What is the output of the following Java program? – Selenium and Java Challenge 1

I have started a 30-day Selenium with Java challenge to help beginners and intermediate software testers for learning Selenium and Java concepts. This is first challenge. Share your answers in the comments about the program’s output—I’ll provide my short answer afterward.

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import org.testng.annotations.Test;

public class SampleProgram1 {

@Test
public void testMySkills() {
    System.out.println(getListItem());
}

public int getListItem() {
    List<Integer> list = new ArrayList<>();
    list.add(8);
    list.add(9);
    list.add(6);

    int i = 0;
    for (int num : list) {
        list.set(i, num + 10);
        i++;
    }

    Collections.sort(list);
    return list.get(0);
}

}
