Learn JAVA programming language

Java is a high-level, object-oriented, cross-platform programming language widely used in the development of enterprise software, mobile applications, embedded systems and backend solutions for a wide range of industries. Noted for its portability, robustness and its focus on writing code once to run on multiple platforms, Java has become one of the most popular and widely used languages in the world of software development. Java is the back-end programming language most widely used by large corporations. Key aspects of Java:

1. Portability and Platform Independence: Code written in Java is compiled into bytecode, which runs on a Java Virtual Machine (JVM), allowing code portability to different operating systems without recompiling.
2. Object-oriented: Java is an object-oriented language, which means that everything in Java is an object. It is based on concepts such as classes, inheritance, encapsulation and polymorphism.
3. Security and Robustness: Incorporates security features in its design, with strict access control and a memory management system that prevents memory errors and resource leaks.
4. Java Standard Edition (JSE): Java has an extensive standard library that provides classes and methods to perform a variety of tasks, from basic operations to file manipulation, networking, data processing, among others.
5. Scalability and Performance: Java is scalable and adapts well to high load environments, offering good performance in large-scale applications.
6. Versatility and Popularity: It is used in a wide range of applications, from embedded systems and mobile devices to enterprise applications and web servers.
7. Extensive Ecosystem: It has an extensive ecosystem of frameworks, tools and libraries, such as Spring, Hibernate, Maven, among others, that extend its functionality and simplify development.

Java has established itself as one of the pillars of software development due to its versatility, portability, security and robustness. It is especially suited for environments where reliability, scalability and portability are key requirements, such as in the development of business-critical applications and large-scale distributed systems.

Springboot

Spring Boot is a Java-based application development framework that simplifies and streamlines the creation of enterprise applications. Built on the Spring Framework ecosystem, Spring Boot provides a convention-over-configuration approach that enables developers to quickly launch Java projects with minimal configurations. Spring Boot features and highlights:

1. Automatic Configuration: Offers automatic default configurations, eliminating the need for extensive manual configuration. Uses conventions and intelligent auto-configuration to quickly launch an application without requiring a considerable amount of configuration code.
2. Embedded Servers: It comes with embedded servers such as Tomcat, Jetty or Undertow, which facilitates the execution and testing of applications without the need to configure external servers.
3. Starter Dependencies: Provides preconfigured “starter” dependencies for different technologies and functionalities, making it easy to include specific functionalities in an application by simply adding dependencies.
4. Microservices-based development: It is especially suited for microservices development, allowing developers to create distributed and modular systems in a simple way.
5. Dependency Management: Use Maven or Gradle for dependency management, simplifying library and update management.
6. Acting as a Spring Framework Inversion of Control (IoC) Container: Inherits and builds on the capabilities of the Spring Framework, providing IoC and dependency management functionality.
7. Monitoring and Diagnostics: Provides integrated monitoring and diagnostic tools that facilitate real-time management and supervision of applications.

Spring Boot has become a popular choice for agile development of enterprise Java applications due to its simplified approach, its ability to reduce the amount of configuration code, and its integration with the broader Spring Framework ecosystem. It is especially useful in projects looking for rapid deployment, best practice tracking and microservices-based development. In the Ubiqum course Full Stack web development with Java the following programming languages are included: For the front-end. HTML, CSS, JavaScript and REACT For the back-end. Java and springboot.
