Python vs Java: which is best in 2019

Java: Java is a programming language that developers use to create applications on your computer. Chances are you've downloaded a program that required the Java runtime, and so you probably have it installed it on your system. Java also has a web plug-in that allows you to run these apps in your browser.

Python: Python is a general purpose programming language created in the late 1980s, and named after Monty Python, that's used by thousands of people to do things from testing microchips at Intel, to powering Instagram, to building video games with the PyGame library.

Python is a programming language that boasts a gentler learning curve, and a more intuitive coding style. Java is also another programming language, but with a distinct advantage compared to other programming languages. Programs made with Java can be run on any operating system that is able to run the Java virtual machine. This is because Java does not compile to native bytecode, like Python does; it compiles to a Java bytecode that can be read and executed by the virtual machine. The use of a virtual machine impairs the performance of Java programs due to the overhead incurred. Programs that are compiled to native code, like Python, can perform at its best because it can take advantage of optimizations. Although you can compile Java programs to native code, it does not perform as well.

A key feature in Python is the use of whitespace to indicate the beginning and end of blocks of code. Java, like most programming languages, use braces for the same functionality. To compare one to the other, an opening curly brace for Java is equal to an increasing indentation in Python. The closing curly brace for Java is the equivalent of a decreasing curly brace in Python.

Another difference between the two is how they deal with variables. Java is a strongly typed language, while Python is not. Basically, Java does not allow the data type of a variable to be changed, while Python does. Unlike most programming languages, Python allows you to assign a string to a variable that once held an integer value. This is not possible with Java, and you need to define a variable for each one with the correct type.

As a general comparison, we can say that Python is much simpler to use, and more compact than Java. It is generally easier to learn, and more forgiving when it comes to using shortcuts like reusing an old variable. You will also need fewer lines to write code in Python than in Java, partly due to the removal of the braces. As a side-effect, Python code is a bit easier to read and understand than Java.

Who should go for which Language?

Select Java, if you are a beginner and have never learned to program in a formal way. It is not just a question of understanding how the code works, what are classes, algorithm, flowcharts, libraries, functions, the concept of OOP and much more. Once you understand these details, you can learn any other language easily. On the other hand, if you have learned another structured or OOP language earlier, you can directly learn Python. Python has a short learning curve and has tons of modules that do any job for you. It is less verbose than Java with a great community which is always ready to help. As many Startups are using this language, it is known as Startup language. Getting fast prototypes developed and delivered a project faster is possible in Python, and it is an open source language, so you are not paying any licensing fees per system. Your learning process depends on the interest of your career.

Speed and Portability of Java vs. Python

The great advantage of Java is that it can be used to create platform-independent applications. Any computer or mobile device that is able to run the Java virtual machine can run a Java application, whereas to run Python programs you need a compiler that can turn Python code into code that your particular operating system can understand. Thanks to the popularity of Java for web applications and simple desktop programs, most devices already have the Java virtual machine installed, so a Java programmer can be confident that their application will be usable by almost all users. The disadvantage of running inside a virtual machine is that Java programs run more slowly than Python programs.

Overall Summary,

1. Java creates applications that work across various platforms, while Python does not.

2. Java programs tend to run slower compared to Python programs.

3. Java uses traditional braces to start and end blocks, while Python uses indentation.

4. Java employs static typing, while Python is dynamically typed.

5. Python is simpler and more compact compared to Java

Python vs. Java: Which is Easier to Use?

Most programmers agree that Python is an easier language for novice programmers to learn. You will progress faster if you are learning Python as a first language than Java. However, the popularity of Java means that learning this powerful language is essential if you want to develop apps for Android, for example. If you do need to learn Java, then help is at hand, jntu world java tutorials will walk you through everything you need to know.

Summary:

Java was a big step forward from the earlier complex language C++, and many people rightly fell in love with it. Python is an even bigger step in the same direction. It is a human-friendly language for expressing your ideas in a form that machines can turn into reality. With all that information, Java developers should give a try to learn Python. It’s a great scripting language for automating repetitive tasks. You can get a lot of freelance work and it also a well-embedded language for Java applications. It is a great alternative available to Java in many situations. Learning one OOP language is always good if you want to be a good programmer for the long run.
