Compiling packages in linux

Question

Hi I have been struggling with this for the last three days. I have tried multiple searches in the forums but cannot make head nor tail of setting the classpath in linux when compiling a package.
in the following directory "/home/tamtam/Java/Course/Unit4/act4_1"
I have two classes Greeting.java and Main.java
Greeting.java compiles successfully and creates Greeting.class
I cannot compile Main.java which uses the class Greeting.
Both have package act4_1 as the first line in the code.
I know I need to set the classpath but have been unable to do so. Where is the starting directory.
I havenot got a clue where to start.
I get error message
Main.java:15: cannot resolve symbol
symbol : class Greeter
location: class act4_1.Main
Greeter greeter = new Greeter();
Any help would be greatfully appreciated.

I am completely new to Linux and just started with Java.
Does anyone know a link to a step by step guide.
in C++ say I had two files in the same directory "Greetings.cpp" and "Main.cpp" and there coresponding header files. Main.cpp uses an instance of the class Greeting. I would use include "Greeting.cpp" in Main.cpp so that the class Greeting would be available.
In Java I have two files, Greeting.java and Main.java. Both have package act4_1 at the top of the file.
Main.java
package act4_1;
     Activity 4.1
     Main.java
     Runs Greeting.java
import java.io.*;
public class Main
     public static void main(String[] args) throws IOException
          Greeter greeter = new Greeter();
          greeter.Run();
}Greeting.java
package act4_1;
     Activity 4.1
     Greeter.java.
import java.io.*;
public class Greeter {
     public void Run() throws IOException
          System.out.println("Hello from TamTam");
}How exactly do I get Main.java to accept the class Greeter.
The path is as above.
