Will Python replace Java?

According to the IT programming trend, Java is currently more popular than other programming languages in terms of number of jobs, number of existing Java developers and overall usage statics in IT compared to Python. According to the latest 2018  usage statistics posted on a popular Technology Survey site, Java is being used by 3.0% websites as a server-side programming language, whereas only 0.2% of websites use Python. However, all the recent reports have highlighted that the usage and popularity of Python is growing drastically compared to Java where the Java usage is coming down year on year.

Both Java and Python are general purpose programming languages. While the former is a statically typed language wherein the programmers have to declare all variable names explicitly, the latter is looked upon as a dynamically typed language where developers are not required to declare variable names explicitly.
Java requires developers to write longer lines of code to accomplish common programming tasks. They also have to put in additional time and effort to organize, maintain and update the Java code base. On the other hand, syntax of Python enables developers to express concepts without writing longer lines of code. It further emphasizes on reusable and readable code generation. Thus, it becomes easier for programmers to maintain and update the code base.Both the languages have been updated on a regular basis. The programmers can use Java 8 to avail a number of new features including lambda expressions, a new date/time API and a new functional interface. They can further switch from version 7 to version 8 of the programming language without any hassle. But developers often find it daunting to choose between Python 2.x and Python 3.x. Both the versions are being maintained in parallel and hence switching from Python 2.x to Python 3.x is found to be challenging.
Java makes it easier for programmers to create portable cross-platform applications. These applications can run on any device on which Java virtual machine (JVM) is running. On the other hand, the developers have to use a Python compiler to convert the code written in Python into code understandable by the specific operating system. As JVM is installed on many devices, the developers can run Java applications on various devices without requiring any specialized tools and compilers.
The performance and speed of the two programming languages differ. Many programmers have proved that Java is faster than Python. While it cannot be used to accomplish CPU-intensive tasks, developers often have at their disposal, a number of options to enhance the execution speed of Python. They have to replace Python's default runtime with CPython, PyPy or Cython to increase the execution speed significantly. On the other hand, the performance of the Java application can be easily optimized without using any additional tools.
Along with being a popular web technology, Java is also used widely for developing apps for world's most popular mobile operating system, i.e., Android. The Android SDK includes a number of standard Java libraries. The developers can easily create Android apps by taking advantage of networking, data structure, graphics, and math libraries. They can even avail a number of tools and frameworks to speed up Android app development. But those into Python development know that it cannot be used for mobile app development directly and exclusively. The developers have to use additional frameworks and tools to use it for mobile app development. Many programmers prefer developing mobile apps with Java to save both time and effort.
So,i don't think so Python will replace java..

Dealing with Passwords in Java Applications: 5 Best Practices You Should Follow

 In modern Java applications—whether core Java applications or enterprise-level web applications—working with passwords is inevitable. Passwords are sensitive pieces of information, just like Social Security Numbers (SSNs), and if you’re handling real human data in systems such as online banking or healthcare portals, it’s critical to implement best practices for dealing with passwords securely. Below, I’ll share five essential best practices that I’ve learned and recommend for managing passwords, particularly when you are handling authentication and authorization. While these tips are a good starting point, be sure to tailor them to your application’s requirements and security policies. 1) Use SSL/TLS to Transfer Username and Password When users send passwords over the network, it is crucial to use SSL/TLS to encrypt the communication. This ensures that sensitive information is protected from eavesdroppers. Tools like LDAP and Active Directory are commonly used for storing usern...

Fail Fast and Fail Safe Iterator in Java

  The concepts of "fail-safe" and "fail-fast" are often discussed in the context of data structures and algorithms, particularly in Java programming. Let's understand what each concept means: Fail-Safe: Fail-safe refers to the property of a system or data structure that guarantees it will not fail, crash, or produce incorrect results, even when it encounters unexpected inputs or concurrent modifications. In the context of Java collections, a fail-safe iterator is an iterator that does not throw a ConcurrentModificationException if the collection is modified while it's being iterated. Instead, it operates on a copy of the original collection or uses some mechanism to handle concurrent modifications safely. For example, the Iterator returned by HashMap or ConcurrentHashMap in Java is fail-safe. If a collection is modified while an iterator is traversing it, the iterator will continue to operate on the original elements that were present when the iteration ...
