Alternatively, the Comparator class provides a factory method to build afunction using Lambda Expressions. Since the Java 8 release, we can addstatic methods in interfaces. TheComparatorinterface’s staticcomparing()method accepts a function that returns aComparatorthat contains the comparison logic to...
A JavaTreeSetcollection that implements the Set interface is a unique collection of sorted elements. This means when we add elements to a TreeSet, it stores them in a sorted manner. Tosort aHashMapinstance using aTreeSet, we can create aTreeSetinstance and dump all theHashMapelements into...
