    e445.  
    Reading Lines from a String Using a Regular Expression</h3>

This example demonstrates how to read lines from a <code>CharSequence</code>.  The
lines can be terminated with any of the legal line termination
character sequences: \r, \r\n, or \n.


<pre>
    CharSequence inputStr = <font color="#0066ff"><i>"a\rb"</i></font>; // Mac
    inputStr = <font color="#0066ff"><i>"a\r\nb"</i></font>;            // Windows
    inputStr = <font color="#0066ff"><i>"a\nb"</i></font>;              // Unix
    
    // Compile the pattern
    String patternStr = "^(.*)$";
    Pattern pattern = Pattern.compile(patternStr, Pattern.MULTILINE);
    Matcher matcher = pattern.matcher(inputStr);
    
    // Read the lines
    while (matcher.find()) {
        // Get the line with the line termination character sequence
        String lineWithTerminator = matcher.group(0);
    
        // Get the line without the line termination character sequence
        String lineWithoutTerminator = matcher.group(1);
    }
