Unless the other class is in a specific package, then you don't need to import anything (it will be in the default package). Maybe if you post your code (and use the [java] tags!), we can offer more specific help...

The other class needs to be in your CLASSPATH.
You may eed to consult the documentation for your particular java development kit installation and modify your CLASSPATH.

Or when you compile you can add the other classpath inside the javac command

if your other class is at:
C:\j2sdk1.4.0\projects\MyOtherClass.class
then you can add this into to the javac compile statement with

javac -classpath %CLASSPATH%;C:\j2sdk1.4.0\projects\MyOtherClass.class ThisClass.java
