Manipulating text from the file

[ast_993]

The code prints different reports my question is how to print the text from the file in columns of 5 words each per line. The method that supposed to do that, is public void printTokens() but not sure if the loop is properly set up.

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
import java.util.StringTokenizer;


public class WordsManipulationClient {


public static void main(String[] args)
{
WordFrequencyService service1 = new WordFrequencyService();
service1.readPrintText();
System.out.println();
service1.storeTokens();
System.out.println();
service1.printTokens();


}//end main

}//end WordsManipulationClient



class WordFrequencyService
{
String[] words = new String [300];
int count;


public void readPrintText()
{


Scanner scan = new Scanner(System.in);

Scanner fileScan;
boolean validName = false;


do
{

System.out.print("Enter file name: ");
String str1 = scan.nextLine();

try
{

fileScan = new Scanner (new File(str1));
validName = true;

int lineCount =0;

System.out.println("\tReport1 - Text in Data File");
System.out.println();
System.out.println("-------------------------------------------------------");
while (fileScan.hasNextLine( ))

{


String str = fileScan.nextLine();
System.out.println(str);
lineCount++;


}//end while

System.out.println();
System.out.println("Number of Lines Read = " + lineCount);
System.out.println("-------------------------------------------------------");
fileScan.close();
}//end try

catch(FileNotFoundException fnfe)
{
System.out.println("Invalid File name; enter again");
}
}while(!validName);

}//end ReadPrintText();


public void storeTokens()
{

Scanner scan = new Scanner(System.in);

Scanner fileScan;
boolean validName = false;


do
{

System.out.print("Enter file name: ");
String str1 = scan.nextLine();

try
{

fileScan = new Scanner (new File(str1));
validName = true;

int count = 0;

while(fileScan.hasNext())
{

String str = fileScan.nextLine();
StringTokenizer tokens = new StringTokenizer(str,",;.");;
while(count<300 && tokens.hasMoreTokens())
{
String aToken = tokens.nextToken();
words[count] = aToken;
count++;


}

}



fileScan.close();
}//end try

catch(FileNotFoundException fnfe)
{
System.out.println("Invalid File name; enter again");
}
}while(!validName);

}//end storeTokens


public void printTokens()
{
System.out.println();
System.out.println("\tReport2 - Words without punctuation");
System.out.println();
System.out.println("-------------------------------------------------------");

for (int i =0; i<words.length; i++)
{


System.out.println(words[count]);

}

System.out.println();
System.out.println("-----------------------------------------------------------");
}



}

well... does it "print the text from the file in columns of 5 words each per line"?

No it prints nothing

that should answer your question -- something is not setup as you think you've set it up. Time to step back and verify the steps that you are taking.

When everything else fails. Try again. That's how you learn.
