In one of the previous examples, we covered how to sort an ArrayList in ascending order. In this post, you will learn how to sort ArrayList in descending order in Java. We will explore the following ways: Using the sort() method Using the Collections.sort() and Collections.reverse() ...
2. SortArrayListin Natural (Ascending) Order Thesort()is part of theListinterface and has been implemented inArrayListclass since Java 8. It takes aComparatorinstance used for enforcing the sorting order. Note thatArrayList.sort()method does the in-place sorting i.e. it modifies the original...
