Arraylist.get in java - Java ArrayList get() Method with Example

Arraylist.get in java: In the previous article we have discussed about Java ArrayList indexOf() Method with Example

In this article we are going to see the use Java ArrayList get() method along with suitable examples.

Java ArrayList get() Method with Example

get( ):

Java arraylist get: This java.util.ArrayList.get() method is used retrieve the element present in specified position.

It returns the element, which is present in the specified position of the ArrayList

If the index is out of the size/range of the arraylist then it shows IndexOutOfBoundException.

Syntax:

arrayListName.get()

Where,

arrayListName refers to the name of your ArrayList.

Let’s see different examples to understand it more clearly.

Example with String Type ArrayList
Example with Integer Type ArrayList

Method-1: Java ArrayList get() Method – Example with String Type ArrayList

Approach:

Create a new ArrayList of type String.
Add string elements into the ArrayList using the add() method.
Display the ArrayList elements.
Now get the element from a specific position in the ArrayList using get() method.
Print the element.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // Create a ArrayList of string datatype
        ArrayList<String> arr = new ArrayList<String>();
        // Adding some elements to the ArrayList
        arr.add("Hello");
        arr.add("this");
        arr.add("is");
        arr.add("an");
        arr.add("example of get() method");
        // Prints the ArrayList elements
        System.out.println("The elements of ArrayList are: "+arr);
        // get the element from arrayList using specific position
       System.out.println("Element at index 1: " + arr.get(1));
    }
}

Output:

The elements of ArrayList are: [Hello, this, is, an, example of get() method]
Element at index 1: this

Method-2: Java ArrayList get() Method – Example with Integer Type ArrayList

Approach:

Create a new ArrayList of type Integer.
Add Integer elements into the ArrayList using the add() method.
Display the ArrayList elements.
Now get the element from a specific position in the ArrayList using get() method.
Print the element.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // Create an ArrayList of Integer datatype
        ArrayList<Integer> arr = new ArrayList<Integer>();
        // Adding some elements to the ArrayList
        arr.add(2);
        arr.add(52);
        arr.add(13);
        arr.add(17);
        arr.add(1);
        // Prints the ArrayList elements
        System.out.println("The elements of ArrayList are: "+arr);
        // get the element from arrayList using specific position
       System.out.println("Element at index 1: " + arr.get(1));
    }
}

Output:

The elements of ArrayList are: [2, 52, 13, 17, 1]
Element at index 1: 52
