Error in U4L5, 6D

In lesson U4L5, level 6D, the directions on lines 17-35 of do not make sense. I pasted them below. First of all, the —TO DO— is inside of the wrong method. That method, getImages(), is incomplete, but all the directions say to write the code for chooseRandomImage(). However, chooseRandomImage() is written correctly and doesn’t need any changes. Finally, getImages() is not necessary for the program to function, but it needs to correctly return a String array for the code to compile. Once I fix the return statement in that method, the code passes all the tests even though I only had to add a single word, the name of the instance variable (images), to the return statement on line 26. I don’t think meant to write the level so that I only needed to add a single word to the wrong method to make the code work.


  • Returns the 1D array of images
    public String[] getImages() {
    ----------------------------------- TO DO -----------------------------------
    • :white_check_mark: Return a random image from the images array.

return "";



  • Returns a random image from the 1D array of images
    public String chooseRandomImage() {
    int randomIndex = (int)(Math.random() * images.length);
    return images[randomIndex];
