James Gosling developed JAVA in 1995. It was earlier known as Oak. It was developed to handle portable devices and set up boxes. After the first version, there have been many changes in the language. Starting from developing a language for set-up boxes, now JAVA Programming has changed the web page interface from simple text to animation. It is a high-level object-oriented language. It derives the name JAVA from a coffee found on an island in Indonesia. Developers use JAVA in Web applications, mobile applications, enterprise applications, etc.

History Of Python

Python Programming Language was developed by Guido Van Rossum in 1989, in the Netherlands. Python was originally derived from a general-purpose programming language named, ABC programming language. The language came to use in 1991 and used very few codes to express the concept. The release version of Python had enough capability to provide core data types, and classes with inheritance and exception handling and function. The most popular coding language, Python, has completed 30 years of existence. This can be one reason to learn python. It is the inspiration behind the development of other coding languages like Cobra, Ruby, Swift, Boo, etc.

Some Key Differences Between Java & Python

1. Stability

JAVA is less prone to code crashes or issues than Python. It is because JAVA is more technically stable than Python. We can run the Python syntax in runtime while JAVA requires proper review and running before running. JAVA receives regular updates, and the frameworks and libraries are upgraded regularly. It keeps JAVA relatively stable compared to Python. Regular checks keep the language stable and less prone to lagging or crashing in heavy traffic.

2. Performance

performance diffrence between python and JAVA

On an average view, Python programs run much slower than the JAVA developed programs. On the other hand, Python requires much less code than JAVA for a specific function. The same outcome from Python has 3-5 fewer codes than JAVA. Also, JAVA is quick for application performance while in the software development lifecycle, Python is faster. Python is also quicker in debugging, code maintenance and bringing the code to market. The just-in-time compilation of JAVA ensures performance enhancement of JAVA during web application development.

3. Resources

Small and medium-sized projects prefer python over JAVA because of its cost-effective nature. JAVA requires a large budget, more time and a large team of programmers. Hence, the development process is slower in JAVA. Although, the final product will be of higher quality than python the development process will be slower and time-taking. Hence, JAVA is common as a language of the corporation and requires an all-around investment.

4. Demand Across the Market

JAVA is more in demand among developers. Python is common in the market due to its easy communication. Compared to JAVA, python is famous among small-sized businesses and corporations. The Github Octoverse shows JAVA as the second most demanded language, followed by python. But, according to the latest trends, the demand for JAVA has fallen drastically due to the advent of Kotlin. But, JAVA is still more in demand than python.

Advantages of Java Language

The advantages of the Java programming language are as follow,

1. Platform Independent

Java is a platform-independent programming language hence you can run the compiled Java programming code on all platforms. There is no need for any software for running Java code on other platforms, but the machine should have JVM (Java Virtual Machine). JVM is used to optimize and manage the program memory and it is also used to run Java programs on various operating systems & devices.

2. Object-oriented

Java is an object-oriented programming language, and this makes it easy to reuse objects in other programs. It uses various object-oriented concepts like class, inheritance, object, abstraction, polymorphism, and encapsulation. With object-oriented programming, you can make programs more organized and pre-planned.

3. Libraries

You get numerous open-source libraries in Java programming languages like Maven, Apache commons, Mockito, Guava, JHipster, etc. Java programming language has a huge community that makes Java the best and easy to learn programming language. The huge set of libraries are very helpful in making the development easy and fast.

4. Automatic Memory Management

Memory management is the process of allocation and de-allocation of objects. In Java, the programming language allocation of the memory is done automatically. The automatic memory management system used by the Java programming language is known as a garbage collector and this reduces memory footprint and lagging.

5. Multithreading

For maximizing the utilization of the CPU, the Java programming language allows you to run threads simultaneously. The process of running threads simultaneously is known as Multithreading. Multithreading is very useful for heavy programs & gaming and threads are independent so in case if there are any problems then the other threads do not get affected.

6. Simple

Java programming language has a simple syntax that is clean and easy to understand and this makes it an easy to learn programming language. The syntax of Java is based on C++ and it has removed various complicated features like operator overloading, explicit pointers, etc. All these features make Java a simple programming language.

7. Distributed Language for Easy Remote Collaboration

Java is developed as a distributed language and this means it has an integrated mechanism that allows Java programming language to share data and programs between different computers to get better efficiency and improved performance.

These were the important advantages of both programming languages. Now we will look the what are the major differences between Java vs python language.

Advantages of Python Language
