I can't see any difference between this default sort method(from java.util.Collections)
public static <T extends Comparable<? super T>> void sort(List<T> list) {
//implementation
}
..and this :
public static <T extends Comparable<T>> void mySort(List<T> list) {
//implementation
}
Although I know about the differences between the 'upper' and 'lower' bounded wildcards,I still don't understand why they use '? super T' instead of simple 'T' in this case.If I use these methods,I get the same result with both of them.Any suggestions?
