Abstract collection contains All() method in Java, example
Abstract collection contains the All() method in Java, example Original text: https://www . geesforgeks . org/abstract collection-contains all-in-Java-method-in- with-examples/ Java Abstract Collection‘s containsAll() method is used to check whether two collections contain the same elements. It takes a collection as argument and returns True if all elements of the collection are present in the other collection. Syntax: AbstractCollection.containsAll(Collection C) Parameter:ParameterC is a collection. This parameter refers to the collection whose elements need to be checked for occurrence in this collection. Return value: If this set contains all elements of other sets, this method returns true, otherwise it returns false. The following program illustrates the AbstractCollection.conatinsAll() method: Program 1: // Java code to illustrate boolean containsAll()import java .util.*;class AbstractCollectionDemo { public static void main(String args[]) { // Creating an empty Collection AbstractCollection< 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”); // Creating another empty Collection AbstractCollection< String> = 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”); // Check if the collection // contains same elements System.out.println(“\nBoth the collections same: ” .containsAll(abs2)); }} Output: Both the collections same: true Program 2: // Java code to illustrate boolean containsAll()import java.util.*;class AbstractCollectionDemo { public static void main(String…

AtomicLongArraygetAndSet() method in Java, example
AtomicLongArray getAndSet() method in Java, examples Original text: https://www . geeksforgeeks . org/atomicongarray-getandset-method-in-Java-with-examples/ Java . util . concurrent . atomic . AtomicLongArray . getandset() is a built-in method in Java that automatically sets a given value at any given position in an atomicongarray . This method takes as parameters the index value of the atomic clone array and the value to be set. It returns the value at the given index and then sets the new value at that index. The function getAndSet() is similar to the set() function, but the former returns a value while the latter does not. Syntax: Public final long getAndSet(int i, long newValue) Parameters:This function accepts two parameters: I–the index to be updated. newValue – The value to set at index i* Return value:This function returns the value at the given index before updating The value is in Long. The following program illustrates the above method: Program 1: “`java// Java program that// the getAndSet() function import demonstrates java.util.concurrent.atomic.AtomicLongArray; public class GFG { public static void main(String args[]) a AtomicLongArray arr = new AtomicLongArray(a); // Displaying the AtomicLongArray System.out.println(“The array : ” + arr); // Index where operation is performed int idx = 0; // New…
