613: Mainline

The catch blocks in the following version of the readMovieFile program, which you saw in a previous incarnation in Segment 600, announce where and why an exception is caught:

import java.io.*; 
import java.util.*; 
public class Auxiliaries { 
 public static Vector readMovieFile(String fileName) {              
  Vector v = new Vector();  
  try { 
   FileInputStream stream = new FileInputStream(fileName);  
   if (stream == null) {return null;} 
   InputStreamReader reader = new InputStreamReader(stream); 
   StreamTokenizer tokens = new StreamTokenizer(reader); 
   tokens.quoteChar((int) '"');  
   tokens.eolIsSignificant(true);  
   while (tokens.nextToken() != tokens.TT_EOF) { 
    String nameString = tokens.sval; 
    tokens.nextToken(); int x = (int) tokens.nval; 
    tokens.nextToken(); int y = (int) tokens.nval; 
    tokens.nextToken(); int z = (int) tokens.nval; 
    Movie m = (new Movie(x, y, z)); 
    m.title = nameString; 
    if (tokens.nextToken() == tokens.TT_EOL) {} 
    else {m.poster = tokens.sval; tokens.nextToken();} 
    v.addElement(m); 
   } 
   stream.close();  
  } 
  catch (FileNotFoundException e) {System.out.println(e);} 
  catch (IOException e) {System.out.println(e);} 
  return v; 
 } 
} 

This version of the Auxiliaries definition, which contains a definition of readMovieFile, serves up to Segment 45, where the FileInputStream mechanism is replaced by a more general mechanism that is better suited to handling files accessed via a network browser.
