Head First java OO Movietester

[kieran haberstock]

Hi I am trying to figure how to get my code to run for the The movietestdrive in Head First java, but i the book isn't telling me enough. It would help a lot thank you. If it helps i have the code in two different classes.

  public class Movie {
	String title;
	String genre;
	int rating;
	
	void playIt () {
		System.out.println ("Playing the movie");
	}
}

public class MovieTestDrive {
		public static void main(String[] args) {
			Movie one = new Movie();
			one.title = "Gone with the Stock";
			one.genre = "Tragic";
			one.rating = -2;
			
			Movie two = new Movie();
			two.title = "Lost in Cubicle Space";
			two.genre = "Comedy";
			two.rating = 5;
			
			two.playIt();
			Movie three = new Movie();
			three.title = "Byte Club";
			three.genre = "Tragic but ultimatly uplifting";
			three.rating = 127;
		
		}
	}

You say you're trying to get your code to run, but it appears to me that it should run fine. What problems are you having with it? Are you getting errors? If so, post them, copied and pasted just as they appear at your end. If no errors, then describe how what is occurring does not meet your (or the book's) expectations.

I think they also missed a few opportunities with their film titles. A few suggestions for the authors:
"List in Space"
"Caddymap"
"Hash Bridges"
"Forrest Dump"
"Das Bit"
"Iterator"
"The Big Heap"

Hey...it's Sunday.

It’s probably still Saturday in Fiji. Surely the first one, now we are past Java1.4.2, is “List<T> in Space”

Execute it like this, assuming you have got your .java files already written in your “'java” directory, and they do not have package names:-

campbell@campbell-inspiron1110 ~]$ cd java
[campbell@campbell-inspiron1110 java]$ javac MovieTestDrive.java
[campbell@campbell-inspiron1110 java]$ java MovieTestDrive
Playing the Tragic movie . . . 

And you will get no output from the code you showed. You will need to add to the methods given. Change the playIt method to read like this

public void playIt()
{
   System.out.println("Playing the " + genre + " movie \u201c"
         + title + "\u201d, rating " + rating);
}

The \u201c and \u201d bits give you posh quote marks.
Change the main method by adding this sort of thing just before the first closing brace }

one.playIt();
two.playIt();
three.playIt)(;

Dang! Damn generics. Gets me every time...
