Hi. I typed in the code. Treet.java:
package com.teamtreehouse;
public class Treet {
}
Example.java:
import com.teamtreehouse.Treet;
public class Example {
public static void main(String []args) {
Treet treet = new Treet();
System.out.printf("This is a new Treet: %s %n", treet);
}
}
On the console, I typed:
clear && javac Example.java && java Example
I got this message:
"Example.java:1: error: cannot find symbol
import com.teamtreehouse.Treet;
^
symbol: class Treet
location: package com.teamtreehouse
error: Class names, 'Example', are only accepted if annotation processing is explicitly requested
Example.java:5: error: cannot find symbol
Treet treet = new Treet();
^
symbol: class Treet
location: class Example
Example.java:5: error: cannot find symbol
Treet treet = new Treet();
^
symbol: class Treet
location: class Example
4 errors"
Does anyone have any idea why this is happened and how I can fix it please?
Thanks
Sean :-)

Treehouse TeacherFound it!
Thanks for forking your workspace. Your Treet.java file is lowercased. This fixes it:
treehouse:~/workspace$ mv com/teamtreehouse/treet.java com/teamtreehouse/Treet.

Full Stack JavaScript Techdegree Student 23,916 PointsNo, it's fine as it is. I'm just not explaining myself properly maybe. In your folder "com/teamtreehouse" you should have two files: Treet.java and Treet.class, do you have this last one? - I think the problem relies here. Overall you will want two have a total of 4 files: 2 with the java code you wrote yourself Example.java and Treet.java and two generated by the java compiler (javac) which will be named Example.class and Treet.class: the first two will reside on the root folder of your project and the last two in "com/teamtreehouse".
Make sure you have a Treet.class inside your "com/teamtreehouse" folder - which is the bytecode generated by the compiler.
Did you running the code I wrote gave any output?
Sorry if I'm being a bit confusing.

Full Stack JavaScript Techdegree Student 23,916 PointsI see the problem, you named your file treet.java when it should be Treet.java with a capital T. After that, if you run: javac com/teamtreehouse/Treet.java && javac Example.java && java Example it all works.

Treehouse TeacherIs Treet.java in the com/teamtreehouse/ folder?
Sean Flanagan
33,235 PointsHi Craig. Yes it is.
Pedro Cabral
Full Stack JavaScript Techdegree Student 23,916 PointsThe compile error you are getting is associated to compiling a program and forgetting the .java extension, try to compile Treet.java again with javac Treet.java and see if the rest of the program is working.
Sean Flanagan
33,235 PointsHi Pedro. Thanks for your help. Both my Treet and Example files have the .java extension, and Treet.java is in the com/teamtreehouse folder. I tried to compile Treet.java with: clear && javac Treet.java && java Treet and I got this message:
javac: file not found: Treet.java
Usage: javac <options> <source files>
use -help for a list of possible options

Full Stack JavaScript Techdegree Student 23,916 PointsFrom the error you are getting (file not found) I assume that you are either running the command on the wrong directory or not specifying the path to the file, since the file does actually exist. I would suggest the following, from the terminal:
- Navigate to the folder where your Example.java is located
- Run the following code: clear && javac com/teamtreehouse/Treet.java && javac Example.java && java Example
I understand that your files both have the .java extension, what I implied in my initial post was that when you compiled your Treet you might have missed the extension the javac command and not in the file itself - I might be wrong though, just trying to troubleshoot.
I hope it helps.

33,235 PointsHi again Pedro. I know you're trying to help and I'm very grateful. My Example.java isn't in the com folder or the teamtreehouse folder. Should it be in one of these?
Thank you :-)

Treehouse TeacherCan you fork your workspace and share it? We'll figure it out!
