• EXAMPLE

  Construct an instance of Tree from file, print its structure to STDOUT, and then write it back to file:

  import ardnew.Tree;
  
  public class BracketTest
  {
   public static void main(String[] args)
   {
     Tree<String> bracket = new Tree<String>();
  
     if (bracket.readFile("/Users/andrew/brackettest/in.dat"))
     {
       bracket.print();
       bracket.writeFile("/Users/andrew/brackettest/out.dat");
     }
   }
  }
  

  The print() routine looks liek:

                                   /-------[ node 31
   
                           /-------[ node 15
   
                           |       \-------[ node 30
   
                   /-------[ node 7
   
                   |       |       /-------[ node 29
   
                   |       \-------[ node 14
   
                   |               \-------[ node 28
   
           /-------[ node 3
   
           |       |               /-------[ node 27
   
           |       |       /-------[ node 13
   
           |       |       |       \-------[ node 26
   
           |       \-------[ node 6
   
           |               |       /-------[ node 25
   
           |               \-------[ node 12
   
           |                       \-------[ node 24
   
  -------[ node 1
  
         |                       /-------[ node 23
  
         |               /-------[ node 11
  
         |               |       \-------[ node 22
  
         |       /-------[ node 5
  
         |       |       |       /-------[ node 21
  
         |       |       \-------[ node 10
  
         |       |               \-------[ node 20
  
         \-------[ node 2
  
                 |               /-------[ node 19
  
                 |       /-------[ node 9
  
                 |       |       \-------[ node 18
  
                 \-------[ node 4
  
                         |       /-------[ node 17
  
                         \-------[ node 8
  
                                 \-------[ node 16
  

  An incomplete tree also looks like you'd expect
