Date: Sun, 30 Jun 2013 17:10:18 +0200

Hello,

I'm learning java today from

http://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html

and I have problem with age of Fred from RosterTest.java

http://docs.oracle.com/javase/tutorial/displayCode.html?code=http://docs.oracle.com/javase/tutorial/java/javaOO/examples/RosterTest.java

Returned value from method

today.get(Calendar.MONTH)

is 5 and today is June.

According to Sharon, the Date and Calendar classes are being obsoleted in JDK8. It might be best to either change the example to use the new Date-Time APIs or to use something else altogether.
