Added the isEmpty() function which returns mPezCount == 0; now getting this error: "java.util.NoSuchElementException"

So I added the following to my PezDispenser.java

 public boolean isEmpty() {
  return mPezCount == 0;
  }

Now when I run the following command in the repl:

PezDispenser pd = new PezDispenser("Yoda");

I get this error:

java.util.NoSuchElementException

What have I done wrong? My PezDispenser.java looks the same as the teacher's...

I'll answer this myself. I actually had a tiny 'fullstop' in my PezDispenser.java in one of the lines that was throwing the exception. After scanning the file carefully and removing it, and loading it again, it compiled without any issues.

public class PezDispenser {

public String mCharacterName;

public PezDispenser (String characterName) { mCharacterName = characterName; mCountPez = 0;

}

public boolean isEmpty() {

return mCountPez == 0; } pulbic void load() { mPezCount = MAX_PEZ; }

public static final int MAX_PEZ = 12; public int mPezCount;

public String getCharacterName() { return mCharacterName; }

}
