Java 101 dictates that every good equals( ) method should be paired with an equivalent hashCode( ), and the Arrays class is no exception Arrays defines both hashCode( ) and deepHashCode( ) methods for just this purpose I'll leave it to you to play with these, but they are self-explanatory:... particularly helpful if you have an array of numeric primitives, which is what Example 1-1 demonstrates (in varied and mostly useless ways) Example 1-1 Using the Arrays utility class package com.oreilly.tiger.ch01; import java. util.Arrays; import java. util.List; Chapter 1 What's New?
