In Java, a class is a fundamental component of object-oriented programming. It serves as a blueprint or template for defining the structure and behavior of objects. A class contains both data, represented by fields or variables, and behaviors, represented by methods or functions, which manipulate that data. In Java, a custom class is a user-defined class that allows you to create objects with specific properties and behaviors tailored to your application's requirements. It serves as a blueprint or template for creating objects of that class type. Custom classes encapsulate related data and operations into a single entity, promoting code organization, ... Read More
The Spring Boot framework incorporates all of Spring's capabilities and features because it is built upon the basis of Spring. Developers are drawn to it because of its effective production-ready environment, which frees them up to focus on the logic of the application rather than on setup and configuration. Microservices-based applications that are suitable for deployment in a production environment may be created quickly thanks to Spring Boot. Some of the key features of Spring Boot are − Auto-configuration − Spring Boot's standout feature is its auto-configuration capability. It analyzes the project's classpath and automatically configures the necessary beans ... Read More

Program in Text and XML Format? In Java, a project's properties file is made up of text-based key-value pairs that are commonly stored with the .properties extension. The key-value pair of contents are presented line by line, and they are often created using notepad, Wordpad, etc. Properties files serve as valuable repositories for storing critical and confidential data. In this article, we will explore the process of creating a properties file using a Java program. The Properties class in this (java.util.Properties) package offers multiple utility store methods that facilitate the storage of properties in either Text Format or XML ... Read More
In this article, we will learn how to create a TreeMap in reverse order in java. Firstly, we need to know about TreeMap. A TreeMap in Java is a class that implements the SortedMap interface, which extends the Map interface. It is a collection that stores key-value pairs and organizes them based on their natural order or a custom Comparator provided during its creation. This approach provides efficient performance for common operations such as adding, removing, and retrieving elements from the TreeMap. It has an average time complexity of O(log n), which ensures efficient execution. Syntax for Creating a TreeMap ... Read More
In this article, we will see what are the possibilities available to create thread-safe HashSet instances and see what will be equivalent to ConcurrentHashMap for HashSet. We will also look at the benefits and drawbacks of each approach. Before JDK8 we are not able to create a Thread Safe ConcurrentHashMap because java.util.concurrent package in JDK8 does not provide a class named ConcurrentHashSet, two new methods were added that are discussed below. ConcurrentHashMap is the Map implementation that allows us to modify the Map while iterating. The ConcurrentHashMap operations are thread-safe. ConcurrentHashMap doesn't allow null for keys and values. Ways to ... Read More
In this problem statement we have to move all the files in the folder with the name of creation and modification date directory with the help of Python. In this task we will use some predefined libraries of Python for smooth processing of relocating the files. Understanding the Problem As we have seen, managing the files as per the date or modification and creation time. So here in this article we will simplify this task by creating the Python script to move the files as per the creation and modification dates by giving the folder name as the modification or ...

The given problem statement is to relocate all the files from the subfolders to the main folder using Python. So we will use the OS and Shutil libraries of Python to do this task. Understanding the Logic for the Problem In this task, we are required to move all the files that exist in the subfolder in the main folder using Python programming language. So for doing this process we will specify the source folder path and destination or main folder path. And we will be using python’s os and shutil libraries for doing this task. So first we will ...

In the given problem statement we have to apply a motion_blur function for an image using the Python wand library. Sometimes we are needed to perform the blur operation on some images. So using the Python wand we can do this task easily and blur the image to any extent. What is Python Wand? The wand is a tool, which is used to convert the format of images. It can convert the image from one format to another. This library provides a wide range of functions to perform different kinds of operations of the image for manipulating them. To install ...
