I am trying to understand exercise 5.2 of the Collections lecture named
Sort a list using Comparator
In the MyComparators class, don't understand the first line of the method
stringComparator(), it has a return statement at the first line, not sure
how that works or the purpose it serves, there is also another return
statement at the bottom of the method.
I also notice there is a compare method which never gets used when the
class is called from the main class, what is the intent of that method,? if
any.
public class MyComparators {
// String Comparator object
public static Comparator stringComparator() {
return new Comparator() {
public int compare(Object o1, Object o2) {
Thanks
