4 Threads Synchronized

[Mg Oo]

Please help me with the following quizz.
----------------------------------

A Java Program uses four threads. The first three threads each read a text file
and count the number of times that a given word is used in the text file.
The words which are to be counted are provided on a command line as shown when
the execution of the program is initiated : :

java countIt hello world me


The above line shows that countIt is the program being executed.
The first thread object counts the word 'hello, the second 'world' and the
third 'me'

Each of the thread objects communicates its findings to the fourth thread object which displays the results in a JTextArea as below : :

hello 4
world 9
me 3

Note that the words appear in alphabetical order.

---------------------------------------------------

The same functions for three threads ?
Synchronized four threads or synchronised after three threads job done ?
or Fourth threads Monitar execution of each thread ?

Thanks.
