How to compile two java files in the same package

Question

This is my code in one file:

package AI;

public class Class1 {
    public static void main1() {
        System.out.println("Hello");
    }
}

And the other file:

package AI;

public class partsOfSpeech {
    public static void main(String args[]) {
        Class1 firstInstance = new Class1();
        firstInstance.main1();
    }
}

How do I compile these files, so that I don't get an error that says it can't find Class1? And how do I run them once they are compiled?

if you use command line to compile. for first compile Class1 then compile second class partsOfSpeech . but if you use IDE no problem is build automatically — Abdelhak, Nov 15 '15 at 16:32

No that didn't work it gave me: javac: file not found: AI/partsOfSpeech.java Usage: javac use -help for a list of possible options – Vityou Nov 15 '15 at 16:33

1) Go one directory above AI (e.g. D:\Study\Examples\src)

2) javac -d . AI/Class1.java

3) javac -d . AI/partsOfSpeech.java

4) java AI.partsOfSpeech

output:

Hello
