If I use java.util.Date as the "key" for a TreeMap. When I add objects, does TreeMap automatically sort the "key" by ascendant order of "Date" ?

Depends on the constructor you used. What does the Javadoc for TreeMap say?

The java.util.Date class implements the Comparable interface. so even if you use the default TreeMap constructor then on putting the java.util.Date as Key the TreeMap will automatically sort by asc order of date
