Java ArrayList toString() Method

Java ArrayList Java ArrayList

The toString() method converts an ArrayList object into a string.

The syntax of the toString() method is:

arraylist.toString()

Note:arraylist is an object of the ArrayList class.

Parameter Description:

  • None

Return Value

Returns the string representation of arraylist.

Example

Convert ArrayList to String type:

Example

import java.util.ArrayList;
import java.util.Comparator;
class Main {
    public static void main(String[] args){

        // Create a dynamic array
        ArrayList<String> sites = new ArrayList<>();
       
        sites.add("Example");
        sites.add("Google");
        sites.add("Wiki");
        sites.add("Taobao");
        System.out.println("Website list: " + sites);

        // Convert ArrayList to String type
        String list = sites.toString();
        System.out.println("String: " + list);
    }
}

Executing the above program produces the following output:

  
网站列表: [Example, Google, Wiki, Taobao]
String: [Example, Google, Wiki, Taobao]

In the above example, we created an array named sites.

Note this line:

String list = sites.toString();

We use the toString() method to convert the arraylist into a string. This method converts the entire arraylist into a String type.

Note: The ArrayList class does not have its own toString() method; it overrides the toString() method of the Object class.
