There are various types of sort algorithms defined in Java that are useful based on the complexity of the structure. Below is the code block that defines overriding the comparator interface to give our implemen
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 Jav...

This sort isguaranteed to be stable. It means that equal elements will not be reordered as a result of the sort. The specifiedlistmust be modifiable, but need not to be resizable. Thesort()does not return any value. 1.1. Sorting an ArrayList of Strings ...
We introduced the notion of a Comparator in Java, which is used to specify the sort order of a particular class. Let's start with an example to sort Strings by their length. We thus want to write a Comparator that compares Strings. So the general format of our Comparator will be as ...
