Thread: Importing library for server

I need help compiling and running my programs using the command-line prompt or on my desktop rather than using an IDE. Specifically I do not know how to make my import statements work in my programs without my IDE while I have moved my library now which is a folder containing additional .java files to my Downloads directory. For example my programs, three of them are in Downloads and in this folder I have my library as a folder which is named socklib and I wish to convert the following statements in order to have no resulting errors:

//Program 1: GreeterClientExample.java
package com.school.course.example;
import com.school.course.socklib.ClientProtocolFactory;
import com.school.course.socklib.ClientSocket;
import java.util.Scanner;

//Program 2: GreeterServerExample.java
package com.school.course.example;
import com.school.course.socklib.ServerListener;
import java.util.Scanner;

//Program 3: GreeterServerProtocol.java
package com.school.course.example;
import com.school.course.socklib.ListenerInfo;
import com.school.course.socklib.SimpleSocketProtocol;
import java.io.IOException;
import java.net.Socket;

I read online there are many different types of imports in Java such as <library> or using / instead . and I am not sure how to make this work or what my path should be either. If anyone is able to help me with this, my directory structure is /Users/user/Downloads/...

It has to be in separate directories. IDE is preferred because all your programs which is integrated in the websites can work on separate directories and editors. As for putting this on another web page like a button to place on, that's done by exporting the files to the right URL. Using two different pc for the programming.
