Calling a method

the problem im sure is actually quite simple but i think im appraching it the wrong way.
whenever i compile and run this class it terminated straight away. ie. "Process exit" is displayed.
it creates the object i think cuz there are no erros in my film object code.

basically all i want to know is how do i get the readFilmDetails method to be displayed. Why does my program not ask the user to input the data.

many thanks

pete

class filmTest
{
      //properties
      private String filmName;
      private int filmRating;
      private double filmMinutes;
      private int age;

      public static void main(String[] args)
      {
            Film[] film = new Film [5];


      }

      public void readFilmDetails()
      {
            System.out.println("Film Name: ");
            filmName = uuInOut.ReadString();
            System.out.println("Enter film rating: ");
            filmRating = uuInOut.ReadInt();
            System.out.println("Enter film minutes");
            filmMinutes = uuInOut.ReadDouble();
      }

      public void readAge()
      {
            System.out.println("Enter Age: ");
            age = uuInOut.ReadInt();

      }

}

You don't call the method readFilmDetails.

When your program is first started it executes the main method, you should call readFilmDetails inside here.
eg.

public static void main(String[] args)
{
Film[] film = new Film [5];
readFilmDetails();
}

twobitadder

public static void main(String[] args)
{
Film[] film = new Film [5];
readFilmDetails();
}

should be

public static void main(String[] args)
{
Film[] film = new Film [5];
filmTest.readFilmDetails();
}

whenever i add in
readFilmDetails();
i get the following error msg.

filmTest.java:14: non-static method readFilmDetails() cannot be referenced from a static context
filmTest.readFilmDetails();

yes i did see that, no offence was intended,
however i didnt think that was the 'correct' way to do it. i tried it and saw it worked but thought it was a strange way to get it inputed. correct me if im wrong because im hardly experienced in java.

CEHJ

No it's customary. You can turn your method into a static one and then you *would* be able to call it with

filmTest.readFilmDetails();

but at the moment it's an instance method, not a class one, and therefore requires an instance of class fileTest to be created before it can be called
