 Methods -- Style 1 
(does not receive arguments, does not return values)

Style 1:  Our first style of method will simply perform an independent task.  It will not receive any parameters and it will not return any values.  Such a method definition starts with the reserved words public static void, followed by the name of the method and a set of parentheses.  The word public indicates that there are no restrictions on the use of the method.  The word static means that all of the method's data will come from parameters or internal computations, with no reference to variables.  The word void is used to indicate that no value is returned.

NOTE: When using a method, it is customary to "comment" the method in some manner. Such documentation allows readers of the program, or other programmers also working on the program, to understand the method's purpose in the program. The commenting may be extensive, including detailed information about the method using the documentation comments (/**   */). In this course, we will not be adhering to the detailed documentation, but we will be listing simple, informative documentation.

//Demo Program for Methods

public class DisplayClass {
      public static void main (String[ ] args)  {

          System.out.println("Calling all methods!");
          asterisks( );     //invoking method (calling the method)
          System.out.println("Great job, method!");
          asterisks( );    //invoking method again
          System.out.println("We're outta here!");
      }
 
    //Method for asterisks
     public static void asterisks( ) {  // Method definition
    
          int count; 
          for(count = 1; count<=20; count++)
               System.out.print("*");

          System.out.println( );
     } 
}
