    Default I need assistance ASAP with command "-classpath"

    Hello,
    I am not familiar with Java but I am trying to apply for a job in testting the following java application.
    I have received a tool written in Java and I need to run it with the command line:

    java -classpath ./bin com.test.Main myinputfile.txt myoutputfile.txt sort

    Main class should receive 3 parameters: inputfile, outputfile, action.

    Of course I have installed Java on my computer (Windows env.).

    The problem is that I receive this error:
    "could not find or load main class com.test.Main"

    I searched over the Internet and I saw that I need to specify the path where "Main" class is located.
    Main class is located in my c:\rachel\FileManipulator\bin\com\test

    What should I type exactly in order to run this Main class please?

    Waiting for your kindly reply, please a.s.a.p.....

    Thansk you!!! Rachel

    With the command line:
    java -classpath ./bin com.test.Main myinputfile.txt myoutputfile.txt sort
    The bin directory needs to be in the current directory
    and the com directory needs to be in the bin folder

    What was the current directory where the java command was entered?

    It'd help if you'd copy and paste here the full contents of the command prompt window.
    To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks for the fast response!

    I understand that I have to change the directory first and then run the command line I attached above.

    To which directory exactly should I change before I run this command line: to change directory to Bin or Com or FileManipulator?

    Thanks again,
    Rachel

    Change to the directory that contains the bin directory and enter:
    java -classpath ./bin com.test.Main myinputfile.txt myoutputfile.txt sort

    That directory should contain the myinputfile.txt file.
