Question

I wonder how can I change my code so, that the number of given value words was specified in another class. And in construction class I need to make a method that prints in every given value. Here is my code:

public void wordBox()
    {
        for (int i = 0; i < words.length(); i++)
        {
        if (words.length() % wordsPerLine == 0 && words.charAt(wordsPerLine) == ' ')
            System.out.println();               
        else 
            System.out.print(words.charAt(i));
        }
        System.out.println();
    }

wordsPerLine was given in another class as a number of 3.
String is this:”the quick brown fox jumped over the lazy dog”

output should be look like:

the quick brown

fox jumped over

the lazy dog

Note: I am not allowed to use any other classes like token or buffer. Also, I cannot use replace/split. So, this is what I was given and I need to work from that.

Any help will be appreciated.
Thanks

Rather than making words and wordsPerLine instance variables that are set in the constructor, make them parameters passed to your static method, like this:

public static void wordBox(String words, int wordsPerLine) {
    int count = 1;
    for (int i = 0; i < words.length(); i++)
    {
    if (words.charAt(i) == ' ' && (count++) % wordsPerLine == 0)
        System.out.println();               
    else 
        System.out.print(words.charAt(i));
    }
    System.out.println();
}

This way you would be able to specify words and wordsPerLine independently of the constructor, and call wordBox from anywhere with any combination of words and the desired number of words per line.
