Complete Java SE 8 Developer Bootcamp - Limitations of Collections

The video tutorial explains the advantages of using collections over arrays, particularly their ability to dynamically grow and shrink. It highlights the limitations of collections, such as the inability to store primitive data types directly, and introduces wrapper classes as a solution. The concept of autoboxing in Java is discussed, which allows automatic conversion between primitives and their corresponding wrapper objects. The tutorial also covers the use of wrapper classes to add functionality to primitives and the role of polymorphism in collections, emphasizing the need for casting when retrieving objects.
