Why should Main method in Java carry public static and void in its syntax always?

public static void main(String args[])

Every java programmer wondered to follow the syntax for main method as mentioned above. This is the reason behind the syntax. 

Why public - The access specifier of Main method is said to be public so that main method can be called outside of the class . This makes sure that JVM can easily access and execute the main method.

Why static - Main method is declared static so that JVM can call the main method with out creating instance for it. [While JVM tries to execute java program, it does not know how to create instance as there is no standard constructor defined for Main class].

Why void  - This is to make sure that Main method is not returning any values.

Cheers! Happy coding!

Shortcut Keys - saves your time

     Most of us know that "Print Scrn" button in our keyboard will help us to take snapshots of the  screen. It will be more useful in case of developers and people who are working from different places to share their outputs, issues and bugs they are facing. But the 'Print Scrn' button will provide you with the entire screen's snap. What if we want to have the specific screen alone leaving the rest of screens behind. In windows, we can make use of 'Alt' key along with 'Print Scrn' to take screen shot of our own specific window.


Good to know :- Alt+0169 will help you to type copyright symbol. Alt+0169 ==>> ©. We have to keep on pressing 'Alt' while entering 0169 to do this.
