Object-Oriented Programming has great advantages over other programming styles:

Cross- functionality and portability

Java offers higher cross-functionality and portability as programs written in one platform can run across desktops, mobiles, embedded systems.

Multi featured

Java is free, simple, object-oriented, distributed, supports multithreading, and offers multimedia and network support.

Stability

Java is a mature language, therefore more stable and predictable. The Java Class Library enables cross-platform development.

Wide application area

Being highly popular at enterprise, embedded and network level, Java has a large active user community and support available.

Platform independent

Unlike C and C++, Java programs are compiled independently of platform in bytecode language which allows the same program to run on any machine that has a JVM installed.

Powerful Development Tool

Java has powerful development tools like Eclipse SDK and NetBeans which have debugging capability and offer integrated development environment.

Diversity

Increasing language diversity, evidenced by compatibility of Java with Scala, Groovy, JRuby, and Clojure.

Compatibility

Relatively seamless forward compatibility from one version to the next.

Efficiency of Code

Using the property of inheritance, we can eliminate extra code and entend the ude of existing classes.

Data Security

The Principle of data hiding helps to build secure programs that can not be occupied by code in other parts of the program, so it helps for creating secure applications.

Easy for Creating Project

It is easy to partition the word in a project based on objects.

Easy Manageable

Software complexity can be easily managed

Java is easy to learn

Java was designed to be easy to use and is therefore much more easy to write, compile, debug, run and learn than other programming languages.

Java is object-oriented

This allows you to create modular maintainable applications and reusable code.

Java is platform-independent

One of the most significant advantages of Java is its ability to move easily from one system to another. The ability to run the same code on many different systems is crucial to www, and Java succeeds at this by being platform-independent at the source and almost binary levels.

Java is distributed

Java is designed to make distributed computing easy with the networking capability that is inherently integrated into it. Writing network programs in Java is like sending and receiving data to and from a file.

Java is secure

Java considers security as part of its design. The Java language, compiler, interpreter, and runtime environment were each developed with security in mind.

Java is robust

Robust means reliability. Java puts a lot of emphasis on early checking for possible errors, as Java compilers are able to detect many problems that would first show up during execution time in other languages.

Java is multithreaded

Multithreaded is the capability for a program to perform several tasks simultaneously within a program. In Java, multithreaded programming has been smoothly integrated into it, while in other languages, operating system-specific procedures have to be called in order to enable multithreading.

What are the benefits of using Java over C++?

Easy to Learn

Consider to C++, Java is easier to learn. Java takes less time to learn the core concepts and syntax is similar to C and C++.

No Pointers

Java does not offer to use pointers. Pointers are little confusing for most programmers and using pointers without proper knowledge about pointer is not good.

Platform Independent

Java focuses the philosophy "Write Once Run Anywhere", meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

Garbage Collector

JVM has garbage collector which take care of automatic memory management. It will prevent memory leakage in Java applications.

Just in Time Compiler

JVM uses JIT compiler to executes Java bytes codes faster. Before implementation of JIT compiler in JVM, execution of Java applications were too slow compared to C and C++ applications.

Concurrent

One can create multi-threaded applications using Java. Concurrency is one of the important and coolest feature of Java platform. Advantage of multi-threading is using same memory location.

Reflective

Reflection is the ability of a computer program to examine, introspect, and modify its own structure and behavior at runtime.

Exception Handing

C++ also supports exception handling, but we have to manually specify the rule to handle the exceptions. Exception handling in Java seems more better than C++. Java also has extra features like finally block and throws for exceptions.

Easy to Deploy

Creating packages in Java makes ease for deployment. And also has own archiver formats like .jar for application deployment.

Web Application

Java is one of the important language for web applications. J2EE uses to create robust Enterprise level web applications.

There are some disadvantages of Java over C++.

1. Slow startup.
2. No native code compilation.
3. Takes more memory for execution.
4. Slower compared to C++.
5. Performance of C++ is better than Java.
<
6. Need to install JVM for deployment platforms.
