Java, defining a method -

i'm new programming....not sure how add / define methods lower half of program work.

import static java.lang.system.out; import java.text.*; import java.util.*; import java.lang.*;  public class dates  {     // --- add methods here make program work --- //  // attempted solution nameformat method!!!!!! 

//keep getting "cannot find symbol - variable nameformat //or cannot convert string int error if give return value //have scoured internet examples , can't figure out.

    public static int nameformat(int year, int month, int day)      {         simpledateformat nameformat = new simpledateformat("yyyy, mm, dd");         date date = nameformat.parse("2014, 10, 4");         simpledateformat sdfdestination = new simpledateformat("mmmmm dd, yyyy");          return nameformat < not sure put here;     }      public static void printdate(int year, int month, int day) {         out.println(nameformat(year, month, day));         out.println(slashformat(year, month, day));         out.println(dashformat(year, month, day));         out.println();     }      public static void main(string[] args) {         printdate(2014, 10, 4);         printdate(2015, 1, 1);         printdate(2013, 12, 31);     } } 

look here understanding how method works: http://mathbits.com/mathbits/java/methods/lesson1.htm

generally, how method defined:

  public static int functionname(int a, int b ...) {  // put want method do.  return (something);        }
