Are these 2 packages present in the same project or in two different projects?

[Afreen Patel]

present in same project.

Well, it should work..

Perhaps there has been some conflicts by adding a new package in a project, sometimes using IDEs it happens (with Eclipse for example).
So I would suggest to rebuild the project or copy the classes in another brand new project and paste them there. (obviosuly rebuilding the package structure)

It should be working..

I am working with command prompt. I made two different packages still not working. Giving error at import statement. please help!!

[Devaka Cooray]

Can you show us the command you use to compile AnnualExam ?

[Himai Minh]

Suppose certification and university packages are in the same directory c:\myProject
Under myProject, do you use this:
java -cp certification university.AnnualExam
?

The OP is having a problem with compiling AnnualExam

Based on what the OP wrote :

I am under an impression that the code can compile, but cannot find the package during execution. Correct me if I am wrong.

To compile it, use this under c:\myProject\:
javac -cp certification university\AnnualExam.java

[Afreen Patel]

package certificate and university exist in folder myproject.


Here is the compilation steps:

[Afreen Patel]

Can you show us the value of the CLASSPATH environment variable. Does it include the C:\myproject directory ?

[Afreen Patel]

CLASSPATH
"c:\Program Files (x86)\Java\jdk1.7.0_25\bin;"

The JDK bin directory should not be in the CLASSPATH environment variable, only in the PATH environment variable. The CLASSPATH is for telling java/javac where they can find any classes they need.
Try
javac -cp C:\myproject AnnualExam.java

[Afreen Patel]

It worked

Thank you!
Thank You!!
