I am currently working on a method that has to return the number of newline characters, words, and characters of a string in an int[] array. I am confused on how count the number of times the Scanner.next() method runs. I have tried to use an if statement like this:

if (!(in.next() == ("")))
words++;


but I get java.util.NoSuchElementException. How would I get around the NoSuchElementException and count the tokens instead of returning them? Here is what I have so far:

import java.util.Scanner;

public class WordCount {

/**
 * Scans a string and returns the # of newline characters, words, and
 * characters in an array object.
 * 
 * @param text string to be scanned
 * @return # of newline characters, words, and characters
 */
public static int[] analyze(String text) 
 // Variables declared
 Scanner in = new Scanner(text);
 int[] values = new int[3];
 int line = 0;
 int words = 0;
 int characters = 0;

 // Checks string for # of newlines, chars, and words
 for (int i = 0; i < text.length(); i++) 
 char n = text.charAt(i);

 if (n == 'n') 
 line++;
 
 if (in.hasNext()) 
 characters++;
 

 //this is where I think the word count statement should go

 
 values[0] = line;
 values[1] = words;
 values[2] = characters;
 return values;


public static void main(String[] args) 
 analyze("This isn a test sentence.");

The test should return an array of 1, 5, 25.

For checking the amount of word in a string, you will need to check if the next character is a letter. At the same time, you will need a condition to check if it is end of the word.

boolean isEndWord = false;
// Checks string for # of newlines, chars, and words
for (int i = 0; i < text.length(); i++) 
 char n = text.charAt(i);
 if ((!Character.isLetter(n))&&isEndWord == true) 
 words++;
 isEndWord = false;
 
 if (n == ' ') 
 isEndWord = true;
 
 if (n == 'n') 
 line++;
 isEndWord = true;
 
 if (in.hasNext()) 
 characters++;
 

You can used the boolean isEndWord to trigger whenever the word ends.
