Hi Friend,
In public static void main(String[]args)
public-It indicates that the main() method can be called by any object.
static-It indicates that the main() method is a class method.
void- It indicates that the main() method has no return value.
(String args[])-It is used for receiving any arbitirary number of arguments and save it in the array.
In system.out.print()
System-The System class is a predefined class contains several useful class fields and methods. It manipulates various operating system related objects and provides access to the system.
out-System class has a field out of type PrintStream class that is connected to the console and allow to display something on console.
print()-It is a method in PrintStream class that displays the String which is passed to it.
Thanks
