Use the Sets and Maps Mathematics Review to understand basic set operations. Go over the practice problem provided under this module titled Sets and Maps Practice. You may use the Sets and Maps Starter Solution to help you solve the following operations using Java set operations.

Solve the following Set Operations using Java code as shown on the sample Sets and Maps Starter Solution.

1)A

2) B

3)

4)

5)

6)

7)

8)

9)

10)

Here is the practice:

import java.util.*;

public class SetsPractice {

public static void main(String[] args) {

// Create two linked hash sets

Set set1 = new LinkedHashSet<>(Arrays.asList(

"George", "Jim", "John", "Blake", "Kevin", "Michael"));

Set set2 = new LinkedHashSet<>(Arrays.asList(

"George", "Katie", "Kevin", "Michelle", "Ryan"));

// Display the union of the two sets

Set union = new LinkedHashSet<>(set1);

union.addAll(set2);

System.out.println("Union of the two sets: " + union);

// Display the difference of the two sets

Set difference = new LinkedHashSet<>(set1);

difference.removeAll(set2);

System.out.println("Difference of the two sets: " + difference);

// Display the intersetion of the two sets

Set intersection = new LinkedHashSet<>();

for (String e: set2) {

if (set1.contains(e))

intersection.add(e);

}

System.out.println("Intersection of the two sets: " + intersection);

}

}

and here is the solution we were given:

import java.util.*;

public class Solution {

public static void main(String[] args)

{

// Create two linked hash sets

Set universe = new LinkedHashSet<>(Arrays.asList("a", "b", "c", "d", "e"));

Set set1 = new LinkedHashSet<>(Arrays.asList("c", "d", "e"));

Set set2 = new LinkedHashSet<>(Arrays.asList("a", "c", "d"));

// Display the union of the two sets

Set union = new LinkedHashSet<>(set1);

union.addAll(set2);

System.out.println("2. Union of the two sets: " + union);

// Display the difference of the two sets

Set difference = new LinkedHashSet<>(set1);

difference.removeAll(set2);

System.out.println("Difference of the two sets: " + difference);

// Display the intersetion of the two sets

Set intersection = new LinkedHashSet<>();

for (String e: set2) {

if (set1.contains(e))

intersection.add(e);

}

System.out.println("3. Intersection of the two sets: " + intersection);

Set compliment = new LinkedHashSet<>(universe);

compliment.removeAll(set1);

System.out.println("1. Compliment of set A: " + compliment);

}

}
