AbstractSequentialList toString() method in Java with Example

The toString() method of Java AbstractSequentialList is used to return a string representation of the elements of the Collection.

The String representation comprises a list representation of the elements of the Collection in the order they are picked by the iterator closed in square brackets[].This method is used mainly to display collections other than String type(for instance: Object, Integer)in a String Representation.

Syntax:



public String toString()

Parameter The method does not take any parameters.

Return This method returns a String representation of the collection.

Below examples illustrate the toString() method:

// Java program to demonstrate
// Abstract Collection toString() method
  
import java.util.*;
  
public class collection {
    public static void main(String args[])
    {
        // Creating an Empty AbstractSequentialList
        AbstractSequentialList<String> abs
            = new LinkedList<String>();
  
        // Use add() method
        // to add elements to the Collection
        abs.add("Welcome");
        abs.add("To");
        abs.add("Geeks");
        abs.add("For");
        abs.add("Geeks");
  
        // Using toString() method
        System.out.println(abs.toString());
    }
}
