What is Java?
Java is a high-level, class-based, object-oriented computer language that is meant to have as few application variables as possible. It is a general-purpose computer language designed to let creators “write once, run anywhere” (WORA).
This implies that a Java code can run on all systems that accept Java without having to be recompiled. Java programs are often turned into bytecode, which could run on any Java virtual machine (JVM), no matter how the computer is made. Java’s style is close to that of C and C++, but it doesn’t have as multiple low-level tools as either of them.
How is Java used in web development?
Java can be used for multiple purposes when it comes to web dev; some of which include:
1. Server-Side Web apps
Java is a common computer language for creating web apps that run on the server. JavaServer Faces (JSF), Spring MVC, and Java Servlets are examples of Java-based web platforms that can be utilized to make powerful web apps. These tools make it simple to manage HTTP requests, control accounts, connect to databases, and create interactive web pages.
2. Web Services
Java makes it easier to make and use web services by giving us tools like the Java API for RESTful Web Services (JAX-RS) and the Java API for XML Web Services (JAX-WS). With these tools, developers can make and use web services, which let different systems talk to each other over the internet.
3. Java Applets
Although they are less widespread nowadays, Java applets were formerly frequently utilized for providing interactive functionality to web sites. Java applets are short Java applications that may be placed in HTML pages and executed through a web browser. They were put to use in activities such as animations, interactive forms, and games. However, because of security concerns and the emergence of alternative web technologies such as JavaScript, Java applets have become less common.
What Special Features of Java Are Useful In Web Development?
Java has numerous unique characteristics that are very beneficial in web development. Here are some of the highlights:
1. Durability and Dependability
Java’s strong typing enhances the durability and dependability of web applications, automated memory management (garbage collection), and exception-handling capabilities. These capabilities assist developers in writing more reliable and error-free code, lowering the likelihood of crashes and memory leaks. Exception handling enables graceful error recovery and gives a disciplined strategy for managing runtime exceptions, boosting web applications’ overall stability.
2. Enterprise Abilities
Because of Java’s enterprise capabilities, it is well-suited for developing scalable and enterprise-grade online applications. Java Enterprise Edition (Java EE, formerly Jakarta EE) technologies offer standards and APIs for creating distributed, transactional, and secure applications. Java EE provides capabilities like JavaServer Faces (JSF), Java Persistence API (JPA), Java Message Service (JMS), and Java Transaction API (JTA) that help developers create robust, high-performance online applications.
3. Large Ecosystem
Java has a large ecosystem of third-party libraries, frameworks, and tools that help with web development. These tools offer functionality and make basic web development jobs easier, such as handling dependency injection, managing database transactions, implementing security measures, and creating user interfaces. Spring, Hibernate, Apache Struts, and JavaServer Faces (JSF) are popular Java frameworks for online development.
