A TreeMap automatically sorts the keys in their natural order or according to a specified comparator. import java.util.Map; import java.util.TreeMap; public class SortMapByKeys { public static void main(String[] args) { Map<String, Integer> map = new TreeMap<>(); map.put("Banana", ...
The function returns the string length of the passed value. It serves as a key for the comparator object. var sorted = words.stream().sorted(Comparator.comparing(strLen)).toList(); We pass our key-extractor function toComparator.comparing, which generates a comparator for thesortedmethod. $ ...

TableRowSorter uses java.util.Comparator objects to sort its rows. A class that implements this interface must provide a method called compare that defines how any two objects are compared for the purpose of sorting. For example, the following code creates a Comparator that sorts a set of strin...
