Java's main function denotes the entry point into the execution of your program.
public class PrimeNumberPrint {/*** @param args*/public static voidmain(String[] args) {// TODO Auto-generated method stubfor(int i =2; i < 10; i++) {System.out.println(i + " is prime is " + isPrime(i));}}public static booleanisPrime(int n) {int x = n;for(int i=2; i
function of static relay
'global static'?! There is no such thing.
The two are different, and independent from one another. A variable can be public, static, both public and static, or neither.
There is no difference between public static void and static public void

The main function is public because it means it needs to be called by any object. I had to check this myself but if you try to make the main function in Java private it will give you a run time error. It is static because it is indicating it is a class method and it does not need to be instantiated. Without the static keyword you would need to do something like this Main main = new Main();
'global static'?! There is no such thing.
A static function is a member function that is not associated with any instance of the class; it has no this pointer.
A public function is scoped to the class in which it is declared. If declared non-static, then it must be invoked against an instance of the class but if declared static then namespace resolution is required to access the function. A non-member function is not scoped to any class but may be scoped to a namespace. If no namespace is specified, then it is scoped to the (unnamed) global namespace. If scoped to any other namespace then namespace resolution is required to access the function.
The two are different, and independent from one another. A variable can be public, static, both public and static, or neither.
There is no difference between public static void and static public void
Use the "static" keyword to declare a static variable within a function like shown below. <?php function fun() { static $variable; static $another_variable = ''; } ?>
Scope of static variable is with in the file if it is static global. Scope of static variable is with in the function if variable is declared local to a function. But the life time is throughout the program
Always.
