In September 2024, Oracle released Java 23, the latest version of its development platform. With new enhancements focused on productivity, performance, and security, Java 23 promises to be a key tool for developers and organizations. This article explores in detail the main features of Java 23, its benefits and its impact on modern software development.
Main new features of Java 23
Java 23 introduces several JDK Enhancement Proposals (JEPs) that improve the functionality and performance of the platform. These proposals cover areas ranging from security to code optimization, offering developers more control and efficiency in their projects.
Most important Java JEPs 23
Some of the most notable JEPs in this release include:
- JEP 445: “Unseal Classes”.. Facilita la creación de jerarquías de clases más flexibles y seguras, simplificando el diseño orientado a objetos.
- JEP 430: “String Templates”.. Introduce plantillas de cadenas, lo que permite una manipulación más segura y eficiente de los datos textuales.
- JEP 451: “Deprecate the Applet API for Removal”.. Marca el fin definitivo de los applets, que han quedado obsoletos frente a nuevas tecnologías web.
Productivity and Development Improvements
Efficiency and New Tools
Java 23 has been designed to improve the efficiency of development efficiency. Con la implementación de nuevas APIs y funcionalidades, los desarrolladores pueden escribir código más claro y fácil de mantener, lo que reduce errores y mejora el rendimiento general de las aplicaciones.
Simplification of the Code
One of the key features of Java 23 is the implementation of String Templateswhich allows developers to work with strings in a simpler and safer way. This type of enhancement not only speeds up the coding process, but also facilitates error detection, optimizing development time.
Java Management Service 9.0: Simplified Management
What is Java Management Service 9.0?
With Java 23 also comes Java Management Service (JMS) 9.0an advanced tool for the management of Java applications and environments. This service, native to Oracle Cloud Infrastructure (OCI), allows you to centrally manage both on-premises and cloud environments, providing a unified panel to monitor applications.
Advantages for Companies
JMS 9.0 improves visibility and control of Java environments, making it easier to make decisions about maintenance and upgrades. This is especially useful for companies that operate in hybrid or multi-cloud environmentsenvironments, as it allows for more efficient management and greater operational security.
Improved Performance with Graal JIT
Introduction to Graal JIT Compiler
The Graal JIT (Just-in-Time) Compiler is one of the most important innovations of Java 23. This compiler, written in Java, converts bytecode into optimized machine code in real time, allowing applications to run more efficiently.
Advantages of the Graal JIT Compiler
Unlike traditional compilers, Graal JIT offers significant improvements in peak performance. peak performanceThe software is designed to be used in a variety of applications, adapting the compilation according to the specific characteristics of the application in real time. This makes it an ideal tool for applications that require high performance, such as financial systems or high-demand applications.
Security and Scalability in Java 23
Security Improvements
Java 23 reinforces security measuresThe new security solution, introducing new optimizations that ensure that applications are more robust against vulnerabilities. This is essential to protect business applications and sensitive data from potential attacks.
Optimized Scalability
With the increasing adoption of microservices-based microservices and distributed systems, scalability is a crucial factor for any development platform. Java 23 includes optimizations that allow applications to scale more efficiently, making better use of system resources.
Benefits for Developers and Companies
Productivity and Performance
The new features of Java 23 enable developers to optimize their productivity through tools that simplify code and improve workflow. This results in faster and more efficient development, without compromising software quality.
Technological Innovation
Java 23 is designed to drive innovation in innovation in emerging technologies such as artificial intelligence and machine learning. The platform provides the necessary foundations to integrate these technologies into existing projects, facilitating the creation of advanced solutions.
Community and Collaboration in Java 23
The Role of OpenJDK and JCP
The development of Java 23 has been made possible thanks to the collaboration between Oracle and the global developer community through the OpenJDK and the Java Community Process (JCP). Estas entidades permiten que las nuevas versiones de Java se adapten a las necesidades reales de la industria, asegurando que la plataforma continúe evolucionando en la dirección correcta.
Events and Community Involvement
With the return of JavaOne in 2025Oracle continues to support the global Java community. This event will be a crucial forum for developers from around the world to share ideas and experiences on Java 23, contributing to the continued growth of the language.
Enterprise Support: Java SE Subscription
Oracle Java SE Subscription
Oracle offers a premium subscription, Java SE Subscriptionwhich provides world-class support to companies that use Java in their daily operations. This service includes access to advanced tools such as Oracle GraalVMwhich offers additional optimizations for mission-critical applications, as well as the Enterprise Performance Pack.
Oracle Code Assist
A new highlight is Oracle Code Assista code assistance tool based on artificial intelligence optimized for Java. This tool helps developers improve their efficiency by making it easier to write code faster and with fewer errors.
Future of Java with Java 23
Continuous Innovation
Java 23 marks an important step into the future of software development. With a focus on security, performance and scalability, this release is designed to be a key tool in creating innovative and robust solutions.
Adaptability to New Technologies
As technologies such as machine learning and artificial intelligence continue to evolve, Java 23 provides a solid foundation for integrating them into enterprise applications. Its ability to handle large volumes of data and complex processes makes it an ideal choice for large-scale projects.
Final thoughts
The release of Java 23 represents a significant advancement for the developer community and enterprises that rely on the Java platform. With improvements in productivity, security and performance, this release is ready to meet the challenges of modern development. In addition, new tools such as the Graal JIT Compiler y Java Management Service 9.0 reinforce Oracle’s commitment to innovation and the continued growth of the Java ecosystem. Java 23 not only improves developer efficiency, but also provides a robust and scalable platform to power the next generation of enterprise applications.
