This code doesn't work

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 = null; return teachers; }

}

TeachersExample.java
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 = new String[3];
    teachers[0] = "Jay";
    teachers[1] = "Dave";
    teachers[2] = "James";
    return teachers;
  }

}

The challenge instructions say "Your task is to create the array in a shorter literal form", but the code shown here is just a duplicate of the long form that was provided for reference. Your job is to do it in a different, more compact way.

Hint: the proper solution will comfortably fit on one single line.
