Thread: Regarding to run a package program in java

whenever i typed a package program i get an error message "the package does not exist". so please help me to run this program

Programs in packages are required to be saved in a directory structure that matches the package structure. For example, start with s simple program, like:

package simpleprogram;
 
public class TestClass2
{
    public static void main( String[] args )
    {
        System.out.println( "In main() method." );
    }
 
}

Save the file to a subdirectory of your typical source file location called simpleprogram (the same as the package name).

Change to the directory simpleprogram and compile the source file using the command:

$ javac TestProgram2.java

(The '$ ' is a prompt, not part of the command.)

If you try and run the program while in that directory with the command java TestProgram2, you'll get an error. However, if you move up one level in the directory structure and then run the program using the command:

$ java simpleprogram/TestClass2

it will work.

If you have trouble following these directions and making it work, come back and describe exactly what you've done with any error messages you get.
