Java remains a dominant language for building cross-platform applications, & enterprise software. It is widely used in web development, big data technologies, and cloud computing.
I just realized that Java is now being used for development across platforms. Java syntax comprises expressions, statements, statement blocks, and function blocks. It can be used to develop various applications, data center systems, scientific supercomputers, game consoles, desktop programs, and backend servers.
Everything cannot be coded with Java. It restricts game development, but it is suitable for scientific computing applications, and supercomputer simulations, and can be used to create games, particularly 2D games, leveraging libraries like jMonkeyEngine.
It is widely used for backend development, especially with frameworks like Spring, to create web services and APIs.
Reiterating What Goes in Favour, and What Needs an Effort
Java has crossed the barriers of the listed concepts and APIs. It is built upon objects, classes, and methods, core Object-oriented programming principles like inheritance, composition, encapsulation, abstraction, and polymorphism. Constructs like interfaces, abstract classes, inner classes (including local and nested), and anonymous inner classes are fundamental parts of the language.
It handles user input, utilizes the final keyword, and manages exceptions with try-catch-finally, throw, and throws. It supports user-defined exceptions, and access modifiers, and distinguishes between checked and unchecked exceptions. (1) String manipulation, (2) string literals, (3) String objects, (4) Enums are also integral parts of Java. Other features of Java like Servlet API, JSP, JDBC, JPA, and JSF vary according to standard, enterprise editions.
Should Java be Used, when Lightweight Languages are Available?
Java can run on any operating system – mobile, desktop, or web. It was one of the very old languages that originated just after Pascal, Cobol, Basic, C, and C++. It was fully developed and widely used at that time until lightweight alternatives evolved. Just because the basis was strong, and it had the probability to solve any problem that was handed to it, it still exists and is referred for enterprise app development.
It has (1) well-structured syntax, (2) automatic memory management, and (3) a large community of developers providing ample learning resources so that developers who have just started programming can code with confidence. It automatically manages memory, and deallocates unused variables (garbage collection), eliminating the need to manage memory manually.
C++ needs to be compiled separately for each platform, while Java compiles to bytecode executed by a Java Virtual Machine on any system, promoting modularity and code reuse, similar to C# and Python. The speed of C++ is faster than Java’s compilation and execution speed.
Also, C# is used with MSTS – Microsoft Runtime Environment, while Java comes with platform compatibility.
And, Go is simple and concurrent. Java is stable and backward compatible.
Using Java Application Development Services for Business Needs
Java’s cross-OS compatibility, libraries, and frameworks (Spring Framework, Hibernate, Vaadin, Grails, Play Framework, Apache Spark, Quarkus, JHipster, Vert.x), and ability to build high-performance systems due to its Just-In-Time compiler, optimizes code at runtime, allowing for efficient execution, combined with features like multithreading, efficient memory management (garbage collection), making it suitable for building scalable and performant applications when used with proper design practices.
Java can be used to code on desktop, web, android, and iOS platforms. We have discussed how it differs from other programming languages with similar features. A large community provides ample support, libraries (Apache Commons, Guava, Joda-Time,) and frameworks for diverse applications.
Java’s mature technology stack ensures application stability and minimizes downtime for mission-critical business systems. It is tagged along with Class Loaders, Security Manager, Strong Typing, Cryptography APIs, Secure Coding Practices, and Regular Updates.
Wrapping Up
Java application development services are a good starting point for dealing with problems that require complex mathematical calculations or string manipulation.
Serverless architecture, microservices, cloud-native development, reactive programming, artificial intelligence integration, improved security practices, and the adoption of modern frameworks like Spring Boot, all of which are increasingly being utilized by leading Java application development companies to build scalable, efficient, and adaptable applications.
Java often uses modular microservices, and reactive frameworks to build highly responsive applications. It is now evolving to integrate AI models and libraries into Java applications and glorify advanced analytics. It implements security measures throughout the development lifecycle.
C++ fares better in terms of garbage collection and memory management. I am saying this because Java does not eliminate the risk of memory leaks. When objects are no longer in use by the application, the JVM fails to recognize this and does not categorize it as garbage. So that memory remains occupied unnecessarily.
Java code can get really slow due to complex syntax, which languages like Python, Go, and Kotlin often address by offering faster execution speeds, more concise syntax, and improved garbage collection mechanisms, making them more efficient for certain applications.
Kotlin is good with coroutines. Scala and Futures are good with concurrent programming like Go. If the correct thing is placed at the correct place, at the right time, the chances of errors are reduced. All these are compatible with Java, so the resultant code is scalable and maintainable.
We can deduce that modern programming languages have been created as an improvement upon existing logic and programming practices. But Java can still be tagged along with it for a better experience.
