I\'m new to java (& to OOP too) and I\'m trying to understand about the class ArrayList but I don\'t understand how to use the get(). I tried searching in net, but could

Answer 1

To put it nice and simply, get(int index) returns the element at the specified index.

So say we had an ArrayList of Strings:

List names = new ArrayList();
names.add("Arthur Dent");
names.add("Marvin");
names.add("Trillian");
names.add("Ford Prefect");

Which can be visualised as: Where 0, 1, 2, and 3 denote the indexes of the ArrayList.

Say we wanted to retrieve one of the names we would do the following: String name = names.get(1); Which returns the name at the index of 1.

So if we were to print out the name System.out.println(name); the output would be Marvin - Although he might not be too happy with us disturbing him.
