## SetEqual
### Instructions
Create a file `SetEqual.java`.
Write a function `areSetEquals` that returns `true` if the sets as parameters are equal. Returns `false` otherwise.
### Expected Functions
```java
import java.util.Set;
public class SetEqual {
public static boolean areSetEquals(Set<String> set1, Set<String> set2) {
// your code here
}
}
```
### Usage
Here is a possible ExerciseRunner.java to test your function:
```java
import java.util.HashSet;
import java.util.Set;
import java.util.TreeSet;
public class ExerciseRunner {
public static void main(String[] args) {
Set<String> set1 = new TreeSet<>();
set1.add("Alice");
set1.add("Bob");
set1.add("Charly");
Set<String> set2 = new TreeSet<>();
set2.add("Bob");
set2.add("Charly");
set2.add("Alice");
System.out.println(SetEqual.areSetEquals(set1, set2)); // Expected Output: true
Set<String> set3 = new HashSet<>();
set3.add("Alice");
set3.add("Bob");
set3.add("Charly");
Set<String> set4 = new HashSet<>();
set4.add("Alice");
set4.add("Bob");
set4.add("Emily");
System.out.println(SetEqual.areSetEquals(set3, set4)); // Expected Output: false
}
}
```
and its output :
```shell
$ javac *.java -d build
$ java -cp build ExerciseRunner
true
false
$
```
