Having issues with Importing packages

Question

Hi
Can someone help me with the behaviour i am noticing with jdk1.3.1
Say i have a directory by name test in c:\
so i have c:\test
say i have Add.java Test.java files in it.
The contents of these files are as follows
/** Add.java file */
package mypackage;
public class Add
public Add() { }
/** Test.java */
import mypackage.*;
public class Test
public Test() { }
public static void main(String[] args)
Add testAdd = new Add();
Now being in c:\test directory i perform the following steps
javac -d . Add.java
It compiles fine and it created a directory called mypackage within c:\test. thus i have
Add.class file in c:\test\mypackage directory
Then i did
javac Test.java
Now i get compiler errors saying
Test.java:8 : cannot resolve symbol
symbol : constructor Add ()
location: class Add
Add testAdd = new Add();
^
1 error
Pls help
Thanks

I'm not smart enough to answer why. My guess: the compiler always looks around for .java files that it might need to compile. Most of the time, this is a good thing because the compiler will automatically compile .java files instead of the user typing in all files. In your case, it appears that the compiler looks for a class named Add and finds the Add.java file before it looks thru the mypackage import so it tries to compile the file. The file contains mypackage.Add instead of a no package Add class so you get an error.
