194. Method reference

Let's assume that we have the following Melon class and List of Melon:

public class Melon {  private final String type;  private int weight;  public static int growing100g(Melon melon) {    melon.setWeight(melon.getWeight() + 100);    return melon.getWeight();  }  // constructors, getters, setters, equals(),  // hashCode(), toString() omitted for brevity}List<Melon> melons = Arrays.asList(  new Melon("Crenshaw", 1200), new Melon("Gac", 3000),  new Melon("Hemi", 2600), new Melon("Hemi", 1600));

In a nutshell, method references are shortcuts for lambda expressions.

Mainly, method reference is a technique that's used to call a method by name rather than by a description of how to call it. The main benefit is readability.
