Complete Java SE 8 Developer Bootcamp - Polymorphism Revisited

The video tutorial explains the concept of arrays and polymorphism in programming. It introduces a class hierarchy involving Person, Employee, Manager, and Secretary, and demonstrates how polymorphism allows different objects to be stored in an array of a common type. The tutorial covers array operations, including subscripting and casting, and discusses the limitations of accessing subclass-specific methods. It also explains how to iterate through arrays using traditional for loops and for-each loops, highlighting the redundancy of explicitly calling the toString method when printing objects.
