All executable programs need to contain a main method having teh following method signature which is called upon running teh compiled program:
public static void main( String[] args)
The main method is called by the jvm when your program is executed. The main method is a static method: public static void main(String[] args) {} A static method is method that can be run without instantiate the class (creating an object from it) The main method is a static method. No other static method could replace it's functionality. PS By static method do you mean static initialiser? I often use static initialisers instead of a main method, but in these cases you must still have a main method, albeit an empty one ie. public static void main(String[] args) {} Notice that the method has an empty body A main method must be used if you intend to accept parameters at run time from the jvm.
If you run an java file(as an .class or .jar file) there's always 1 method being called: The main(String[] args) method.The method is only called once.Example of an main method:public static void main(String args[]) throws IOException {LoggingBootstrap.bootstrap();gui = new GUI();}In this case it only bootstraps the logger and uses the constuctor method of GUI(the graphical user interface of the program)
The keyword public is an access specifier. A variable or a method that is declared public is publicly accessible to any member of the project. Any class or method can freely access other public methods and variables of another class.
In computer terminology, "running a program" means copying a sequence of instructions from storage into main memory and initiating the execution or interpretation of those instructions.
The same way you create a concrete method in a concrete class. When a class is abstract, it can contain abstract methods. That doesn't mean that all methods must be abstract. Hope this helps.
Call this method in your main method: public static double average(int n) { double total=0; double in3=0; Scanner input= new Scanner(System.in); int cntr=0; while(cntr<n) { in3=input.nextInt(); total+=in3; ++cntr; } return total/n; Good Luck!
I think you mean: why isn't there a function required in a servlet like the following? public static void main(String[] args) { } Because the main() method is what the Java VM 'boots up' into...it's the first thing the JVM executes. A servlet, however, is running inside a servlet container (e.g., Tomcat), which is running inside a JVM. *That* JVM gets started with a main() method, but unless you intend to run your servlet from the commandline, there's no explicit need for a main() method.
SpongeBob is the main characters name who is a sponge in the animated tv program SpongeBob SquarePants.
In programming, specifically in C and C++, the hashtag (#) is used to include files into the main program and to create macros.
branch mean branch direct to main office control but franchise is associate (dealer ship) method.
