Introduction to JAVA |Core Java| Programming

In this video, I have explained about "Basics of java".

Java is a class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.

Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle) and released in 1996 as a core component of Sun Microsystems' Java platform.

There are three platforms of the Java programming language:

1) Java Standard Edition (Java SE)
2) Java Enterprise Edition (Java EE)
3) Java Micro Edition (Java ME)

⭐Java SE
When most people think of the Java programming language, they think of the Java SE API. Java SE's API provides the core functionality of the Java programming language. It defines everything from the basic types and objects of the Java programming language to high-level classes that are used for networking, security, database access, graphical user interface (GUI) development, and XML parsing.

In addition to the core API, the Java SE platform consists of a virtual machine, development tools, deployment technologies, and other class libraries and toolkits commonly used in Java technology applications.

⭐Java EE
The Java EE platform is built on top of the Java SE platform. The Java EE platform provides an API and runtime environment for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.

⭐Java ME
The Java ME platform provides an API and a small-footprint virtual machine for running Java programming language applications on small devices, like mobile phones. The API is a subset of the Java SE API, along with special class libraries useful for small device application development. Java ME applications are often clients of Java EE platform services.

Java Advantages
1) Simple
2) Object-Oriented
3) Platform-Independent
4) Distributed
5) Secure
6) Robust

Java Disadvantages
UI (Look and Feel): The default look and feel of GUI applications written in Java using the Swing toolkit are very different from native applications.

Performance: SIgnificantly slower and more memory-consuming than natively compiled languages such as C or C++

Single-paradigm language: The addition of static imports in Java 5.0 the procedural paradigm is better accommodated than in earlier versions of Java.
