The remove(Object O) method of Java AbstractCollection is to remove a particular element from a Collection.
Syntax:
AbstractCollection.remove(Object O)
Parameters: The parameter O is of the type of Collection and specifies the element to be removed from the collection.
Return Value: This method returns True if the element specified in the parameter is initially present in the collection and is successfully removed otherwise it returns False.
Below program illustrate the Java.util.AbstractCollection.remove() method:
Program 1:
// Java code to illustrate remove()  import java.util.*;import java.util.AbstractCollection;  public class AbstractCollectionDemo {    public static void main(String args[])    {          // Creating an empty AbstractCollection        AbstractCollection<String>            abs = new TreeSet<String>();          // Use add() method to add        // elements into the Collection        abs.add("Welcome");        abs.add("To");        abs.add("Geeks");        abs.add("4");        abs.add("Geeks");        abs.add("TreeSet");          // Displaying the Collection        System.out.println("Collection: " + abs);          // Removing elements using remove() method        abs.remove("Geeks");        abs.remove("4");        abs.remove("TreeSet");          // Displaying the Collection after removal        System.out.println("New Collection: " + abs);    }} |
Output:
Collection: [4, Geeks, To, TreeSet, Welcome] New Collection: [To, Welcome]
Program 2:
// Java code to illustrate remove()  import java.util.*;import java.util.AbstractCollection;  public class AbstractCollectionDemo {    public static void main(String args[])    {          // Creating an empty AbstractCollection        AbstractCollection<String>            abs = new LinkedList<String>();          // Use add() method to add        // elements into the Collection        abs.add("Welcome");        abs.add("To");        abs.add("Geeks");        abs.add("4");        abs.add("Geeks");        abs.add("LinkedList");          // Displaying the Collection        System.out.println("Collection: " + abs);          // Removing elements using remove() method        abs.remove("Geeks");        abs.remove("4");        abs.remove("LinkedList");          // Displaying the Collection after removal        System.out.println("New Collection: " + abs);    }} |
Output:
Collection: [Welcome, To, Geeks, 4, Geeks, LinkedList] New Collection: [Welcome, To, Geeks]
