Write a program CountWords in Java that reads text from a fi

Write a program CountWords in Java that reads text from a file and breaks it up into individual words. Insert the words into a tree set. At the end of the input file, print all words, followed by the size of the resulting set. This program determines how many unique words a text file has. If the file is not found, give the user a chance to select another file.

Solution

Code:

package chegg;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.StringTokenizer;
import java.util.TreeSet;

import javax.swing.text.html.HTMLDocument.Iterator;
public class Test {
public static void main(String args[]) throws IOException
{
  BufferedReader br = null;
     String sCurrentLine;
     TreeSet<String> ts = new TreeSet<String>();
     br = new BufferedReader(new FileReader(\"C:/Users/ansharm5/Desktop/chegg\"));
     while ((sCurrentLine = br.readLine()) != null) {
   StringTokenizer st = new StringTokenizer(sCurrentLine);
   while(st.hasMoreTokens())
   {
    ts.add(st.nextToken());
   }
  }
     System.out.println(\"Total no. of words: \"+ ts.size());
     java.util.Iterator<String> iterator = ts.iterator();
       
        while (iterator.hasNext()){
        System.out.println(iterator.next() + \" \");
        }
}

}
