Java public static void main Method

What is the main method in Java?

It is the entry point of any Java application. Syntax:

public static void main(String[] args)

public class Hello {
    public static void main(String[] args) {
        System.out.println("Welcome to Java!");
    }
}

Why must the method be public? Because JVM must be able to access it from outside the class — otherwise it will give an error.
Why is it static? If it were not static, we would need to create an object of the class. But JVM should run the method without needing that.
What does void mean again? It means the method does not return anything. It just runs and ends.
Can I rename args? Yes, you can change args to any other name:
```
public static void main(String[] myInput) { ... }
```
But don’t change main, String[], or the order — JVM won’t recognize it.

Word	Type	Purpose
public	Access Modifier	Makes method accessible to JVM
static	Keyword	No object creation needed
void	Return Type	Nothing returned
main	Method Name	Predefined name used by JVM
String[]	Argument Type	Input arguments in form of String array
args	Argument Name	Reference name for input data

यह किसी भी Java प्रोग्राम की शुरुआत करने का पॉइंट होता है। Syntax:

public static void main(String[] args)

public class Hello {
    public static void main(String[] args) {
        System.out.println("Java में आपका स्वागत है!");
    }
}

method public क्यों होना चाहिए? क्योंकि JVM इसे बाहर से access करता है।
यह static क्यों है? ताकि इसे object बनाए बिना call किया जा सके।
void का क्या मतलब है? इसका मतलब method कोई value return नहीं करता।
args का नाम बदल सकते हैं? हाँ, इसे कुछ भी रख सकते हैं जैसे:
```
public static void main(String[] myInput) { ... }
```
लेकिन main, String[] या उनकी order को न बदलें।
