Error: Cannot find Symbol

Question

I'm not sure what my error here is saying. I did exactly what Craig explained in the video but I here is my code: 
public class Example {
  public static void main(String[] args) {
    // Your amazing code goes here...
    System.out.println("We are making a new PEZ dispenser");
    PezDispenser dispenser = new PezDispenser("Arnold Schwarchnagger");
    System.out.printf("The dispenser is %s %n", 
                       dispenser.getCharName());
    String previousHead = swapHead("T-850 Model Terminator");
    System.out.printf("Head was %s but now its %s", previousHead, dispenser.getCharName());
  }
}
class PezDispenser {
 //private String pezHead; 
  private String charaName;
  public PezDispenser(String charaName) {
   this.charaName = charaName; 
  }
  public String getCharName() {
   return charaName; 
  }
  public String swapHead(String charaName){
    String OriginalHead = this.charaName;
    this.charaName = charaName;
    return OriginalHead;
  }
}
The error I get says:
error: cannot find symbol
String previousHead = swapHead("T-850 Model Terminator");
symbol:     method swapHead(String)
location:    class Example

Hi, your swapHead method is part of your PezDispenser class, which means you have to call it on an instance of that class like this:
java
String previousHead = dispenser.swapHead("T-850 Model Terminator");

Also, you can embedd your code into your question and make it much more readable by putting three backticks (```) in front and after the code.
