What is Java ?

  • Java is a programming language. Java was developed by Sun Microsystem and released in 1995Java developed by Sun Microsystems of USA in 1991.
  • Java is a high-  position, object-  acquainted programming language that was first released by Sun Microsystems( now  possessed by Oracle Corporation) in 1995. It is designed to be platform-independent, meaning that Java code can be run on any platform that has a Java Virtual Machine (JVM) installed.
  • Java is widely used for developing various types of applications, including web applications, desktop applications, mobile applications, games, and more. It is known for its simplicity, readability, and maintainability, making it a popular choice for developers.
  • Java has a large standard library that provides many pre-built functions and tools that can be used to simplify and speed up development. It also has a strong community of developers and users, who contribute to the development of libraries, frameworks, and other tools that can be used with Java.
It is used for :-   
  • Mobile applications
  • Games
  • Database connection
  • Web servers and application servers
  • Web applications
  • Desktop applications
  • Software development
Java syntax is similar to C/C++.
The Java code is first compiled into byte code.

Why Use Java ?

  1. Platform Independence: Java is a platform-independent language, which means that once you write a Java program, it can run on any platform that has a Java Virtual Machine (JVM) installed, including Windows, Linux, and macOS. This makes Java programs highly portable and easy to deploy on different platforms.
  2. Object-Oriented: Java is an object-oriented programming (OOP) language, which means that it allows you to build modular, reusable, and maintainable code. OOP allows you to encapsulate data and behavior into objects, making it easier to manage complexity and build more scalable applications.
  3. Rich Standard Library: Java has a large and comprehensive standard library that provides many pre-built functions and tools for common tasks, such as input/output, networking, and concurrency. This makes it easier and faster to build applications without having to write all the code from scratch.
  4. Memory Management: Java has an automatic memory management system that manages memory allocation and reallocation, which means that developers do not have to manually manage memory. This feature helps reduce the risk of memory leaks and other memory-related issues.
  5. Security: Java has a strong focus on security and provides several security features, such as a security manager, code signing, and access control mechanisms, which make it easier to build secure applications.

Java JVM Tutorial :

Java is a programming language and platform that allows developers to write software applications that can run on any platform that has a Java Virtual Machine (JVM) installed. The JVM is a software layer that provides an environment in which Java programs can execute.

There are many types of software that can be built using Java. Here are some of the most common types of Java software:

  1. Web Applications: Java is widely used for building web applications, such as e-commerce sites, social media platforms, and online banking portals. Java web application frameworks, such as Spring and Struts, provide a range of tools and libraries that make it easier to develop and deploy web applications.
  2. Desktop Applications: Java can also be used for building desktop applications, such as media players, image editors, and productivity tools. Java provides the Swing and JavaFX frameworks for building graphical user interfaces (GUIs) for desktop applications.
  3. Mobile Applications: Java is widely used for building mobile applications for Android devices. Android is based on the Java programming language, and developers can use the Android SDK and Android Studio to build and deploy mobile applications.
  4. Enterprise Applications: Java is also widely used for building enterprise applications, such as customer relationship management (CRM) systems, supply chain management systems, and enterprise resource planning (ERP) systems. Java enterprise application frameworks, such as Java EE and Spring, provide a range of tools and libraries for building enterprise applications.
  5. Games: Java is used for building games, especially casual games and mobile games. Java game development frameworks, such as jMonkeyEngine and LibGDX, provide a range of tools and libraries for building 2D and 3D games.
