ArrayList Class get() method

• get() method is available in java.util package.
• get() method is used to retrieve the element at the given index in this Arraylist.
• get() method is a non-static method so it is accessible with the class object and if we try to access the method with the class name then we will get an error.
• get() method may throw an exception at the time of returning an element of the given indices.
  IndexOutOfBoundsException:- This exception may throw when the given indices are not in a range.

Syntax:

    public T get(int indices);

Parameter(s):

• int indices – represents the index of the element to retrieve.

Return value:

The return type of this method is T, it returns the element at the given index in this Arraylist.

Example:

// Java program to demonstrate the example 
// of T get(int) method of ArrayList.

import java.util.*;

public class GetOfArrayList {
    public static void main(String[] args) {
        // Create an ArrayList with initial 
        // capacity of storing elements

        ArrayList < String > arr_l = new ArrayList < String > (10);

        // By using add() method is to add 
        // elements in this ArrayList
        arr_l.add("C");
        arr_l.add("C++");
        arr_l.add("JAVA");
        arr_l.add("DOTNET");
        arr_l.add("PHP");

        // Display ArrayList
        System.out.println("ArrayList Elements :" + arr_l);

        // By using get(int) method is to return the
        // element at the given index in this ArrayList
        String element = arr_l.get(2);

        // Display Returned Element
        System.out.println("arr_l.get(2) : " + element);
    }
}

Output

ArrayList Elements :[C, C++, JAVA, DOTNET, PHP]
arr_l.get(2) : JAVA
