Thread: Need help with While and For Statements

Okay, the code below works fine, it prompts the user to enter a sentence, makes sure it is a proper sentence, then checks how many words there are. What I want it to do is prompt the user over and over again (keeping track of the sentences entered) until one of the sentences contains a 'q' or a 'Q'. I've been trying to put another while around the whole thing but that doesn't work. I really am stuck.

import javax.swing.*;
 
public class ChurchAustinA2Q2 {
 
  public static void main (String [] args) {
 
 
    String prompt = "Enter one sentence. " ;
    String input ;
 
    boolean inputOk = false ;
 
    int loc ;
    int loc2 ;
    int letterCount = 0 ;
    int wordCount = 0 ;
    int charCount = 0 ;
    int sentenceCount = 0 ;
 
    char ch = 'x' ;
 
 
    input = JOptionPane.showInputDialog(null, prompt) ;
    input = input.trim() ;
    loc = input.length() ;
 
    while ( ! inputOk ){
		if ( input.charAt(loc-1) == ( '!' ) ){
			inputOk = true ;
		}
		else if ( input.charAt(loc-1) == ( '.' ) ){
			inputOk = true ;
		}
		else if ( input.charAt(loc-1) == ( '?' ) ){
			inputOk = true ;
		}
		else{
			inputOk = false ;
			input = JOptionPane.showInputDialog(null, "That is not a proper sentence. " + prompt) ;
			input = input.trim() ;
    		loc = input.length() ;
		}
	}
 
 
	for ( loc2 = 0 ; loc2 < input.length() ; loc2++ ){
		ch = input.charAt(loc2);
		charCount++ ;
 
		if (( 'a' <= ch && ch < 'z' ) || ( 'A' <= ch && ch <= 'Z' ) || ( ch == 39 ) ) {
			letterCount++ ;
		}
		else{
 
			if ( letterCount > 0 ){
				wordCount++ ;
				letterCount = 0 ;
			}
		}
	}
 
 
 
	System.out.println("\n") ;
	System.out.println("Sentence Statistics ") ;
	System.out.println("=================== ") ;
	System.out.println("Sentences: " + sentenceCount) ;
	System.out.println("Words: " + wordCount) ;
	System.out.println("Word Characters: " + (charCount - wordCount) ) ;
	System.out.println("\n") ;
	System.out.println("A / a = ") ;
	System.out.println("E / e = ") ;
	System.out.println("I / i = ") ;
	System.out.println("O / o = ") ;
	System.out.println("U / u = ") ;
	System.out.println("\n") ;
	System.out.println("Average Word Length: ") ;
	System.out.println("Average Vowels Per Word: ") ;
 
  }
}

Yeah, that's what I was doing before but it was not working properly for some reason. I figured out what I was doing wrong now though. Thanks, anyways.
