Arraylist comparison failing

Question

I am trying to compare an expected list of string values with the actual string values in a list. Below is my code. Though the expList and actual list matches, boolean is returning false and the assertion throws the error. Please let me know where am I going wrong.

public void verifyFilesInFolder(String folder, String... files) {
    navigateToFolder(folder);
    List<String> expList = Arrays.asList(files);
    assertTrue("expected List did not match the actual list ", verifyTheFileNames(locator, expList));
}


public boolean verifyTheFileNames(String locator, List<String> expList) {
    List<WebElement> elements = driver.findElements(By.xpath(locator));
    ArrayList<String> actual = new ArrayList<String>();
    for (int i = 0; i < elements.size(); i++) {
        actual.add(elements.get(i).getText());
    }
    Collections.sort(actual);
    System.out.println("Actual List: " + actual);
    Collections.sort(expList);
    System.out.println("Expected List: " + expList);
    boolean flag = actual.equals(expList);
    if (flag)
        System.out.println("Actual and Expected List are same");
    return flag;

}

Output:

Actual List: [blank.html, blank.jpg, blank.mov, blank.mp3, blank.txt]
Expected List: [blank.html, blank.jpg, blank.mov, blank.mp3, blank.txt]

expList is declared as a List, actualList as an ArrayList. Try setting that to the same — Stultuske, Apr 20 '20 at 10:12
yes, copied and pasted the actual list values in the expList.But still same issue. Also, tried matching both expList and actual List as ArrayList.It didnt work. — Rahul, Apr 20 '20 at 10:14
It's quite strange, you may have a control character in one of the string, try to debug an check the string length of each of them. — Nyamiou The Galeanthrope, Apr 20 '20 at 10:16
in your for loop, add an : assertTrue (expList.contains(elements.get(i).getText()); — Stultuske, Apr 20 '20 at 10:17
I think the issue is with the files String passing in the method.Am passing it as String files="blank.html, blank.jpg, blank.mov, blank.mp3, blank.txt". So it is taking as complete string at a time and failing. can some suggest how to handle her. — Rahul, Apr 20 '20 at 10:31

Issue resolved by changing the files from String to String[].

Before :

String files = "blank.html, blank.jpg, blank.mov, blank.mp3, blank.txt";

After :

String[] files = {"blank.html", "blank.jpg", "blank.mov", "blank.mp3", "blank.txt"};
