JAVA FRAMEWORKS
// Java Frameworks are platforms used for building software applications.
// They provide application-specific software and a standard way to build and deploy applications.
// Frameworks consist of various components like support programs, compilers, code libraries, and APIs.
// These components help in the selective modification of the software to meet specific requirements.
/*
* In Java, some popular frameworks are:
* 1. Spring Framework
* 2. Hibernate Framework
* 3. Struts Framework
* 4. JavaServer Faces Framework
* 5. Play Framework
*/
Java frameworks are used to build software applications. They consist of different components that provide standardized functionality that can be modified as per specific need. The Spring, Hibernate, Struts, JavaServer Faces, and Play frameworks are some popular frameworks in Java.
Understanding Java Frameworks
Java Frameworks provide a foundation for Java developers to create web applications using pre-existing codes. A Java Framework comprises of pre-defined classes and functions that process input and manage hardware devices linked to the system’s software.
Top Java Frameworks in the Software Industry
In the world of Java development, frameworks are essential tools used by developers to simplify and accelerate their work. Here are some of the most popular Java frameworks that are currently being used:
Spring Framework
Hibernate
Struts
JavaServer Faces (JSF)
Google Web Toolkit (GWT)
Apache Wicket
Play Framework
Introduction to the Spring Framework
The Spring Framework is a popular and versatile Java framework used to simplify the development of enterprise-grade applications. Its first production release was in 2004, and since then, it has gained immense popularity and is referred to as the “framework of frameworks.” Spring is an open-source, loosely coupled Java application framework.
Key Features and Uses
– Supports web application development and the creation of Enterprise Java Applications (JEE).
– Lightweight container and JDBC support for increased productivity and reduced errors. Allows backward compatibility and testability of code.
– Dependency Injection and Bean concepts make web development effortless.
Benefits
– The Spring framework provides a lightweight container that can be triggered without web/application server software.
– Offers excellent support for JDBC and supports backward compatibility and testability of code.
– Annotation-based and XML configurations can be extensively utilized with Spring.
Overall, Spring is used by numerous companies, including Amazon, eBay, Netflix, etc. for large-scale application development.
Hibernate Framework
Hibernate is a popular object-relational mapping tool for Java. It offers a framework for mapping a domain model to a relational DB. The main configuration file is HIBERNATE.CFG.XML, which contains database configuration and Java class mapping info. Software giants like IBM, Dell, and Oracle use Hibernate to develop persistent classes.
Hibernate offers several advantages:
- It follows object-oriented concepts, making communication with databases easier.
- It bridges the gap between objects and relational databases with minimal code alterations.
- It simplifies database operations on Java entities.
- It is free, open-source, and encourages code reusability.
- It helps achieve portability, productivity, and maintainability.
Play Framework
Play Framework is an open-source web application framework written in Scala, but it can also be used with other programming languages that compile to JVM bytecode like Java. It follows the Model View Controller (MVC) pattern and provides features such as hot code reloading, convention over configuration, and error messages in the browser. Play is suitable for web applications that need content creation and other Java and Scala applications.
Advantages of Play Framework include good support for non-blocking input/output for high-performance applications and flexibility and failure tolerance for results. It uses the Akka Toolkit and is designed to eliminate the issues of traditional Java web development such as slow software development cycles and excessive configurations.
Apache Struts: A Java MVC Framework for Web Applications
Apache Struts is a popular, free and open-source Java framework based on MVC architecture. It simplifies the creation of modern and attractive Java web applications. Struts prefers convention over configuration and offers a plugin architecture to support REST, AJAX, and JSON.
Major companies like Infosys, Accenture, and NextGen Technologies use Apache Struts. It provides two versions, Struts 1 and Struts2, which combines the webwork framework of OpenSymphony and Struts 1. Here are some benefits of Apache Struts:
– Simplifies the development of MVC-based Web Applications
– Extends the Java Servlet API
– Reduces application development time
– Makes application maintenance easier
– Offers central configuration through XML or property files
Get started with Apache Struts today and build excellent web applications with ease!
Dropwizard Framework
Dropwizard is a lightweight Java framework that supports features such as advanced configurations, logging, and application metrics. It can be used for fast-paced development and is ideal for developing operation-friendly applications, rapidly building Restful APIs, and creating Java microservices.
Dropwizard is advantageous over other frameworks due to its quick project bootstrap, support for various open-source and independent libraries, and ease of rapid prototyping.
//Sample code here
Google Web Toolkit (GWT)
Google Web Toolkit (GWT) is a Java-based framework developed by Google for creating elegant web applications. One of its notable features is its ability to convert Java code into customized JavaScript code based on the browser being used.
Popular Google products like AdSense, Google Wallet, and Blogger were built using GWT. It simplifies the usage of Google APIs, making it a developer-friendly framework. Additionally, GWT supports code reusability for common web development tasks and provides features like internationalization, UI abstraction, and cross-browser compatibility.
Java Server Faces (JSF)
Java Server Faces (JSF) is a Java framework designed for creating user interfaces for web applications. It follows MVC architecture and simplifies the UI construction for server-based apps by using reusable UI components. JSF is known for its stability and clear separation between application logic and representation, making it suitable for creating native applications.
Advantages of JSF:
* Provides various tools to create elegant UI.
* An integral part of Java EE.
* Enables extending existing backend Java code with a web interface without changing the base application.
Vaadin Framework
Vaadin is a popular open source Java framework that enables the creation of HTML5 web user interfaces in Java. Vaadin Flow, its lightweight Java framework, facilitates the communication between the browser and the server, making web development simple. Other advantages include the ability to bind data using MVC or MVP, use of Java and HTML for building views, WebSocket support, support for JVM languages such as Kotlin and Scala, and compatibility with the Spring framework.
Blade Framework
Blade is a Java 8-based web framework inspired by frameworks like Express, Flask, and Macaron. It aims to be self-contained, productive, elegant, intuitive, and fast. Blade has a restful routing interface that makes web APIs cleaner and easy to understand. It also has a built-in web server and template engine.
Blade is ideal for developing MVC-based web applications quickly. It supports plug-in extensions, web jar resources, and configuration in multiple files. Blade also provides protection against CSRF and XSS attacks.
Grails Framework Overview
Code:
Grails is a dynamic framework that works on the Java platform using the Groovy programming language. It is compatible with Java syntax and can integrate with Java technologies such as Spring, SiteMesh, Java EE containers, Hibernate, and Quartz.
Grails follows the “coding by convention” principle, which provides a standalone development environment with detailed documentation and hides configuration details.
Developers can create their own plugins and include Grails IDE support for various platforms, making it extremely developer-friendly.
Grails offers several advantages, such as easy intermixing of both Groovy and Java code, simple object mapping features, and flexible profiles.
