Thanks for the prompt reply .

import java.util.*; import java.io.*; public class search2 { public static void main(String[]args) throws IOException { char awnChar, contiChar='y'; String awnser, conti, in, line; int word=0, sentence=0, vowel=0, consonants=0, digit=0, i=0, length = 0, lengthAll = 0; Scanner scan = new Scanner(System.in); //System.out.print("Enter the name of the file: "); //String fileName = scan.nextLine(); //File file = new File(fileName+".txt"); File file = new File("Quotation.txt"); Scanner input = new Scanner(file); while(input.hasNext()) { line = input.nextLine(); length = line.length(); lengthAll = length+lengthAll; } do { System.out.println("What would you like to determine? "); System.out.println("a.the number of words in the file "); System.out.println("b.the number of sentences in the file "); System.out.println("c.the number of vowels in the file "); System.out.println("d.the number of consonants in the file "); System.out.println("e.the number of digits (0 - 9) in the file "); System.out.println(); System.out.print("Input the letter: "); System.out.println(); awnser = scan.nextLine(); awnChar = awnser.charAt(0); if(Character.toLowerCase(awnChar) == 'a') { while(lengthAll>i) { in = input.next(); if (in.charAt(i) == ' ') word++; i++; } System.out.println("There are "+word+" word(s) in that document."); } else if (Character.toLowerCase(awnChar) == 'b') { while(lengthAll>i) { in = input.next(); if (in.charAt(i) == '?' || in.charAt(i) == '!' || in.charAt(i) == '.') sentence++; i++; } System.out.println("There are "+sentence+" sentence(s) in that document."); } i = 0; System.out.println("Would you like to continue? [Y/N] "); conti = scan.nextLine(); contiChar = conti.charAt(0); System.out.println(); }while(Character.toLowerCase(contiChar) == 'y'); } }

Would it be something like that? but i am still getting errors. Still very new at this :S

I am having trouble making a java program that reads a document and tells the user how many words there are in the document however it keeps giving me the following error:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String ind ex out of range: 4 at java.lang.String.charAt(String.java:687) at search2.main(search2.java:43) Press any key to continue . . .

this is what i got so far.

import java.util.*; import java.io.*; public class search2 { public static void main(String[]args) throws IOException { char awnChar, contiChar='y'; String awnser, conti, in; int word=0, sentence=0, vowel=0, consonants=0, digit=0, i=0, length = 0; Scanner scan = new Scanner(System.in); //System.out.print("Enter the name of the file: "); //String fileName = scan.nextLine(); //File file = new File(fileName+".txt"); File file = new File("Quotation.txt"); Scanner input = new Scanner(file); do { System.out.println("What would you like to determine? "); System.out.println("a.the number of words in the file "); System.out.println("b.the number of sentences in the file "); System.out.println("c.the number of vowels in the file "); System.out.println("d.the number of consonants in the file "); System.out.println("e.the number of digits (0 - 9) in the file "); System.out.println(); System.out.print("Input the letter: "); System.out.println(); awnser = scan.nextLine(); awnChar = awnser.charAt(0); if(Character.toLowerCase(awnChar) == 'a') { while(input.hasNext()) { in = input.next(); if (in.charAt(i) == ' ') word++; i++; } System.out.println("There are "+word+" word(s) in that document."); } else if (Character.toLowerCase(awnChar) == 'b') { while(input.hasNext()) { in = input.next(); if (in.charAt(i) == '?' || in.charAt(i) == '!' || in.charAt(i) == '.') sentence++; i++; } System.out.println("There are "+sentence+" sentence(s) in that document."); } i = 0; System.out.println("Would you like to continue? [Y/N] "); conti = scan.nextLine(); contiChar = conti.charAt(0); System.out.println(); }while(Character.toLowerCase(contiChar) == 'y'); } }

Any help appreciated. Thanks.
