How do I declare an array of object references?

I need to declare an array using a class type. Cars carsArray[3]

EmployeeFactory.java:7: error: ']' expected Cars carsArray[3]; ^ EmployeeFactory.java:7: error: illegal start of expression Employee carsArray[3];

So, if I have a class called "Cars" and I want to create an array of "Cars" with 3 values in it.

Cars [] arrayName = new Cars[3];

general case

Object [] objectName = new Object[3];

Hope that helps P.S. The workspace on this video did not work for me, however, here is a link to a site with a Java emulator on it. https://www.online-java.com/. Here's the code you could paste into it just to see it run.

in Main.java

Cars [] nascar = new Cars[3];
nascar[0] = new Cars("beep");
nascar[0].honk();

in a separate Cars.java

public class Cars {
    String horn = "";
   public Cars() {
   }
   public Cars(String horn){
       this.horn = horn;
   }
   public void honk(){
       System.out.println(this.horn);
   }
}
