Problem importing packages...

Question

hello!
I am learning Java for a while. I have a very strange problem with packages. The problem is the next one:
When I import the complete package like this:
import ThePackage.*
I got the following the next errors:
main.java:8: cannot resolve symbol
symbol : constructor Class1 ()
location: class Class1
Class1 C1=new Class1();
^
main.java:9: cannot resolve symbol
symbol : constructor Class2 ()
location: class Class2
Class2 C2=new Class2();
^
2 errors
In order to use this packages, I have to use it this way:
import ThePackage.Class1;
import ThePackage.Class2;
My question is if I have to import every class I am going to use per package? Or why I can�t import using asterisks ('*')
My other problem is when I use class within the same package, I have to import them too. I have to put the "import ThePackage.*;" in every class within it.
Thanks,
Santiago (A Java Newbie)

You can try to compile with javac -verbose and see what happens. It's because the class you want to compile is not in a package, and you want to import a whole package. But how would the compiler know if you want to use the Class1 and Class2 that is not in a package or those that are in a package?! First it checks if there are those classes which are not in a package. It doesn't find them, but it finds the java source code, so it attempts to use that (which will fail becuase you have package declaration in them). So sudha_mp is right about that you have to remove the source code, then you should be able to compile your code (or the class you want to compile has to be in a package).
