• Java - Problem with the classpath on Eclipse.

  - by Amokrane

  I'm trying to recompile a project I've been working on and I keep getting an error message when trying to load a property file: The system cannot find the path specified. I guess this has to do with the classpath. But I've added the path to the file in Properties- Java build path- Libraries (external class). I also checked the .classpath file generated by eclipse, and the path is really there! Why isn't Eclipse looking at the right path?

• Why Java interfaces can't have constructors?

  - by AndrejaKo

  This question showed up on my mid-term exams and I've been searching for correct answer for some time. I know that Java interfaces can't be directly instantiated so they don't need constructors and that they can have only public static final attributes so they don't need constructors to set them up but that's not the expected answer.

  - by Folkert van Heusden

  Hi, After some serious googleing I found out that the RandomAccessFile-class is not thread-safe. Now I could use one semaphore to lock all reads and writes but I don't think that performs very well. In theory it should be possible to do multiple reads and one write at a time.
