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]
