You want to wrap lines of text using different line widths and various line termination sequences.

Use WordUtils to wrap words. Supply the number of columns and a line termination string, and WordUtils will wrap text. The following example wraps a small string to 20 columns:

// Define original String
String message = "One Two Three Four Five";
// Wrap the text.
String wrappedString = 
    WordUtils.wrapText( message, 20, "\n", false );
System.out.println( "Wrapped Message:\n\n" + wrappedString );

This produces the following output:

Wrapped Message:
One Two Three Four 
Five

When WordUtils wraps a string, it takes a user-supplied line termination sequence like \n or \r\n and inserts this line termination sequence after a specified number of characters, without splitting a word. In the next example, if the user is using a hand-held device, the number of columns in the display is 40, and a new line is represented by the sequence \r\n. On a workstation, the number of available columns is 80, and a new line is a single \n character. The platform is available as the System property application.platform:

String message = "Four score and seven years ago, our fathers " +
                 "brought forth upon this continent a new nation: " +
                 "conceived in liberty, and dedicated to the proposition " +
                 "that all men are created equal. ";
// Define variables to hold two parameters to word wrapping 
int cols; 
String lineSeparator = "";
// Retrieve the platform property from System 
String platform = System.getProperty("application.platform");
if( platform.equals( "Handheld" ) ) {
    cols = 40;
    lineSeparator = "\r\n";
} else if( platform.equals( "Workstation" ) {
    cols = 80;
    lineSeparator = "\n";
}
// Wrap the text.
String wrappedString = 
    WordUtils.wrapText( message, cols, lineSeparator, true );

Depending on the platform, the wrappedString variable now holds the initial paragraph of the Gettysburg Address wrapped to fit either a 40-column handheld device or an application running on a workstation with an 80-column display.

To wrap text for presentation on the Web, use the line termination sequence <br/> to add an HMTL line break. The following example wraps text with <br/>, and introduces an option to prevent WordUtils from wrapping larger words:

String message = "Four score and seven years ago, our fathers " +
                 "brought forth upon this continent a new nation: conceived " +
                 "in liberty, and dedicated to the proposition that all men " +
                 "are created equal. http://www.oreilly.com/Gettysburg ";
// Wrap the text.
String wrappedString = WordUtils.wrap( message, 40, "<br/>", false );

In this example, the Gettysburg Address is formatted to fit into 40 columns in an HTML document. The final parameter to the WordUtils.wrap( ) method tells the wrapping algorithm not to bother wrapping large words, such as the long URL at the end of the text. Wrapping a long word would prevent people from being able to copy this URL correctly.
