In this blog, we are going to take a look at the support that Lambda provides in Java 8, especially in terms of using it to write aComparator and sort a Collection. Firstly, we define a simple class as follows:- public class Person { private String nameOfPerson; private int ageOfPerson; // standard constructors, getters/setters, equals and hashcode } Basic Sorting Without The Use of Lambdas The process of sorting a Collection, before Java 8, would involve creating an inner class for the comparator used in the class as :- new Comparator() { @Override public int compare( Person h1, Person h2) { return h1.getNameOfPerson().compareTo(h2.getNameOfPerson()); } }
