Flask, a lightweight web framework for Python, offers various tools and libraries for building dynamic web applications. When it comes to implementing user authentication in Flask, developers often turn to traditional database systems. However, there are cases where using a database might be unnecessary or overkill, such as small−scale applications or rapid prototyping. In such scenarios, implementing a Flask login system without a database can be a simple and efficient solution. By using memory data structures and Flask's session object, developers can create a basic login system that stores user information without the need for a database. In this article, ... Read More

In Java, the IntFunction interface is a functional interface that represents a function that accepts an integer type value as an argument and returns a result of any data type. Here, the functional interface means an interface that contains only a single abstract method and exhibits single functionality. Some examples of functional interfaces are Predicate, Runnable, and Comparable interfaces. The IntFunction interface is defined in the 'java.util.function' package. In this article, we are going to explore the IntFunction Interface and its built-in methods with the help of example programs. IntFunction Interface in Java The IntFunction Interface has a ...

TreeMap is a class of Java Collection Framework that implements NavigableMap Interface. It stores the elements of the map in a tree structure and provides an efficient alternative to store the key-value pairs in sorted order. Internally, TreeMap uses a red-black tree, which is a self-balancing binary search tree. A TreeMap must implement the Comparable Interface or a custom Comparator so that it can maintain the sorting order of its elements otherwise, we will encounter a java.lang.ClassCastException. This article aims to explain how TreeMap works internally in Java. Internal Working of TreeMap in Java To understand the internal ... Read More
