In this program, we aresorting the given ArrayList in descending order. To sort an ArrayList in descending order, we need to passCollection.reverseOrder()as a second parameter in theCollections.sort()method as shown below. The same way, we can sort an ArrayList of integer type in descending...
In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Java...
