Java ArrayList get()

The syntax of the get() method is:

arraylist.get(int index)

Here, arraylist is an object of the ArrayList class.

get() Parameter

The get() method takes single parameter.

• index - position of the element to be accessed

get() Return Value

• returns the element present in the specified position.
• raises IndexOutOfBoundsException, if index is out of the range.

Example 1: get() Method with String ArrayList

import java.util.ArrayList;

class Main {
    public static void main(String[] args) {
        // create an ArrayList
        ArrayList<String> languages = new ArrayList<>();

        // insert element to the arraylist
        languages.add("JavaScript");
        languages.add("Java");
        languages.add("Python");
        System.out.println("Programming Languages: " + languages);

        // access element at index 1
        String element = languages.get(1);
        System.out.println("Element at index 1: " + element);
    }
}

Output

Programming Languages: [JavaScript, Java, Python]
Element at index 1: Java

In the above example, we have created an arraylist named languages. Here, the get() method is used to access the element present at index 1.

Example 2: get() Method with Integer ArrayList

import java.util.ArrayList;

class Main {
    public static void main(String[] args) {
        // create an ArrayList
        ArrayList<Integer> numbers = new ArrayList<>();

        // insert element to the arraylist
        numbers.add(22);
        numbers.add(13);
        numbers.add(35);
        System.out.println("Numbers ArrayList: " + numbers);

        // return element at position 2
        int element = numbers.get(2);
        System.out.println("Element at index 2: " + element);
    }
}

Output

Numbers ArrayList: [22, 13, 35]
Element at index 2: 35

Here, the get() method is used to access the element at index 2.

Note: We can also get the index number of an element using the indexOf() method. To learn more, visit Java ArrayList indexOf().
