What's New in Java 22? - Features and Benefits

Explore how businesses can use Java 22 and its features to enhance their software development projects.

After a long wait, Java 22 JDK was finally released in March 2024. So, why does Java keep updating its versions? It is because new updates solve the issues in the previous version and make programming development friendly. Many businesses looking for software development benefit from the latest version updates of a programing language like Java. These new latest Java features and enhancements have more accurate syntax and offer tools to solve complex issues.

Java version 22 helps integrate into native code and increases Java's adaptability with many applications. It helps Java developers to generate clean code and gel with the latest emerging and advanced technologies. It helps in staying aligned with modern software development technologies. Many small and medium businesses (SMBs) and enterprises outsource their software development requirements to avoid the hassle of resource management and lack of technical expertise. Through outsourcing, businesses hire Java developers or a team who can fulfill their project requirements.

Let's explore some Java 22 features. Our expert offers his opinion on how new features in Java 22 can be used in various businesses from different industries to streamline processes or improve customer experience and drive business growth.

Java 22: Features and its Practical Use Cases:

#1. Scoped Values:

These values hold information and avoid problems when different parts want to use the same information at the same time. These "scoped values" are assigned to individual tasks and every task has a copy of information it needs. 

  • Immutability and thread safety: Scooped values remain the same and can't be changed once they are put in the container, hence nothing can mess with them.
  • Automatic Lifecycle management: Developers don't have to worry about creating scoped values and then eliminating them when its not needed. It will automatically vanish when its purpose is fulfilled. It helps avoid cluttering issues.
  • Thread-safe sharing: Scooped values ensure that everything can be shared but not changed in any way. Its like these containers only show information in it, and it cant be trampled on.

Industry Use Case - Customer Relationship Management System (CRM)

In a CRM portal, when a customer rep accesses client information scoop values help organize the information in one place. This also prevents any data modification accidents and unauthorized access of information. There is no chance of memory leak as it cleans up after the session is over, helping enhance security and compliance.

#2. Steam gatherers:

It helps in managing vast data sets. Instead of checking everything manually, steam gatherers pick up the information that is most important and put it into one place. The best thing about steam gatherer is that it can manage parallel and sequential streams. The sequential stream can process tasks one by one while the parallel stream divides the task into many threads. The former is similar to doing one thing at a time and the latter is like multitasking or distributing work among a group to get it completed faster.

Java developers use it as tools for data processing, for filtering or changing data or to combine and summarizing data. These two actions are called intermediate operations and terminal operations. It helps them handle complex task and get the desired result. The feature also improves error handling capability, as it helps in managing exceptions that may occur during stream processing. This helps improve stability and reliability of Java applications.

Industry Use Case - Online Rental Platform

In online retail platform, this feature can help monitor customer feedback, gather reviews from various product pages. It can also help identify important information like comments and ratings from given feedback from customers. This can help businesses like SMBs and enterprises in the long run to map customer behaviour, preferences, trends. It will help in taking data-driven decisions and improve customer satisfaction.

#3. Structured concurrency:

It helps manage all tasks from start to finish, and ensures that no issues occur even when a task requires to be closed temporarily. It also helps with different tools for data management and for ensuring programs run smoothly.

Structured concurrency is a strategic approach that makes it easier to manage tasks. In Java Development kit 22, Java developers are relieved from having to deal with threads or difficult callbacks. Instead, they can create logical blogs of tasks and organize their code better to make it more simple and maintainable. 

Use case - E-commerce Platform

Take for example an e-commerce platform, like amazon where users can see and compare prices of various vendors for a particular object. For this, the Java developers have to create a system where multiple HTTP requests are sent to vendors APIs to check and use the current prices.  With structured concurrency, it can be done all at once with multiple vendors in parallel and handle all errors and keep the pricing up-to-date.

 

#4. Statements Before Super call:

In Java coding when a new class is created and it has attributes inherited from other class a special constructor class needs to be called from parent class. Java 22 has relaxed this condition for certain cases where developers can complete their task before calling the constructor.

This feature enables creating new object with customized properties to make it suitable for your upcoming task. It makes Java 22 more versatile and adaptable.

Industry Use case - Payroll Management System

A payroll management system needs validation checks and calculations. Before filling an employees general details this feature helps set specialized role for the employee like manager or intern and perform check to ensure salaries are according to performance and also verify if the candidate is eligible for bonus.

 

#5. Class-File API:

It allows developers to create, modify, or inspect files during run-time. It helps where modification is needed in frameworks or libraries. For Java developers Class-file API is like a tool-kit that shows internal structure of Java program files similar to having a blueprint.

It is like watching a lego from inside and identifying which pieces can help. This feature gives java programmers more flexibility and control over how the program behaves.

Industry Use Case - E-commerce

Class-file API can help add a plugin system to an e-commerce platform. It will enable developers to create customer plug-ins to add new features, customize UI or add third party services. Using Class-file API developers can package plugin files as JAR (Java Archive files). It will help CMS to identify and use the plugin without restarting.
