Java Tutorial
What is Java
Java ek aisa programming language hai jise banane mein dhyan rakha gaya hai ki ye aasani se samajh me aaye aur versatile ho. Iska istemal har tarah ke software applications banane mein hota hai, jaise ki web applications, mobile apps, desktop applications, aur server-side applications.
**Key Characteristics of Java:**
1. Platform Independence (Platform Svarup Neutrality) :
Java ka ek mukhya feature hai ki iske programs ko ek bar likha ja sakta hai aur fir use kisi bhi device ya platform par chala sakte hai, jisme Java Virtual Machine (JVM) ho. JVM bytecode ko samajh sakta hai aur use native machine code mein convert karke execute karta hai.
2. Object-Oriented Programming (OOP) :
Java object-oriented programming ka bhi ek udaharan hai. Isme code ko objects mein organize kiya jata hai, jise fir aasani se reuse kiya ja sakta hai. Yeh approach code ko modular banata hai, jisse development aur maintenance mein asaan ho.
3. Robust and Secure (Mazboot aur Surakshit) :
Java robust hai, matlab ki isme error handling achha hai aur program ki stability ko maintain karta hai. Isme security features bhi shamil hain, jisse unauthorized access aur vulnerabilities se bachaya ja sakta hai.
4. Multi-Threading (Bahut Saare Threads) :
Java mein multi-threading ka support hai, jisse ek sath kai tasks execute kiye ja sakte hain. Isse performance improve hoti hai aur concurrent programming mein madad milti hai.
5. Rich Standard Library :
Java ke sath aata ek rich standard library, jisme kai tarah ke pre-built classes aur methods mojood hote hain. Ye developers ko time bachane mein madad karta hai, kyun ki wo bar bar naye functions likhne ki zarurat nahi hoti.
**Java Ecosystem:**
Java ek vast ecosystem ke sath aata hai, jisme development tools, frameworks, aur libraries shamil hain. Popular Java frameworks include Spring, Hibernate, aur Apache Struts, jo developers ko application development mein madad karte hain.
Overall, Java ek powerful, versatile, aur widespread programming language hai jo aaj kal bahut se different domains mein istemal hoti hai.
