AbstractSequentialList conatinsAll() method in Java with Example Last Updated : 24 Dec, 2018 Comments Improve Suggest changes Like Article Like Report The containsAll() method of Java AbstractSequentialList is used to check whether two Collections contain the same elements or not. It takes one collection as a parameter and returns True if all of the elements of this collection is present in the other collection. Syntax: public boolean containsAll(Collection C) Parameters: The parameter C is a Collection. This parameter refers to the collection whose elements occurrence is needed to be checked in this collection. Return Value: The method returns True if this collection contains all the elements of other Collection otherwise it returns False. Below programs illustrate the AbstractSequentialList.conatinsAll() method: Program 1: Java // Java code to illustrate // AbstractSequentialList containsAll() import java.util.*; class AbstractSequentialListDemo { public static void main(String args[]) { // Creating an empty Collection AbstractSequentialList<String> abs = new LinkedList<String>(); // Use add() method to // add elements in the collection abs.add("Geeks"); abs.add("for"); abs.add("Geeks"); abs.add("10"); abs.add("20"); // prints the list System.out.println("AbstractSequentialList 1: " + abs); // Creating another empty Collection AbstractSequentialList<String> abs2 = new LinkedList<String>(); // Use add() method to // add elements in the collection abs2.add("Geeks"); abs2.add("for"); abs2.add("Geeks"); abs2.add("10"); abs2.add("20"); // prints the list System.out.println("AbstractSequentialList 2: " + abs2); // Check if the collection // contains same elements System.out.println("\nBoth the collections same: " + abs.containsAll(abs2)); } } Output: AbstractSequentialList 1: [Geeks, for, Geeks, 10, 20] AbstractSequentialList 2: [Geeks, for, Geeks, 10, 20] Both the collections same: true Program 2: Java // Java code to illustrate boolean containsAll() import java.util.*; class AbstractSequentialListDemo { public static void main(String args[]) { // Creating an empty Collection AbstractSequentialList<String> abs = new LinkedList<String>(); // Use add() method to // add elements in the collection abs.add("Geeks"); abs.add("for"); abs.add("Geeks"); // prints the list System.out.println("AbstractSequentialList 1: " + abs); // Creating another empty Collection AbstractSequentialList<String> abs2 = new LinkedList<String>(); // Use add() method to // add elements in the collection abs2.add("10"); abs2.add("20"); // prints the list System.out.println("AbstractSequentialList 2: " + abs2); // Check if the collection // contains same elements System.out.println("\nAre both collections same: " + abs.containsAll(abs2)); } } Output: AbstractSequentialList 1: [Geeks, for, Geeks] AbstractSequentialList 2: [10, 20] Are both collections same: false Comment More infoAdvertise with us Next Article AbstractSequentialList lastIndexOf() method in Java with Example C code_r Follow Improve Article Tags : Java Java-Collections Java - util package Java-Functions java-AbstractSequentialList +1 More Practice Tags : JavaJava-Collections Similar Reads AbstractSequentialList in Java with Examples The AbstractSequentialList class in Java is a part of the Java Collection Framework and implements the Collection interface and the AbstractCollection class.
