Package--basics problem

Question

I have only just started using Java and immediately
ran into problems when trying to import a package that
I had written myself. I wrote the following minimal
programs to figure out what I am doing wrong, but I still
do not know.
1. package with method that adds two numbers.
package arithmetic;
public class Arithmetic {
   public static int addnum(int a, int b)
       return a + b;
}It compiled OK.
2. package that imports and uses addnum
package aritest;
import arithmetic.addnum;
public class Aritest {
    public static void testadd() {
       int addresult = addnum(3,2);
}It did not compile.
The output window of Sun ONE Studio 4 shows:
aritest/Aritest.java [3:1] cannot resolve symbol
symbol  : class addnum
location: package arithmetic
import arithmetic.addnum;
                  ^
aritest/Aritest.java [8:1] cannot resolve symbol
symbol  : method addnum (int,int)
location: class aritest.Aritest
       int addresult = addnum(3,2);
                       ^I am mystified by addnum being reported as a 'class' in
the first error message and as a 'method' in the second.
I also tried javac from the commandline (from a different directory).
Package arithmetic compiled OK, but aritest did not. The error
messages were slightly different from those produced by
Sun ONE Studio 4.
Would be most grateful for advice.

Answer 1

In the Aritest class, you want
import arithmetic.Arithmetic;instead of
import arithmetic.addnum;You can't import methods, only classes.
The first message is saying there's no class in the
arithmetic package called addnum. The second message
is saying it can't find a method called addnum anywhere in
the Aritest class.
