Object-oriented programming in Java is an object. An object represents a real-life entity which is an instance of a class. It contains both data and methods(behaviors). Objects have mainly 2 characteristics of state and behaviors. The state is nothing but an identity of the object(data) and behavior describes the function(method) of the object.
Example:
Object: Mobile
State: Name, Model No, Color
Behavior: Calling, messaging, switch on, switch off, take photos, etc.
Let's understand this with an example. Here class name is Mobile and it has attributes or states as mobilename, modelNumber, and color. In java programming, we call these attributes as variables and behaviors as methods.
The methods are call(), message(), switchOn() and switchOff().
