I have developed a search and replace function. How can I enhance it by adding a comment or alert to describe the pattern and incorporating a functional input box? Any suggestions are welcome!

<script language="javascript">
import java.util.regex.Pattern;
import java.util.regex.Matcher;
public class StringReplace {
public static void main(String[] args) {
String source = "The quick blue bird flies over the brown baseball field.";
String find = "blue";
String replace = "brown";
//
// Compiles the given regular expression into a pattern
//
Pattern pattern = Pattern.compile(find);
//
// Creates a matcher that will match the given input against the pattern
//
Matcher matcher = pattern.matcher(source);
//
// Replaces every subsequence of the input sequence that matches the
// pattern with the given replacement string
//
String output = matcher.replaceAll(replace);
System.out.println("Source = " + source);
System.out.println("Output = " + output);
}
}
