Getting two errors while compiling and I am not sure why. Syntax seems correct.

So far I have 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();
    System.out.printf("The dispenser character is %s/n",
                        dispenser.mCharacterName);
}

}

which as far as I know should be working. The concepts here make sense, but I am getting a compiler error along the PezDispenser dispenser = new PezDispenser(); indicating a symbol not found on "PezDispenser" and "PezDispenser();"

if anyone could explain this to me that would be great.

Could you add your PezDispenser class as well. You main method looks right.

Answer: I am dumb and capitalized the file extension (PezDispenser.Java as opposed to PezDispenser.java)

Hello

I believe your error is here:

ystem.out.printf("The dispenser character is %s/n", dispenser.mCharacterName);

mCharacterName is generally a private attribute in a Class. To get ti it, you should be using a getter method instead. Please double check you class and use a gerrter method. It should be something like

dispenser.getCharacterName()

if this answers your question, please mark the question as answered.

Thanks

I made this change in the document and it did not solve the issue.

As far as I can tell my syntax matches everything in the video and I am still getting compiler errors of "cannot find symbol". That line is also not indicated as an error line, and the video does make use of dispenser.mCharacterName and not dispenser.getCharacterName(). The errors come before that as well, so that seems to be unrelated.

note that this is the first exercise and this should work using mCharacterName

Alright, this is yet solved perfectly though I did work around it (with help from a friend) by adding the PezDispenser class directly to Example in one document, and also made PezDispenser static.

{

static class PezDispenser { private String mCharacterName;

public PezDispenser(String characterName){
      mCharacterName = characterName;
}

public String getCharacterName(){
    return mCharacterName;
}

} }

I am yet unsure why this doesn't work in the workspace across two files.
