Method

ListgetWordWrappedText(int maxWidth, String... lines)
This method will calculate word wrappings given a number of lines of text and how wide the text can be printed. 
if (maxWidth <= 0) {
    return Arrays.asList(lines);
List<String> result = new ArrayList<String>();
LinkedList<String> linesToBeWrapped = new LinkedList<String>(Arrays.asList(lines));
while (!linesToBeWrapped.isEmpty()) {
    String row = linesToBeWrapped.removeFirst();
    int rowWidth = getColumnWidth(row);
...
StringgetWrappedLine(String line, int lineLength)
Inserts newlines at or before lineLength at spaces or commas. 
if (line.length() <= lineLength) {
    return line;
StringBuffer result = new StringBuffer();
char[] lineChars = line.toCharArray();
int lastBreakCharIdx = -1;
ArrayList<Integer> breakPoints = new ArrayList<Integer>();
for (int i = 0; i < lineChars.length; i++) {
...
ListlineWrap(String text, int width, boolean shiftNewLines)
line Wrap 
String[] words = text.trim().split(" ");
StringBuilder currentLine = new StringBuilder();
List<String> newLines = new ArrayList<String>();
int currentLength = 0;
for (int i = 0; i < words.length; i++) {
    currentLine.append(words[i] + " ");
    currentLength = currentLine.length();
    int nextWordLength = 0;
...
String[]wordWrap(final String rawString, final int lineLength)
word Wrap 
if (rawString == null) {
    return new String[] { "" };
if ((rawString.length() <= lineLength) && (!rawString.contains("\n"))) {
    return new String[] { rawString };
final char[] rawChars = (rawString + ' ').toCharArray();
StringBuilder word = new StringBuilder();
...
ListwordWrap(String entry)
word Wrap 
int ind = 0;
List<String> out = new ArrayList<>();
while (ind <= entry.length()) {
    int nind = ind + 40;
    if (nind < entry.length()) {
        if (entry.charAt(nind) != ' ') {
            while (entry.charAt(nind) != ' ' && nind != 0) {
                nind--;
...
ListwordWrap(String input, int width)
word Wrap 
ArrayList<String> output = new ArrayList<>();
final char[] chars = input.toCharArray();
final int N = input.length();
if (N < width) {
    return Arrays.asList(input.split("\n"));
int prevLine = 0;
while (true) {
...
StringwrapString(String str)
wrap String 
return wrapString(str, MAX_LENGTH);
ListwrapString(String text, int maxLength)
wrap String 
List<String> tmpStrings = new ArrayList<String>();
if (text == null) {
    return tmpStrings;
text = text.trim();
if (text.length() <= maxLength) {
    tmpStrings.add(text);
    return tmpStrings;
...
ListwrapText(String description)
wrap Text 
description = description.trim();
return Arrays.asList(description.split("\n"));
StringwrapText(String inString, String newline, int wrapColumn)
Lines wraps a block of text. 
StringTokenizer lineTokenizer = new StringTokenizer(inString, newline, true);
StringBuffer stringBuffer = new StringBuffer();
while (lineTokenizer.hasMoreTokens()) {
    try {
        String nextLine = lineTokenizer.nextToken();
        if (nextLine.length() > wrapColumn) {
            nextLine = wrapLine(nextLine, newline, wrapColumn);
        stringBuffer.append(nextLine);
    } catch (NoSuchElementException e) {
        break;
return (stringBuffer.toString());
