Features of Java

1. Platform Independent

– Java code ko ek baar likha ja sakta hai aur phir use different platforms par bina kisi badlav ke chalaya ja sakta hai. Iska mtlb hai ki ek bar likha gaya Java code Windows, Mac, ya Linux par chalaya ja sakta hai bina kisi pareshani ke.

2. Object-Oriented 
– Java ek object-oriented programming language hai, iska mtlb hai ki har cheez ko objects ke roop mein represent kiya ja sakta hai. Yeh approach code ko modular aur flexible banata hai.

3. Simple and Easy to Learn

 kliye bhi aasan hota hai. Isme complex features ki kami hoti hai, jo programming ko samajhne mein madad karte hain.

4. Multi-threaded 
– Java ek multi-threaded programming language hai, jiska mtlb hai ki ek sath kai tasks ko chalaya ja sakta hai. Yeh performance ko improve karta hai aur concurrent programming ko asaan banata hai.

5. Platform Security– Java mein built-in security features hote hain jo unauthorized access se bachate hain. Java Virtual Machine (JVM) security ke liye responsible hota hai.

6. Rich Standard Library– Java ka ek bada benefit hai uski rich standard library jisme pre-built classes aur functions included hote hain, jo developers ko kaam karne mein madad karte hain.

7. Dynamic Memory Allocation 
– Java automatic memory management karta hai, iska mtlb hai ki developers ko manually memory allocate aur deallocate karne ki zarurat nahi hoti. Yeh garbage collection ke through automatically hota hai.

8. Exception Handling
– Java mein robust exception handling mechanism hai, jo runtime errors ke sambandh mein handle karne mein madad karta hai aur code ko stable banata hai.

9. Distributed Computing 
– Java distributed computing ko support karta hai, jisse ki applications ko alag-alag systems par spread kiya ja sake.

10. Community Support 
– Java ka ek bada samarthan samuday hai jisme developers aur experts ek dusre ki madad karte hain. Yeh ek vibrant aur active programming community ka part hai.

What Is OOPS

“Object-Oriented” ka matlab hota hai ki programming ka tareeka jisme hum apne code ko objects ke form mein likhte hain. Ab, yeh ‘object’ kya hota hai? Samjho ise ek virtual ‘thing’ ya ‘concept’, jise hum code mein represent karte hain. Har ek object apne aap mein ek puri duniya hoti hai jisme uski khud ki properties (gun) aur behaviors (kriyayein) hoti hain.

Let’s take an example: Imagine a car. Car ek object hai jisme properties ho sakti hain jaise color, model, aur speed. Iske alawa, car ke kuch behaviors bhi hote hain jaise start, stop, aur accelerate karna.

Ab, jab hum code likhte hain object-oriented approach mein, toh hum car ko ek class mein define karte hain. Class ek blueprint hota hai jisme hum define karte hain ki ek car ke kaise properties aur behaviors honge. Aur jab hum ek class ko use karte hain, tab usse create hua object real-world mein represent karta hai.

Object-Oriented programming ka fayda yeh hai ki code ko modular banata hai. Har object apne aap mein ek unit hai jiska apna kaam hota hai, aur jab hum in objects ko combine karte hain, toh hum complex systems ko asaan tareeke se design aur maintain kar sakte hain. Isse code reusability bhi badhti hai, kyunki ek bar likha gaya code dusre projects mein bhi use kiya ja sakta hai.

Toh, Object-Oriented programming ek tareeka hai jisse hum apne code ko organized, flexible, aur reusable banate hain, jisse programming ek creative aur effective process ban jaata hai.
