Application development using programming language has become a challenge for a developer as the part of rapid application development concern. Due to fast-growing suites of development, such as plug and play kind of tools which are in demand.
About Java
Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform.
The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
Why is Java so popular?
One of the biggest reasons why Java is so popular is the platform independence. It is open source and Object Oriented. Programs can run on cross-platform; as long as the computer has a Java Runtime Environment (JRE) installed, a Java program can run on it. Java is fundamentally object-oriented.
About Python
Python was conceived in the late 1980s, and its implementation began in December 1989 by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands as a successor to the ABC language (inspired by SETL) capable of exception handling and interfacing with the Amoeba operating system.
Why is Python popular?
Python is an open-source and object-oriented programming language, its implementation and syntax. It pressures more on code readability. When compared to other programming languages like C++ and Java, it requires the programmer to develop lesser codes.
Why is Python so slow compared to Java?
Python as the language has several run-time implementations. CPython is usually interpreted and will be slower than native-code C#. It might be slower than Java, depending on the Java JIT compiler. Jython is interpreted in the JVM and has the same performance profile as Java.
Conclusion
Both Python and Java are prominent technologies. They are current trends of application development related. Python has its area of implementation for Data Science, IOT to make application lightweight and easy to handle. The scope of Java makes beginners to understand the approach towards Object-oriented Programming. Latest versions of Java follows certain approaches with regards to Python. As a developer, having knowledge of both Python and Java has an added advantage.
