Justify text in Java

Question

I have to read in an integer which will be the length of the succeeding lines. (The lines of text will never be longer than the length provided).

I then have to read

Answer 1

I wrote a simple method to justify text. Its not 100% accurate, but works for the most part (since it ignores punctuations completely, and there might be some edge cases missing too). Also, Word justifies text in a richer manner (by not adding spaces to fill up the gap, but evenly distributing the width of a whitespace, which is tricky to do here).

public static void justifyText (String text) {
    int STR_LENGTH = 80;
    int end=STR_LENGTH, extraSpacesPerWord=0, spillOverSpace=0;
    String[] words;

    System.out.println("Original Text: \n" + text);
    System.out.println("Justified Text: ");

    while(end < text.length()) {

        if(text.charAt(STR_LENGTH) == ' ') {
            // Technically, this block is redundant
            System.out.println (text.substring(0, STR_LENGTH));
            text = text.substring(STR_LENGTH);
            continue;
        }

        end = text.lastIndexOf(" ", STR_LENGTH);
        words = text.substring(0, end).split(" ");
        extraSpacesPerWord = (STR_LENGTH - end) / words.length;
        spillOverSpace = STR_LENGTH - end + (extraSpacesPerWord * words.length);

        for(String word: words) {
            System.out.print(word + " ");
            System.out.print((extraSpacesPerWord-- > 0) ? " ": "");
            System.out.print((spillOverSpace-- > 0) ? " ": "");
        }
        System.out.print("\n");
        text = text.substring(end+1);

    }
    System.out.println(text);

}
