# Objects, immutability and switch expressions
2-
This chapter includes 18 problems that involves objects, immutability and switch expressions. The chapter starts with several problems about dealing with null references. It continues with problems regarding checking indexes, **equals()** and **hashCode()**, and immutability (e.g., writing immutable classes, passing/returning mutable objects from immutable classes). The last part of the chapter deals with cloning objects and JDK 12 switch expressions.
