Main Method in Java
What is the main method in java?
The main method is a special method in a
class from where java starts to execute the code.
Why do we need the main method?
When we write code we can write code in so many classes. How to java knows
from where it should start executing the code it knows it from the main
method. The main method is the starting point. if we remove the main method
from the class we can't run that class. Think of the main method as the main
door of the house if it is not opened we can't enter the home.
How to write the main method?
In IntelliJ we can use a shortcut we can simply type main and hit enter
or tab, and it will write the main method for us.
Note:
For now, write all of your java code in the main if we write it outside the
main it might not work. Later on, we will learn how to write code outside
of the main as well
Demo:
1)Create a main method.
2) Try deleting any components from the main method, and you will notice it does
not work
