How to Create Custom Class in Java?
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 MoreHow to Create and Setup Spring Boot Project in Eclipse IDE?
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 MoreHow to Create and Modify Properties File Form Java?
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 MoreHow to Create a Thread-Safe ConcurrentHashSet in Java?
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 MoreJava Program to Find the Mth element of the Array after K left rotations
In this problem, we will rotate the array by K left rotations and find the Mth element in the rotated array. The naïve approach to solve the problem is to rotate the array by K left rotation and take the element from the M – 1 index. The optimized approach is to find the final index value in such a way that the final index is the M – 1 index of the rotated array. Problem Statement We have given a nums[] array containing the positive integers. We have also given the positive integer K and M. We need ...
Read MoreJava Multicasting (Typecasting multiple times) Puzzle
Introduction Java Multicasting known as typecasting multiple times. It is the process of converting a value from one data type to another and it involves multiple typecasting conversions. It allows us to change the data type of a variable to perform operations that would not be possible otherwise. Let us discuss multicasting in Java. We will talk about numeric multicasting to convert between numeric data types. We will also discuss object multicasting to treat subclass objects as superclass objects. We will also provide simple programming examples to understand this topic easily. Numeric Multicasting in Java In this programming example we ...
Read MoreJava Method Parameters
Introduction We know that Java Method Parameters are variables used in method declarations to accept inputs and enable the methods to work with data that are dynamic. Let us discuss the Java Method Parameters and their use in making methods reusable and adaptable. We will discuss the importance of data input, code reusability, and flexibility. We will also explain about the pass−by−value and pass−by−reference by using Java Parameters with basic programming examples. By understanding the article, we hope our readers will understand the importance of the Java Method Parameters as it helps to create essential and maintainable Java programs. Definition ...
Read MoreJava JSON Processing (JSON-P) with Example
Introduction Java programs can operate with JSON data due to the strong Java JSON Processing (JSON-P) API. Web servers and clients frequently exchange data using the lightweight JSON data transfer standard. JSON-P offers the Object Model API and the Streaming API as its two primary methods for processing JSON data. Let us talk about these two strategies and use examples to show how they work and what they can do. We hope that our readers will learn about the Object Model API and Streaming API, together with Programming examples, by understanding this article's explanations on Java JSON Processing (JSON-P) with ...
Read MoreWhat\'s the best RESTful web framework to use with Java
Introduction Let us talk about what’s the best Java RESTful web framework to use with Java language. We know there are a lot of frameworks available but the “Spring Boot” is the best choice among other Java frameworks. Here we will talk about the usage of the RestTemplate and integration of various data formats including JSON, XML, and HTML using the Spring Boot framework. We will also discuss various approaches to handling HTTP requests. We will learn why Spring Boot is the ideal framework for creating RESTful web services in Java by understanding this article. Support of HTTP in ...
Read MoreDoes it make sense to choose JavaScript instead of Java for server-side programming and why
Introduction We know that over a period of time JavaScript has gained popularity for its versatility and it’s easy to use. Java remains a top choice for server-side programming due to its reliability, scalability, and large ecosystem. Let us discuss about why choosing Java as a server-side programming language over JavaScript is a better choice. We will talk about different approaches to explain the strengths of Java. Firstly, we will discuss the stability and robustness of Java by using Spring boot. Then we will explain the scalability and performance of Java. At last, we will explain the advantage of server-side ...
