In this course, you'll be introduced to Java collections and explore the details of how the Lists part of the Collections framework works. You'll start by learning how arrays are a rudimentary form of containers with some similarities to ArrayLists. Next, you'll explore the limitations of arrays, namely their fixed length and limited API support. You'll then move on to ArrayLists and explore how ArrayLists mitigate the weaknesses of arrays while still retaining their advantages. You'll learn how to instantiate an ArrayList and iterate over it using while loops, ordinary for-loops, and enhanced for-loops. Finally, you'll examine how to access and modify specific elements in an ArrayList.

WHAT YOU WILL LEARN

  • discover the key concepts covered in this course
    construct arrays to contain objects of various types
    describe the two limitations of an array
    describes the is-a relationship of an ArrayList with Collection, Iterable, and List
    describe how an ArrayList is ordered and allows duplicates
  • recognize the individual methods from the collection interface
    recognize how the Iterable and Iterator interfaces can be accessed using loops to avoid run-time errors from going over the limits of a list
    recognize how the .get method can be used to access individual elements of a list
    summarize the key concepts covered in this course
