How can we implement a method performUnion() and so on that takes two sets and returns their union

One way to implement a performUnion() method in Java is to use the HashSet class, which allows for easy manipulation of sets. Here is an example of how you can create this method:

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

public class SetOperations {
    
    public static Set<Integer> performUnion(Set<Integer> set1, Set<Integer> set2) {
        Set<Integer> union = new HashSet<>(set1);
        union.addAll(set2);
        return union;
    }

    public static void main(String[] args) {
        Set<Integer> set1 = new HashSet<>();
        set1.add(1);
        set1.add(2);

        Set<Integer> set2 = new HashSet<>();
        set2.add(2);
        set2.add(3);

        System.out.println("Set 1: " + set1);
        System.out.println("Set 2: " + set2);

        Set<Integer> union = performUnion(set1, set2);
        
        System.out.println("Union of Set 1 and Set 2: " + union);
    }
}

In this implementation, we create a new HashSet called 'union' that contains all elements from both input sets. We then return this 'union' set. The main method demonstrates how to use the performUnion() method with two example sets.

This approach leverages the built-in functionality of the HashSet class in Java to easily handle operations on sets.

is this homework? because java builtin works just fine, like the AI says. adding all of set2 to set1 will result in their union
