Java coding ek programming language hai jo object-oriented programming ka use karti hai. Yeh language secure, reliable, aur portable hai, isliye widely use ki jaati hai. Java ko typically web applications, mobile applications (specially Android), enterprise applications, aur desktop applications develop karne ke liye use kiya jata hai.
### Java ke Features:
1. **Platform Independent:** Java ka code ek baar likha jata hai aur kahin bhi chal sakta hai (Write Once, Run Anywhere).
2. **Object-Oriented:** Java object-oriented programming principles ko follow karta hai jisme objects and classes ka use hota hai.
3. **Secure:** Java apni built-in security features ke liye jaana jata hai.
4. **Robust:** Java automatic garbage collection, exception handling, aur memory management ke features ke sath aata hai.
5. **Multithreaded:** Java multithreading ko support karta hai jisse multiple tasks simultaneously perform kiye ja sakte hain.
### Java Project Example:
Hum ek simple Java project banayenge jo user se input lega aur uska factorial calculate karega.
#### Step 1: Install Java
Sabse pehle aapko apne system me Java Development Kit (JDK) install karna hoga. Aap [Oracle's official site](https://www.oracle.com/java/technologies/javase-downloads.html) se latest JDK download kar sakte hain.
#### Step 2: Set Up Your Environment
Agar aapke system me IDE nahi hai to aap **Eclipse** ya **IntelliJ IDEA** download kar sakte hain jo Java development ke liye popular IDEs hain.
#### Step 3: Write the Code
Ab hum ek simple Java program likhenge jo user se input lega aur factorial calculate karega.
```java
import java.util.Scanner;
public class Factorial {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a number: ");
int number = scanner.nextInt();
int factorial = 1;
for (int i = 1; i <= number; i++) {
factorial *= i;
}
System.out.println("Factorial of " + number + " is: " + factorial);
}
}
```
#### Step 4: Compile and Run the Code
1. **Compile:** Command prompt/terminal me `javac Factorial.java` likh kar compile karein.
2. **Run:** `java Factorial` likh kar program run karein.
### Project Description:
- **Introduction:** Yeh project ek simple Java application hai jo user se input lega aur uska factorial calculate karega.
- **Usage:** User ko number input karna hai aur program us number ka factorial calculate karke output karega.
- **Script:**
- `import java.util.Scanner;` statement user input ke liye Scanner class ko import karta hai.
- `public class Factorial { ... }` statement ek public class define karta hai.
- `public static void main(String[] args) { ... }` method program ka entry point hota hai.
- `Scanner scanner = new Scanner(System.in);` statement user input lene ke liye Scanner object create karta hai.
- Loop aur conditional statements use karke factorial calculate kiya jata hai aur result print kiya jata hai.
