    Default cmd java run issue

    When I compile my java application in NetBeans there's no problem but when I try to run my application through the command prompt I get the following error:

    The class cannot be found. It looks like your class is a member of a package - be sure you are executing relative to the root of the package. See

    I was used javac CarInsuranceCalc.java

    Then java CarInsuranceCalc

    I just tried java pkgCarInsuranceCalc.CarInsuranceCalc

    Now I'm receiving the following:

    Error: Could not find or load main class pkgCarInsuranceCalc.CarInsuranceCalc.class

    (Actually doesn't matter tried the latest command in the src folder and it worked).
