Cant figure this one out...

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);
}

}

Error keeps referring to the following line: PezDispenser dispenser = new PezDispenser();

Any ideas?

You're supposed to have a 2nd file called PezDispenser.java that defines and implements the PezDispenser class. If you don't have it that's probably what's causing the trouble.

PezDispenser.Java

public class PezDispenser { public String mCharacterName - "Yoda"; }

The constructor for PezDispenser is supposed to be passed a String for the name of the character. You're getting that error because there is a mismatch in argument types.

OK, you're a bit earlier along than I thought. The issue is the statement:

  public String mCharacterName - "Yoda";

The minus sign should be an equals.

I fixed that but im still getting the same error message.....

public class PezDispenser { public String mCharacterName = "Yoda"; }

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);
}

}

Is the file for PezDispenser named "PezDispenser.java" or "PezDispenser.Java"? (the first is correct, the 2nd isn't)

I am getting the same error in the console. Any solutions? Both of my files are Example.java and PezDispenser.java.

Example.java code:

public class Example {

public static void main(String[] args) {
    // Your amazing code goes here...
  System.out.println("We are making a Pez Dispenser.");
  PezDispenser dispenser = new PezDispenser();
  System.out.printf("The dispenser character is %s\n",
                    dispenser.mcharacterName);  

}

}

PezDispenser.java code:

public class Example { public String mcharacterName = "Yoda"; }

Console error:

./PezDispenser.java:1: error: class Example is public, should be declared in a file named Example.java
public class Example {
^
Example.java:6: error: cannot access PezDispenser
PezDispenser dispenser = new PezDispenser();
^
bad source file: ./PezDispenser.java
file does not contain class PezDispenser
Please remove or make sure it appears in the correct subdirectory of the sourcepath.

yep, you have to put public before class PezDispenser {}
