Codecademy Learn Java, ArrayList Insertion, Data Structures

Lesson Summary

In this Codecademy Learn Java lesson we are looking at inserting values into our ArrayList in a new way. In the previous lesson we learned how to use the add method to add integers into our quizGrades list. In this specific lesson we learn that we can call the add method and provide an index as the first parameter and an integer value as the second parameter and that value will be added to that specific index in our quizGrades array. All the other values will shift one up in value.
