AbstractSequentialList toArray() method in Java with Example

The toArray() method of Java AbstractSequentialList is used to form an array of the same elements as that of the AbstractSequentialList. Basically, it copies all the element from a AbstractSequentialList to a new array.

Syntax:

Object[] arr = AbstractSequentialList.toArray()

Parameters: The method does not take any parameters.

Return Value: The method returns an array containing the elements similar to the AbstractSequentialList.

Below programs illustrate the AbstractSequentialList.toArray() method:

        // Creating an empty AbstractSequentialList
        AbstractSequentialList<String>
            abs_col = new LinkedList<String>();
  
        // Use add() method to add
        // elements into the AbstractSequentialList
        abs_col.add("Welcome");
        abs_col.add("To");
        abs_col.add("Geeks");
        abs_col.add("For");
        abs_col.add("Geeks");
  
        // Displaying the AbstractSequentialList
        System.out.println("The AbstractSequentialList: "
                           + abs_col);
  
        // Creating the array and using toArray()
        Object[] arr = abs_col.toArray();
  
        System.out.println("The array is:");
        for (int j = 0; j < arr.length; j++)
            System.out.println(arr[j]);
    }
}

                        filter_none









Output:


The AbstractSequentialList: [Welcome, To, Geeks, For, Geeks]
The array is:
Welcome
To
Geeks
For
Geeks
