Main Method In Java :

In Java, the main method is the entry point for a Java program. It is the method where the execution of the program begins. The main method has a specific signature and is required in every Java application.

Here is the basic syntax of the main method in Java:

java
public class MyClass { 
public static void main(String[] args) {
// Code to be executed
    } 
}

Let's break down the parts of the main method:

  • public: It is an access specifier that makes the method accessible from outside the class.
  • static: It is a keyword indicating that the method belongs to the class itself and not to any specific instance of the class.
  • void: It is the return type of the method, indicating that the main method does not return any value.
  • main: It is the name of the method. This name is recognized by the Java Virtual Machine (JVM) as the starting point of the program.
  • String[] args: It is the parameter of the main method. It is an array of strings that can be used to pass command-line arguments to the Java program. These arguments can be accessed within the method through the args parameter.

Inside the main method, you can write the code that you want the program to execute. This is where you define the logic of your program.

It's worth noting that the main method must be declared in a class, and only one main method can exist per class. Additionally, the main method must have the exact signature shown above for it to be recognized as the entry point of the program by the JVM.
