Ⓜ️Main Method

What is a Method? (Interview Question)

A method defines an action that an object can perform. Think of it like a verb, just like objects can jump, sleep, etc.

Within a method's curly brackets is where you write the code for the action. This could be setting or retrieving variable values, performing calculations, printing outputs, etc.

When calling a method on an object, you use the dot notation (objectName.methodName). This tells the object to carry out what's defined in that method

🤖 The main() Method - Bringing Java Programs to Life!

The main() method is the heart and soul of a Java program ❤️. It is the entry point that kickstarts a Java application's execution.

📍 Where to Find main()

The main() method resides inside a class and must be declared as:

public static void main(String[] args) {

} 

🗝️ Understanding the Syntax

• public - main() is accessible from outside the class

• static - main() can be called without creating an instance of the class

• void - main() does not return anything

• String[] args - main() accepts a string array as parameter for command line arguments

▶️ Starting the Execution

The Java runtime calls the main() method to run your application. Code inside main() gets executed line by line.

📤 Passing Inputs to main()

The args parameter of main() can be used to pass inputs and configure the application at runtime.

🎉 Using main()

Typically, main() will:
