linux to compile multiple java file

Question

here is my directory structure.

/user/a /user/b /user/b

inside folder a,b,c there is a file person.java (it is the Same file, just a one line modification.

now, on my shell, im on my /user/ directory and i try to do

   javac */person.java

the shell returns the following error,

person.java:14: duplicate class: person

Is there anything to resolve this?

Answer 1

I think the problem here might be, that javac tries to compile everything in one go, which naturally results in duplicated class definitions.

A simple way to resolve this would be

find . -name '*.java' -exec javac {} \;

Edit:

Or to be more precise find . -name 'person.java' -maxdepth 2 -exec javac {} \;

Answer 2

I would go for the small shell script:

for f in */person.java; do
  javac $file
done

First line find all the files person.java in a sub-directory, second line compile the file.
