ArrayList get(index) Method in Java with Examples

The get(index) method of ArrayList in Java is used to retrieve the element at the specified index within the list.

Example 1: Here, we will use the get() method to retrieve an element at a specific index in an ArrayList of integers.

[10, 20, 30]
The element at index 2 is 30

Syntax of get(index) Method

get(int index)

• Parameter: The index of the element to be returned. It is of data-type int.
• Return Type: The element at the specified index in the given list.

If we try to access an index that is out of range i.e., index < 0 or index >= size(), an IndexOutOfBoundsExceptionwill be thrown.

Example 2: Here, we will demonstrate the error when attempting to access an index that is out of range.

Output:
