Question

The classes belong to the same pkg. They are in the dir, name of the pkg.

• In general, how can classes access one another in the same pkg?

Error

javac PackTest.java
PackTest.java:8: cannot find symbol
symbol  : class PriTest
location: class pacc.PackTest
  System.out.println(new PriTest().getSaluto());
                         ^
1 error

Classes in the PKG pacc

$ cat PackTest.java 
package pacc;
import java.io.*;

public class PackTest
{
    public static void main(String[] args)
    {
        System.out.println(new PriTest().getSaluto());
    }
}
$ cat PriTest.java 
package pacc;

public class PriTest
{
    public PriTest(){}
    private String saluto="SALUTO FROM PriTest";
    public String getSaluto(){return saluto;}
}

PKG of the name of dir

$  find .. -type d -name "pacc"
../pacc
$ ls ../pacc 
makefile  PackTest.java  PriTest.java
$ ls
makefile  PackTest.java  PriTest.java

Solved!

$ cat makefile 
p:
    javac ./pacc/PackTest.java
    java pacc/PackTest
$ make p
javac ./pacc/PackTest.java
java pacc/PackTest
SALUTO FROM PriTest

Answer 1

MAYBE (So don’t kill me, please) this is a solution:

In the terminal, go to the root of your java project (so the default package, in your situation, the parent directory of the folder pacc).
Then type: javac pacc.PackTest.java

I don’t use the compiler manually. My IDE does that work for me.
