Java ArrayList get() Usage and Example

Java ArrayList Methods

The Java ArrayList get() method returns the element existing at the specified position.

The syntax of the get() method is:

arraylist.get(int index)

get() parameter

index - Position of the element to be accessed

get() return value

Returns the element existing at the specified position.

Note: If the index is out of range, the get() method will throw an exception exception IndexOutOfBoundsException.

Example1: get() method with string ArrayList

Example

import java.util.ArrayList;
class Main {
　　　　public static void main(String[] args) {
　　　　　　　　//Create ArrayList
　　　　　　　　ArrayList<String> languages = new ArrayList<>();
　　　　　　　　//Insert Element into ArrayList
　　　　　　　　languages.add("JavaScript");
　　　　　　　　languages.add("Java");
　　　　　　　　languages.add("Python");
　　　　　　　　System.out.println("Programming languages: "　+　languages);
　　　　　　　　//Access index1element at the location
　　　　　　　　String element = languages.get(1);
　　　　　　　　System.out.println("Index1: element: "　+　element);
　　　　}
}

Output Result

Programming languages: [JavaScript, Java, Python]
Index1: Java

In the above example, we created an array list named languages. Here, the get() method is used to access the element at the index1elements exist at the location.

Example2: get() method with integer ArrayList

Example

import java.util.ArrayList;
class Main {
　　　　public static void main(String[] args) {
　　　　　　　　//Create ArrayList
　　　　　　　　ArrayList<Integer> numbers = new ArrayList<>();
　　　　　　　　//　Insert Element into ArrayList
　　　　　　　　numbers.add(22);
　　　　　　　　numbers.add(13);
　　　　　　　　numbers.add(35);
　　　　　　　　System.out.println("Number ArrayList: "　+　numbers);
　　　　　　　　//Return Position2element
　　　　　　　　int element = numbers.get(2);
　　　　　　　　System.out.println("Index2element: "　+　element);
　　　　}
}

Output Result

Number ArrayList: [22,　13,　35]
Index2: element:　35

Here, the get() method is used to access the element at the index2element at the location.

NoteWe can also use the indexOf() method to obtain the index value of the element (number). For more information, please visitJava ArrayList indexOf().
