Convert File[] to String[] in Java

Question

i have this code

File folder = new File("F:\\gals");
File[] listOfFiles = folder.listFiles();  

this code returns an array of locations of all files in folder F:\gals , and i tried to use this location in selenium code

driver.findElement(By.id(id1)).sendKeys(listOfFiles[1]);

and i see errors

The method sendKeys(CharSequence...) in the type WebElement is not applicable for the arguments (File)

so i think i have to convert listOfFiles[] to String array, plz tell me simple way to do this. Thanks

Answer 1

You don't need to convert the whole array. Just call File's getAbsolutePath() method:

driver.findElement(By.id(id1)).sendKeys(listOfFiles[1].getAbsolutePath());

But if you do want to convert the whole array, here is the Java 8 way to do this (simplified by @RemigiusStalder):

String listOfPaths[] = Arrays.stream(listOfFiles).map(File::getAbsolutePath)
        .toArray(String[]::new);

Answer 2

Just call File.list() instead.
