Java VS Python: Which one is the future?

Since the 1990s, Java with Python has been actively used in the software development scene. These years they both have been witnessed for huge popularity through such an interesting evolution and getting attention of large communities of dedicated supporters world wide. Much so, there has always been a long lasting comparison and rivalry about the best programming language title between Java and Python.

These kinds of constant competitions between programming languages are pretty much common in the software development world. They help to understand much better the ups and downs of every technology and predict based on the analysis regarding their future popularity. This is an important pre visual for novice developers who want to learn programming languages. 

Almost after 3 decades since their appearance in the market, Java & Python both are still among the most famous and popular programming languages globally. Let’s jump right up to reviewing them to see their advantages and disadvantages. Also try to finalize as if there is any winner between these two programming languages. 

What is Java?

Java is a general-purpose programming language that first appeared in 1995. Over time, it has slowly but surely become one of the most in-demand tools for software development. One of its major claims to fame is being the default language for Android app development, which has played a big role in making Android the most popular mobile operating system.
But Java isn't just for mobile apps. It's an object-oriented language that's popular among web developers and is highly efficient for Big Data and IoT applications.

Key Features of Java 
Java's popularity comes from its many advantages and features. Here are some key highlights:
Write Once, Run Anywhere: Java is platform-independent, meaning the compiled code can run on any device with a Java Virtual Machine (JVM) without needing to be recompiled. This makes Java highly versatile.
Performance: Java applications are generally faster than those written in many other languages. Java supports multithreading and has automatic memory management, allowing apps to use computer hardware more effectively compared to languages like Python.
Stability and Backward Compatibility: Java's strict syntax and static typing mean that errors must be fixed before the code can be compiled, resulting in more stable and error-free software compared to dynamically typed languages like Python.
Community and Resources: Java has a large, active community that contributes to a wide variety of libraries and frameworks. The community also offers extensive documentation, educational tips, FAQs, and other resources to help developers learn and troubleshoot.
Java's strong foundation and robust features make it a go-to choice for developers in various fields, from web development to big data and beyond.

Disadvantages of Java 
While Java has a lot of benefits, it's not without its flaws. Here are some downsides to keep in mind:
Verbose Code: Java is known for being "wordy." You often need to write long lines of code to accomplish tasks that might take fewer lines in other languages.
Complex Syntax: The syntax in Java can be pretty complex. You'll be using a lot of curly braces and semicolons, which can make the code harder to write and read.
Steep Learning Curve: Even though there's plenty of documentation and learning resources, Java can be tough to master. The verbosity and complex syntax contribute to its difficulty compared to languages like Python.
Memory Usage: Java apps can be memory-intensive. The garbage collection process isn't always efficient, so Java applications can end up using a lot of RAM.

What's Python All About? 
Python is a super popular programming language, much like Java. Since it first came out in 1991, it's been all about making code simple and easy to read. Python's become incredibly versatile, showing up everywhere from machine learning to image processing and multimedia apps.

Why Everyone Loves Python 
Python's a big hit with developers for a bunch of reasons:
Simple Syntax: Python's syntax is straightforward and almost like English. It's concise too, meaning you can get more done with less code.
Fast Development: Thanks to dynamic typing and its overall simplicity, Python lets you write software faster and with fewer lines of code compared to other languages.
Easy to Learn: Python has a gentle learning curve. It's beginner-friendly with its simple syntax, intuitive commands, and tons of learning resources.
Powerful Frameworks and Libraries: Python comes packed with powerful tools. Django and Flask are great for web development, while TensorFlow, Scikit-learn, and PyTorch are perfect for machine learning. Plus, there are loads of libraries for scientific computing and data analysis.

The Downsides of Python 
Of course, Python isn't perfect. Here are some of its drawbacks:
No Multithreading: Python doesn't support true multithreading, which means it can't fully leverage modern CPUs for maximum performance.
Limited for Native Mobile Apps: Unlike Java, Python isn't ideal for native mobile app development. While there are libraries like PyQt and Kivy that help, it's still not as straightforward as using Java.
Poor Database Connectivity: Python's database access isn't the best and often requires additional modules like MySQL Connector Python or PyMySQL. It can't really compete with the robust Database Connectivity API in Java's Standard Edition.
And that's the lowdown on Python – a fantastic language with a few quirks, but overall a great tool for developers.

What Are the Differences Between Java and Python? 
Both Python and Java have much in common as the most popular programming languages. However, their most characteristic features lie in their differences. Let’s take a look at the most prominent distinctions by matching Java vs. Python.

• Syntax and Coding Style: Python is all about readability and simplicity. Its syntax is easy to read and feels like human language. On the flip side, Java has stricter rules and relies heavily on punctuation. While Python uses indentation to define code blocks, Java uses semicolons and curly braces. This makes Python's syntax more straightforward and less cluttered than Java's.
• Coding Speed: Python lets you code faster because it's concise and dynamically typed, meaning you can get the job done with fewer lines of code. Java, being statically typed with more complex syntax, can slow down your coding speed. However, Java has a ton of libraries with pre-made solutions, which can make some tasks easier.
• App Performance and Stability: Java is both compiled and interpreted. Before a Java program runs, it goes through a compilation process that checks for errors. This often leads to better performance and stability since any issues are caught before execution. Python, on the other hand, is an interpreted language. Errors in Python code show up at runtime, which can cause your program to crash unexpectedly.
• Learning Curve: Python is known for its simplicity and is often recommended as the first programming language to learn. It's intuitive and easy to pick up. Java, while more complex than Python, is still easier to learn compared to older languages like C++. Many beginners start with Java despite its steeper learning curve because it provides a solid foundation in programming principles. Plus, there are plenty of courses, forums, and resources to help you learn either language.

Java and Python Code Examples 
Here are two illustrative examples of the code written in Python and Java. This is how both languages handle a basic task: printing a message to a user, also known as a “Hello World” program
1. Java: 
public class Thank {
 public static void main(String[] args) {
   System.out.println("Thanks for reading our blog.");
 }
}
2. Python: 
print("Thanks for reading our blog.")

Java vs. Python: Which is Better for the Future?
