The Java collections framework is a set of interfaces and classes that make it easy to manage data in your applications. You can manage either ordered or unordered data and you can use one of four categories of classes. Each of these categories is represented by an interface named Set, List, Deque, and Map. To store a simple ordered collection, you usually want to use List.
- [Instructor] The Java Collections framework…is a set of interfaces and classes…that make it easy to manage data collections…in your applications.…You can manage either ordered or unordered data,…and you can use one of four categories of classes.…Each of these categories is represented by an interface.…On this page they're shown in the far left column,…and they're named Set, List, Deque, and Map.…And then across the top you'll see…the different types of collections within the categories.…So for example, let's say you wanted to create a list.…
A list is ordered data.…And you wanted it to be resizable.…You might then select the ArrayList class.…Now when you declare a collection object…it's traditional to set the type of the collection…as the interface.…And then when you instantiate the object…you use a constructor method for the concrete class…that you want to use.…So let's start in this project…where the main method is empty,…but I have a single object called clothing item.…I'm going to start by creating a list that contains strings.…
