Introduction Of Java Programming language
Hello friend 🤞
From Today We will Start Learning About the Most Popular Programming Language Java.
So let's Start
Java - Java is a Most Popular High-level Programming Language that is Designed to be Portable, Secure, and Easy to Use. It Was Developed By James Gosling at Sun Microsystems in 1995 and Has Since become One of the Most Widely Used Programming Languages in the World.
Java is an Object-Oriented Language, Meaning That it is Treats Data and Behavior as Self-Contained Units Called Objects. It also Has a "Write Once, Run Anywhere" Philosophy, Which Means That Java Code Can Run On Any Platform That Has a Java Virtual Machine (JVM) Installed, Without the need for recompilation.
A Simple Hello world Program in Java
public static void main(String args[]) {
System.out.println("Hello, world!");
}
}
OUTPUT -
Hello, world!
Features Of Java :
- Platform Independence
- Object-Oriented Programming
- Garbage Collection
- Exception Handling
- Multithreading
- Security
- Robustness
- Rich API
- Scalability
- Open source
Platform Independence: Java is Platform-Independent, Which Means That Java Code Can Run on Any Operating System or Platform Without Needing to be Recompiled.
Object-Oriented : Java is an Object-Oriented Language, Which Means That it Supports the Concepts of Classes, Objects, Encapsulation, Inheritance, and Polymorphism.
Garbage Collection: Java Has an Automatic Garbage Collector That Frees up Memory That is No Longer Being Used, Making Memory Management Easier for Developers.
Exception Handling: Java Provides Built-in Exception Handling Mechanisms That Allow Developers to Handle Errors and Exceptions in a Systematic way.
Multithreading: Java Supports Multithreading, Which Means That Multiple Threads Can Run Concurrently Within a Single Program, Allowing for Better Performance and Responsiveness.
Security: Java Provides a High Level of Security by Running Code inside a Sandbox Environment, Which Prevents Malicious Code from Accessing System Resources.
Robustness: Java is Designed to be Robust and Can Handle Errors and Exceptions in a Graceful Way, Which Makes it a Popular Choice for Enterprise-Level Applications.
Rich Api: Java Provides a Rich Set of Apis That Make It Easy for Developers to Write Code for a Variety of Applications, Including Desktop, Mobile, and Web-Based Applications.
Scalability: Java Is Scalable, Which Means That It Can Be Used for Small Applications as Well as Large-Scale Enterprise-Level Applications.
Open source: Java Is Open-Source, Which Means That the Source Code Is Freely Available and Can Be Modified and Distributed by Developers. This Has Led to a Large Community of Developers Contributing to the Language and Making It More Robust and Feature-Rich Over Time.
