numbers. Concordances are useful for analyzing documents to find word frequencies and associations that are not evident from reading the document directly. This program builds a concordance for a text file. The run here uses this particular text taken from Shakespeare s play Julius Caesar. The first part of the resulting concordance is shown on the right. This output results from obtaining a Set view of the concordance and then iterating through the set, printing one element per line. Each element is a Map.Entry object whose Key is the word from the text (in all uppercase letters) and whose Value is the listing of line numbers where the word was found. For example, the word man was found on lines 10, 15, 22, and 27. Line 10 is

The hash table is defined at line 2. It has type java.util.HashMap<String,String>, which means that both its key and value fields have type String. Its constructor at line 4 takes the name of the input file as its argument. It uses a java.util.Scanner object to read the file line by line. Each line is parsed by a java.util.StringTokenizer object named parser, defined at line 11. Note that the parser uses as

delimiters all of the 11 characters in the string ",.;:()-! '". Each parsed word is used as a key in the hash table. The corresponding value is the string of line numbers that is accumulated at lines 16 and 18. The write() method at line 29 uses a for-each loop to print the concordance to the specified file. At line 32, the map s entrySet() method returns a set of elements of type Map.Entry<String,String>. These are the key/value pairs that are stored in the hash table. Each key is a word from the input file and its entry is the list of the line numbers of the lines where that word appears in the text. Here is the test program:
1 2 3 4 5 6 7 8 9 10
public class TestConcordance public static final String public static final String public static final String
{ PATH = "B:\\DSWJ2\\src\\ch08\\ex09\\"; IN_FILE = "Shakespeare.txt"; OUT_FILE = "Shakespeare.out";
public static void main(String[] args) { Concordance c = new Concordance(PATH+IN_FILE); c.write(PATH+OUT_FILE); } }
The output from the program in Example 8.9 demonstrates a critical feature of hash tables: Their contents are not ordered. To obtain an alphabetized printout of the concordance, we would have to sort it. THE TreeMap CLASS The TreeMap class extends the AbstractMap class and implements the SortedMap interface. It is called a tree map because its backing structure is a binary search tree instead of a hash table.
