Form of import -
import < enterprise >.   < package >.   *;  - > imports all classes in the package  

Ex:
import java.awt.   *;
import blue.cards.   *;
import white.words.   *;
 

NOTE
Off the CS1 home page we found documentation for the ``blue'' packages.  

Write an operator style method called iota which takes one positive integer as it's sole parameter and returns the array of integers containing 1,  2,  3,  ...   ,  n - where n is the parameter.  

Ex:
iota (5) - > [1] [2] [3] [4] [5]
iota (1) - > [1]
iota (9) - > [1] [2] [3] [4] [5] [6] [7] [8] [9]  

The Code:

static private int [] iota (int n)   {   / /declare an array of integers   int a [] = new int [n];   / /populate the array   for (int x = 0;  x < = n-1;  x + +)   {   a [x] = x + 1;   }   return a;   }

 

Write an operator style method which copies (i.e.   makes a copy of) an array of character strings.  

static private String [] copy (String [] s)   {   String c [] = new String [s.length];   for (int x = 0;  x < s.length;  x + +)   {   c [x] = s [x];   }   return c;   }

 

Define a class called Word which can be used to store words in terms of...

• The word
  
• The syllables of the word
  

Ex:
  [today] [to] 1

  [day] 2

Syllables  

Java code for the class definition  

public class Word   {   / /describe instance variables   private String word;   private String [] syllables;     / /constructors   / /this constructor will create a word by reading   / /info from the standard input stream and it will read:   / / * the word   / / * the # of syllables   / / * the syllables     today 2 to day   public Word ()   {   word = IO.readString ();   int numberSyllables = IO.read_int ();   syllables = new String [numberSyllables];   for (int x = 0;  x < = numberSyllables;  x + +)   {   syllables [x] = IO.readString ();   }   }     / /methods     / /compute the length of the word   / / (# of chars in the word)   public int length ()   {   return word.length ();   }     / /compute the # of syllables in the word   public int nrSyllables ()   {   return syllables.length;   }   / /end of word class definition}

 

Define a class which represents a named Dictionary.  

There will be 2 properties

• 1.   The Name (String)
  
• 2.   The Words (word [])
  

public class Dictionary   {   / /instance vars   private String name;   private Word [] words;     / /constructor # 1 - create an empty dictionary   public Dictionary (String theName)   {   name = theName;   words = new Word [0];   }     / /constructor # 2 - create a dictionary by reading elements   / / (word entries) from the standard input file   / /which begins with an integer indicating the # of word   / /entries     public Dictionary (String theName)   {   name = theName;   int nrWords = IO.read_int ();   words = new Word [nrWords];   for (int x = 0;  x < = nrWords;  x + +)   {   words [x] = new Word ();  / /using Word class   }   }

 

Note:
As things stand we can only use one of these two constructors.
