❮ ArrayList Methods
Example
import java.util.ArrayList;
public class Main {
public static void main(String[] args) {
ArrayList<String> cars = new ArrayList<String>();
cars.add("Volvo");
cars.add("BMW");
cars.add("Ford");
cars.add("Mazda");
ArrayList cars2 = (ArrayList)cars.clone();
cars2.set(0, "Toyota");
System.out.println(cars);
System.out.println(cars2);
}
}Definition and Usage
The clone() method returns a copy of the ArrayList as an Object .
This creates a "shallow" copy, which means that copies of objects in the list are not created, instead the list has references to the same objects that are in the original list.
Note
Since the return type is Object , it must be type casted in order to use it as an ArrayList as shown in the example above.
Syntax
