The addAll(int index, Collection C) method of AbstractSequentialList is used to append all of the elements from the collection passed as a parameter to this function at a specific index or position of a abstract sequential list.
Syntax:
boolean addAll(int index, Collection C)
Parameters: This function accepts two parameters as shown in the above syntax and are described below.
- index: This parameter is of integer datatype and specifies the position in the list starting from where the elements from the container will be inserted.
- C: It is a collection whose elements are needed to be appended.
Return Value: The method returns TRUE if at least one action of append is performed.
Below programs illustrate the Java.util.AbstractSequentialList.addAll() method:
Example 1:
// Java code to illustrate addAll() method  import java.util.*;import java.util.AbstractSequentialList;  public class AbstractSequentialListDemo {    public static void main(String args[])    {          // Creating an empty AbstractSequentialList        AbstractSequentialList<String>            absqlist = new LinkedList<String>();          // Use add() method to add elements        absqlist.add("Geeks");        absqlist.add("for");        absqlist.add("Geeks");        absqlist.add("10");        absqlist.add("20");          // Creating a Collection        Collection<String>            collect = new ArrayList<String>();        collect.add("A");        collect.add("Computer");        collect.add("Portal");        collect.add("for");        collect.add("Geeks");          // Displaying the list        System.out.println("AbstractSequentialList: "                           + absqlist);          // Appending the collection to the list        absqlist.addAll(1, collect);          // Clearing the list using clear() and displaying        System.out.println("The new list is: "                           + absqlist);    }} |
Output:
AbstractSequentialList: [Geeks, for, Geeks, 10, 20] The new list is: [Geeks, A, Computer, Portal, for, Geeks, for, Geeks, 10, 20]
Example 2:
// Java code to illustrate boolean addAll()  import java.util.*;import java.util.AbstractSequentialList;  public class AbstractSequentialListDemo {    public static void main(String args[])    {          // Creating an empty AbstractSequentialList        AbstractSequentialList<Integer>            absqlist = new LinkedList<Integer>();          // Use add() method to add elements        absqlist.add(10);        absqlist.add(20);        absqlist.add(30);        absqlist.add(10);        absqlist.add(20);          // Creating a Collection        Collection<Integer>            collect = new LinkedList<Integer>();        collect.add(1);        collect.add(2);        collect.add(3);        collect.add(4);        collect.add(5);          // Displaying the list        System.out.println("The AbstractSequentialList is: "                           + absqlist);          // Appending the collection to the list        absqlist.addAll(1, collect);          // Clearing the list using clear() and displaying        System.out.println("The new list is: " + absqlist);    }} |
Output:
The AbstractSequentialList is: [10, 20, 30, 10, 20] The new list is: [10, 1, 2, 3, 4, 5, 20, 30, 10, 20]
