Use the Custom Comparator to Specify the Element Ordering in C++ At first, we define avectorof strings used to initialize apriority_queue. Next, a lambda expression is defined to form the comparator function. The latter compares two strings by length. Now, we can declare apriority_queueobject...
Let’s redefine the custom ordering usingJava 8 lambda based comparatorsyntax and verify the result. We are using constructorPriorityBlockingQueue(int initialCapacity, Comparator comparator). //Comparator for name field Comparator<Employee> nameSorter = Comparator.comparing(Employee::getName); PriorityBloc...
