Java is a high-level, object-oriented, and portable programming language. It is characterized by having a clear and readable syntax, making it easy to learn.

It is widely used in various areas, such as enterprise application development, mobile applications, and games.

Java runs on the Java Virtual Machine (JVM), which makes it platform-independent and allows Java programs to be executed on different operating systems without modifications.

What is Java?

Java is a high-level, object-oriented programming (OOP) language that was developed by Sun Microsystems (now owned by Oracle Corporation) in the 1990s. It is one of the most popular and widely used languages in the field of programming.

Java is known for its portability, which means that Java applications can run on different platforms and operating systems without the need for modifying the source code. This is achieved through the use of the Java Virtual Machine (JVM), which interprets and executes Java code at runtime.

One of the main features of Java is its focus on object-oriented programming (OOP). It is based on the concept of objects, which are instances of classes that encapsulate related data and behaviors. OOP promotes code reusability, modularity, and efficient program organization.

Java also has a wide standard library that provides a variety of pre-defined classes and methods for performing common tasks such as string manipulation, input/output operations, database access, networking, and many other functionalities.

In addition to its emphasis on OOP and its standard library, Java is also used in web application development through technologies such as JavaServer Pages (JSP) and Java Servlets, as well as in enterprise application development using the Java EE (Enterprise Edition) framework.

Currently, the most recent Long-Term Support (LTS) version is Java 17, and in 2023, Java 20, which is considered a milestone, will be released. Java 8 is the most popular version, as it introduced Lambda Expressions that enhance functional programming in Java.

  • The main() method
    When we execute a Java program, the JVM (Java Virtual Machine) will look for the main() method to start a Java process for our program and then the JVM calls the underlying system in which is running to allocate memory and CPU time, an so on, until the program terminates.
  • Java APIs
    Java’s API offers a variety of prewritten tools, such as classes, interfaces, and packages, providing essential functionality for developers. It includes Core, SE, EE, and ME APIs, as well as the Collection, Stream, I/O, Concurrency, JDBC, and JPA APIs.
