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:

Example 1:

// 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()); 
    } 
} 

Output:

[Welcome, To, Geeks, For, Geeks]

Example 2:

// 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<Integer> abs 
            = new LinkedList<Integer>(); 
  
        // Use add() method 
        // to add elements to the Collection 
        abs.add(10); 
        abs.add(20); 
        abs.add(30); 
        abs.add(40); 
  
        // Using toString() method 
        System.out.println(abs.toString()); 
    } 
} 

Output:

[10, 20, 30, 40]
