This example demonstrates how to read paragraphs from a CharSequence. A paragraph is a contiguous sequence of non-blank lines separated by one or more blank lines. The lines in a paragraph can be terminated with any of the legal line termination character sequences: \r, \r\n, or \n. 
    CharSequence inputStr = "a\r\rb"; // Mac
    inputStr = "a\r\n\r\nb";          // Windows
    inputStr = "a\n\nb";              // Unix
    
    // Compile the pattern
    String patternStr = "(^.*\\S+.*$)+";
    Pattern pattern = Pattern.compile(patternStr, Pattern.MULTILINE);
    Matcher matcher = pattern.matcher(inputStr);
    
    // Read the paragraphs
    while (matcher.find()) {
        // Get the paragraph
        String paragraph = matcher.group();
    }
