You're creating the array literal properly, it's just in the wrong place. On line 13, inside the getTeachersAsArrayLiteral method, it wants you to replace null with the array literal right here. It doesn't want you to add new methods.

public class TeachersExample {

  public String[] getTeachersInArrayLongForm() {
    String[] teachers = new String[3];
    teachers[0] = "Jay";
    teachers[1] = "Dave";
    teachers[2] = "James";
    return teachers;
  }

  public String[] getTeachersAsArrayLiteral() {
    // TODO: Replace null with an array literal that matches the long form above
    String[] teachers = {"Jay", "Dave", "James"};
    return teachers;
  }

}

You just need to do this in getTeachersAsArrayLiteral() method ===> String[] teachers = getTeachersInArrayLongForm(); because getTeachersInArrayLongForm is method that returns already populated array
