Let's assume I have the string:
"I like visiting http://www.google.com and www.apple.com"
How can I tokenize this string, and determine if the token contains a URL?

public class URLInString {
public static void main(String[] args) {
String s = args[0];
// separete input by spaces ( URLs don't have spaces )
String [] parts = s.split("\\s");
// Attempt to convert each item into an URL.
for( String item : parts ) try {
URL url = new URL(item);
// If possible then replace with anchor...
System.out.print("<a href=\"" + url + "\">"+ url + "</a> " );
} catch (MalformedURLException e) {
// If there was an URL that was not it!...
System.out.print( item + " " );
}
System.out.println();
}
