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]
