Java ArrayList toString()

The syntax of the toString() method is:

arraylist.toString()

Here, arraylist is an object of the ArrayList class.

toString() Parameters

The toString() method doesn't take any parameters.

toString() Return Values

• returns a string representation of the arraylist

Example: Convert ArrayList to String

Output

ArrayList: [Java, Python, C]
String: [Java, Python, C]

In the above example, we have created an arraylist named languages. Notice the line,

String list = languages.toString();

Here, we have used the toString() method to convert the arraylist into a string. The method converts the entire arraylist into a single String.

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