importing a valid package is causing a java compiler error

Question

I am getting a compiler error when compiling Order.java file even when it contains an import statement for the other packaged class. Im not entirely sure why this is happening but here is a directory tree with some files that I have:

com/my/domain/Order.java
Inside this file are the following package and imports:
```
package domain;
import utils.MyDate;
```
com/my/utils/MyDate.java
Inside this file are the following package and imports:
```
package utils;
```

Compiler error I get when compiling Order.java :

 Order.java:2: error: package com.my.utils does not exist
 import com.my.utils.MyDate;
               ^
 Order.java:5: error: cannot find symbol
  public MyDate orderDate;
       ^
  symbol:   class MyDate
  location: class Order

 Order.java:16: error: cannot find symbol
  public Order(MyDate d, double amt, String c, String p, int q){
             ^
 symbol:   class MyDate
 location: class Order

 Order.java:24: error: cannot find symbol
  public Order (MyDate d, double amt, String c) {
              ^
 symbol:   class MyDate
 location: class Order
4 errors

I am still unsure how to solve this after trying form the comments. Here is some more detail.

Existing Statements in .bash_profile :

 export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
 export CLASSPATH=${CLASSPATH}:/Users/3aCaGa/Desktop/Java-SE-8-Programs/SimplifiedDateClass/com/my

How I am trying to compile? I am going to the java file location in the directory and running command for example :

 java Order.java

For more detail on the files that and their exact contents see: https://github.com/gosem01/Java-SE-8-Programs/tree/master/SimplifiedDateClass/com/my

based upon com/my/utils/MyDate.java maybe import com.my.MyDate; — Scary Wombat

Here is my class path: export PATH=$PATH/Users/3aCaGa/Desktop/Java-SE-8-Programs/SimplifiedDateClass/com also changing it to import com.my.MyDate; got rid of the error but now I have the cannot find symbol error when I compile Order.java: Order.java:2: error: cannot find symbol import com.my.MyDate; — D-Money

1- that is not the CLASSPATH it is just the PATH; 2- it is missing the separator ':' between $PATH and /Users/... (assuming non-Windows) — user85421

and if that were the classpath, it is missing the my folder — user85421

Your package and import statements do not match your directory structure.

Your Order.class should have:

package com.my.domain;
import com.my.utils.MyDate;

and the Utils.class:

package com.my.utils;

To compile go to the directory where you can "see" the com folder and do:

*nix/MacOS

javac -cp . com/my/domain/*.java com/my/utils/*.java

Windows

javac -cp . com\my\domain\*.java com\my\utils\*.java

Hope it helps

more like javac -cp com/my/ com/my/domain/*.java com/my/utils/*.java ... or cd com/my and javac -cp . domain/*.java utils/*.java

@P.J.Meisch it is not moved anywhere just specifying the classpath using cp argument you can verify it using man javac

you're right; I mistook the cp as a shell command; sorry, just removed my previous coment
