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() ...

1. Different Ways to Sort an ArrayList AnArrayListis an ordered and unsorted collection of elements and is part of theJava Collections framework, similar to other classes such asLinkedListorHashSet.By default, elements added in theArrayListare stored in the order they are inserted. When we need...
Enter the size of the array, and then enter all the elements of that array. Then, the program uses a for loop to sort the array in ascending order by comparing each element of the array with all the other elements in the array. If an element is smaller than the other elements, it ...

在 sortAscending()方法中,我们调用了 Collections.sort()方法,并传递这个初始化的 ArrayList对象为参数,返回排序后的 ArrayList。在 sortDescending()方法中,我们调用重载的 Collections.sort()方法让其按照降序对元素排序,这个版本的 Collections.sort()接收ArrayList对象作为第一个参数,一个由 Collections.reverseOrder(...
