The line `public static void main(String[] args)` is the main method in Java, which serves as the entry point for a Java application. Here's a breakdown of each part:

1. 𝐩𝐮𝐛𝐥𝐢𝐜
- This is an access modifier. By marking the `main` method as `public`, you make it accessible from outside the class.
- The Java Virtual Machine (JVM) needs to call this method to start the application, so it must be `public`.

2. 𝐬𝐭𝐚𝐭𝐢𝐜
- The `static` keyword means that this method belongs to the class itself rather than to instances of the class.
- It allows the JVM to call `main` without needing to create an object of the class.

3. 𝐯𝐨𝐢𝐝
- This is the return type of the `main` method, indicating that it does not return any value.

4. 𝐦𝐚𝐢𝐧
- `main` is the name of the method, which is a standard in Java for the entry point method.
- The JVM specifically looks for `main` with this exact method signature to start program execution.

5. 𝐒𝐭𝐫𝐢𝐧𝐠[] 𝐚𝐫𝐠𝐬
- This parameter, an array of `String` objects, allows you to pass command-line arguments to the program.
- If the program is run with arguments, they are stored in this array. If no arguments are provided, the array is empty but not `null`.

public class MainClass {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}


𝐈𝐧 𝐭𝐡𝐢𝐬 𝐞𝐱𝐚𝐦𝐩𝐥𝐞:
- The `main` method prints "Hello, World!" to the console.
- `args` can hold any command-line arguments passed when running the program, like `java MainClass Hello`.

The correct syntax is `String[] args`, not `Strings[] args`. Using `Strings` would cause an error because `Strings` is not a standard type in Java.
