Java code can be written once and run on any platform that supports the Java Virtual Machine (JVM). This makes it easier to build applications that can run on a variety of devices and operating systems, without the need for significant code changes.
  • Performance
    Java’s performance has improved significantly over the years, thanks to its Just-In-Time (JIT) compiler and other optimizations. JIT compiles bytecode into native machine code at runtime, which results in faster execution times compared to interpreted languages. Additionally, Java’s garbage collection mechanism helps manage memory automatically, reducing the risk of memory leaks and other performance issues.
  • Security
    Java has built-in security features that help protect enterprise applications from malicious attacks. For instance, Java’s classloader mechanism ensures that only trusted code is executed, preventing unauthorized code from running. Additionally, Java’s sandbox model provides a secure environment for running untrusted code, making it easier to deploy applications securely.
  • Community Support
    Java has a large and active community of developers, which means that there are many resources available for enterprise application development. This includes tools, libraries, and frameworks that can help streamline the development process and improve code quality. Additionally, the Java community is known for its focus on backward compatibility, which means that applications built with older versions of Java can still run on newer versions without significant changes.

JavaFX can be used to build desktop applications, mobile apps, and even web applications using technologies such as WebView.
  • Jakarta EE (formerly Java EE)
    Jakarta EE is the new name for Java EE, following its transfer to the Eclipse Foundation. Jakarta EE provides the same set of specifications and technologies as Java EE, but with a community-driven, open-source approach. Jakarta EE includes technologies such as Servlets, JSPs, JPA, and CDI, among others.
Best practices for building robust and scalable enterprise applications using Java
  • Design for scalability
    Scalability is a critical consideration for enterprise applications, which must be able to handle high traffic and large amounts of data. To design for scalability, it’s important to use a layered architecture, separate concerns, and use caching and load balancing techniques.
  • Use design patterns
    Design patterns are reusable solutions to common software design problems. They can help improve the modularity, flexibility, and maintainability of your code. Examples of design patterns that are commonly used in Java enterprise applications include the DAO (Data Access Object) pattern, the Singleton pattern, and the Factory pattern.
  • Test early and often
    Testing is a critical part of the software development process, especially for enterprise applications that must be reliable and secure. To ensure the quality of your code, it’s important to test early and often, using automated testing tools such as JUnit and Mockito.
  • Use asynchronous programming
    Asynchronous programming allows your application to continue processing other tasks while waiting for a resource or event. This can significantly improve the scalability and responsiveness of your application, especially for I/O-bound tasks. Java provides several APIs for asynchronous programming, including CompletableFuture, RxJava, and Akka.
  • Monitor and tune performance
    To ensure that your application is performing optimally, it’s important to monitor its performance and tune it as needed. This includes measuring response times, identifying bottlenecks, and optimizing resource usage. Tools such as JProfiler, VisualVM, and YourKit can help with performance monitoring and tuning.
  • Follow coding standards and best practices
    To ensure the maintainability and readability of your code, it’s important to follow coding standards and best practices. This includes using meaningful variable names, writing comments, using consistent formatting, and following SOLID principles. Adopting a coding style guide, such as Google’s Java Style Guide or Oracle’s Code Conventions for the Java Programming Language, can help ensure consistency across your codebase.


Tips for optimizing performance and scalability
  • Use connection pooling
    Database connections can be a bottleneck for enterprise applications, especially when handling high traffic. Connection pooling allows you to reuse connections instead of creating a new connection for each request, which can significantly improve performance. Popular connection pooling libraries for Java include HikariCP and Apache Commons DBCP.
  • Optimize database queries
    Optimizing database queries is an important part of improving the performance and scalability of your application.
