653: Mainline

Once you have imported an entire package, or just one compilation unit, from a package, you can refer by name to the single public class in each compilation unit. For example, once you have loaded the onto.java.entertainment package, you can refer to the various public classes found in the compilation units:

import onto.java.entertainment.*;
import java.io.*;
import java.util.*;
public class Demonstrate {
 public static void main(String argv[]) {
  Vector mainVector;
  mainVector = Auxiliaries.readMovieFile("input.data");         
  for (Iterator i = mainVector.iterator(); i.hasNext();) {
   System.out.println(((Movie)(i.next())).rating());            
  }  
 } 
}
