Message:

Anyone seen a line of text???

Posted by Oz on December 10, 2000 at 3:49 PM

I have to read text from a file,
count the number of words in the text.
And in a method, count the number of vowels in the text and
the number of words that contain exactly 2 vowels.

Heres what I have so far. Can't get it into a method or to
count words with 2 vowels and I've lost a line of text and my
hair!! The file should read these 3 lines:
Mary had a little lamb
its fleece was white as snow
Understand

Please help.Oz

import java.util.*;
import java.io.*;
import UU.*;


public class mary3{
/*This class reads from a file and prints out details.*/

public static void main(String[]args)throws IOException {

String word, mary;

int count=0,vowels=0;
BufferedReader inFile = Text.open("a:mary.dat");//reads from file

mary = inFile.readLine();
word = inFile.readLine();

while (mary != null){
StringTokenizer t=new StringTokenizer (mary);
while (t.hasMoreTokens()){
mary=t.nextToken();
count++;
System.out.print(mary+" ");

}//end while


System.out.println();
mary = inFile.readLine();

}//end while
//inFile.close();
System.out.println();
System.out.print("There are "+count + " words in the text");
System.out.println();



while (word != null){
StringTokenizer w=new StringTokenizer (word);
while (w.hasMoreTokens()){
word=w.nextToken();
for(int i = 0; i < word.length(); i++){
switch(word.charAt(i)){
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
case 'A':
case 'E':
case 'I':
case 'O':
case 'U':
vowels++;
break;
default:
break;
} //end of for
} //end of switch



}//end inner while



System.out.println();
word = inFile.readLine();

}//end outside while




inFile.close();
//System.out.println();
//System.out.print("There are "+count + " words in the text");
System.out.println();
System.out.println("Total vowels = " + vowels);
System.out.println();

}//end of main
}//end of class

Output is:
Mary had a little lamb
Understand

There are 6 words in the text

Total vowels = 9

Process Exit...
