In this Java Challenger you’ll learn how equals() and hashcode() combine to make object comparisons efficient and easy in your Java programs. Simply put, these methods work together to verify if two objects have the same values.  

Without equals() and hashcode() we would have to create very large “if” comparisons, comparing every field from an object. This would make code really confusing and hard to read. Together, these two methods help us create more flexible and cohesive code.
