Processing RSS feeds in java

Problem:

Create a program that processes RSS feeds of the website LAU (lau.edu.lb). The links of RSS feeds are (http://www.lau.edu.lb/news-events/news/rss.xml). Don't forget to print the web stories' titles.

Output:

There are 10 web stories.
Education: a continuous process
Building an accessible campus
Stop underage marriage!
Architecture, Politics and Society
What are pharmacists to public health?
Going off script
For the love of science
The perfect bridge
The Arab world?s future diplomats
Roadmap to residency
