• class : class keyword is used to declare classes in Java.

• public : It is an access specifier. Public means this function is visible to all.

• static : static is again a keyword used to make a function static. To execute a static function you do not have to create an Object of the class. The main() method here is called by JVM, without creating any object for class.

• void : It is the return type, meaning this function will not return anything.

• main : main() method is the most important method in a Java program. This is the method which is executed, hence all the logic must be inside the main() method. If a java class is not having a main() method, it causes compilation error.

• System.out.println : This is used to print anything on the console like printf in C language.
