The size() method of AbstractSequentialList in Java is used to get the size for this instance of the AbstractSequentialList. It returns an integer value which is the size for this instance of the AbstractSequentialList.
Syntax:
public int size()
Parameters: This method does not accepts any parameter.
Returns: The method returns an integer value which is the size for this instance of the AbstractSequentialList.
Below examples illustrates the AbstractSequentialList.size() method:
Example 1:
// Java code to demonstrate the working of// size() method in AbstractSequentialList  import java.util.*;  public class GFG {    public static void main(String[] args)    {        // creating an AbstractSequentialList        AbstractSequentialList<Integer> arr            = new LinkedList<Integer>();          // using add() to initialize values        // [1, 2, 3, 4]        arr.add(1);        arr.add(2);        arr.add(3);        arr.add(4);          // print AbstractSequentialList        System.out.println("AbstractSequentialList: "                           + arr);          // Get the size        // using size()        System.out.println("Size: "                           + arr.size());    }} |
Output:
AbstractSequentialList: [1, 2, 3, 4] Size: 4
Example 2:
// Java code to demonstrate the working of// size() method in AbstractSequentialList  import java.util.*;  public class GFG {    public static void main(String[] args)    {        // creating an AbstractSequentialList        AbstractSequentialList<String> arr            = new LinkedList<String>();          // using add() to initialize values        // [Geeks, For, ForGeeks, GeeksForGeeks]        arr.add("Geeks");        arr.add("For");        arr.add("ForGeeks");        arr.add("GeeksForGeeks");          // print AbstractSequentialList        System.out.println("AbstractSequentialList: "                           + arr);          // Get the size        // using size()        System.out.println("Size: "                           + arr.size());    }} |
Output:
AbstractSequentialList: [Geeks, For, ForGeeks, GeeksForGeeks] Size: 4
