The removeAll() method of LinkedBlockingDeque is an in-built function is Java which is used to remove from this deque all of its elements that are contained in the specified collection. That means, all the common elements these two collections are removed from this deque.
Syntax:
public boolean removeAll(Collection c)
Parameters: This method takes collection c as a parameter containing elements to be removed from this list.
Return Value: This method returns true if this deque changed as a result of the call.
Exceptions: This method throws NULL Pointer Exception if the specified collection is Null.
Below program illustrates the removeAll() function of LinkedBlockingDeque class:
Example 1:
Java
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
LinkedBlockingDeque<Integer> LBD
= new LinkedBlockingDeque<Integer>();
LBD.add( 11 );
LBD.add( 22 );
LBD.add( 33 );
LBD.add( 44 );
System.out.println( "Linked Blocking Deque: "
+ LBD);
ArrayList<Integer> ArrLis
= new ArrayList<Integer>();
ArrLis.add( 55 );
ArrLis.add( 11 );
ArrLis.add( 23 );
ArrLis.add( 22 );
System.out.println( "ArrayList to be removed: "
+ ArrLis);
LBD.removeAll(ArrLis);
System.out.println( "Current Linked Blocking Deque: "
+ LBD);
}
}
|
Output
Linked Blocking Deque: [11, 22, 33, 44]
ArrayList to be removed: [55, 11, 23, 22]
Current Linked Blocking Deque: [33, 44]
Example 2:
Java
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
LinkedBlockingDeque<String> LBD
= new LinkedBlockingDeque<String>();
LBD.add( "geeks" );
LBD.add( "Geeks" );
LBD.add( "gfg" );
LBD.add( "Gfg" );
System.out.println( "Linked Blocking Deque: "
+ LBD);
ArrayList<String> ArrLis
= new ArrayList<String>();
ArrLis.add( "GeeksforGeeks" );
ArrLis.add( "Geeks" );
ArrLis.add( "gfg" );
ArrLis.add( "Gfg" );
System.out.println( "ArrayList: "
+ ArrLis);
LBD.removeAll(ArrLis);
System.out.println( "Linked Blocking Deque: "
+ LBD);
}
}

Output
Linked Blocking Deque: [geeks, Geeks, gfg, Gfg]
ArrayList: [GeeksforGeeks, Geeks, gfg, Gfg]
Linked Blocking Deque: [geeks]
