Exercise To Lower

In the previous section we created a fresh clean OSGi enRoute demo application based on Angular and Bootstrap. In this section we have a number of exercises that you can use to find out if the explanations were sufficient. (If not, fork and send a pull request, we love to be forked!)

To Lower

The demo application turns the word into an upper case word. Let’s make the first exercise really trivial and turn it into lower case. The UpperApplication class contains the code that is called from the REST interface. You can change the method to:

public String getUpper(RESTRequest rq, String string) {
	return string.toLowerCase();
}
