Need Help in compiling package

[Wasim Ahmed]

Anyone tried to compile KHM Book ex #4.8. I am getting compiling error in package B "package A not found" but it is in same directory. I am using JDK 1.3 and jcreator. Any suggestion
:confused

Hi Wasim,
I don't have a copy of the code but if by 'it is in the same directory' you mean the compiled class file is in the same directory as the class marked package B you will get a compile error.
If you have two source files, one marked 'package A;' and another marked 'package B' your directory set up should be

root dir
     subdir A
         source file 'A.java' with 'package A' statement
     subdir B
         source file 'B.java' with 'package B' statement

You then need to compile from the 'root' directory using

javac A\A.java
javac B\B.java

Java expects the package naming to follow the directory structure. 'package A' instructs the compiler to look for the source file in the 'A' subdirectory. 'package B' instructs the compiler to look for the source file in the 'B' subdirectory. It searches for the subdirectories in the current directory.
Hope that helps.
