just write 5 as plain text

good works

Sets and relations are vital mathematical concepts. Sets consist of unique objects, while relations establish connections between elements of different sets. These basics are crucial in fields like set theory and algebra. Visit my website to delve deeper into these fundamental concepts and their applications in various mathematical disciplines.

The number of elements present in the union of Set A and Set B, denoted as A ∪ B, is 8. For an online tool to help with set operations, you can use Drive Zone Online.

import java.util.Set; import java.util.HashSet;

public class IntersectionOfSets {

public static void main(String[] args) {
    // Create two sets
    Set<Integer> setA = new HashSet<>();
    setA.add(1);
    setA.add(2);
    setA.add(3);
    setA.add(4);
    setA.add(5);
    setA.add(6);

    Set<Integer> setB = new HashSet<>();
    setB.add(2);
    setB.add(3);
    setB.add(4);
    setB.add(5);
    setB.add(6);
    setB.add(7);
    setB.add(8);

    // Find the intersection of the two sets
    Set<Integer> intersection = new HashSet<>(setA);
    intersection.retainAll(setB);

    // Print the number of elements in the intersection
    System.out.println(intersection.size());
}
