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"? |

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. |
