wrong values

[mark-mlt]

i want to get the number of words loaded from an array: i did this >

public static void countWords() {
		FileLoader.fileLines();
		String lineContent = new String();
		for (int i = 0; i < fileLines.size(); i++) 
		{
			// get a line of text from the file
			{
				lineContent += String.format("%s", fileLines.get(i));
				String str = lineContent;
		        StringTokenizer st = new StringTokenizer (str);

		        System.out.println("number of wds: " +st.countTokens());
		        str.isEmpty();
			}
		}

but it is overwriting the sentece every time so it is giving me the wrong value. any help is welcom :)

What you mean here, want to count words in an arrray, or counts words in a line of text?

the line of a text

Why you doing too much things there? I think there is a space between each two words. Using StringTokenizer, you can do it easily. Try the following.

        String str = "Count numner of words here.";
        
        StringTokenizer st = new StringTokenizer(str, " ");
        
        System.out.println(st.countTokens());

yes that works, but i want to populate

String str = "Count numner of words here.";

from an array

Yes you can, but the problem is defining the array length. Because the length should be a constant value. So the solution is List or ArrayList. Do you how to work on with them?

the text file i am reading from:
one two three four five six seven
one two three four five six
one two three
one two
one

-------------------------------------------------------------------
by the code below, im counting the words but giving me wrong values.
-------------------------------------------------------------------

public static void countWords() {
		FileLoader.fileLines();
		String lineContent = new String();
		for (int i = 0; i < fileLines.size(); i++) 
		{
			// get a line of text from the file
			{
				lineContent += String.format("%s", fileLines.get(i));
				String str = lineContent;
		        StringTokenizer st = new StringTokenizer (str);

		        System.out.println("number of wds: " +st.countTokens());
			}
		}

I'm not clear how you are handle some variables. Specially what you try to do here?

String lineContent = new String();

Try the following, it's not difficult if you get correctly what I have post with in my last code. ;) Only thing you have to do is, looping through the all strings you have.

    public void countWords() {        
        String[] tens = {"one two three four five six seven",
                         "one two three four five six",
                         "one two three",
                         "one two",
                         "one"};        
        
        for(int i = 0; i < tens.length; i++) {
            StringTokenizer st = new StringTokenizer(tens[i], " ");

            System.out.println("number of wds: " + st.countTokens());
        }
    }
