Explanation / Answer

/*
copy this code into a new file and save as FaceFrame.java
Compile and execute it
*/
import java.awt.Color;

import java.awt.Graphics;

import java.util.ArrayList;

import javax.swing.JPanel;

import javax.swing.*;

//FaceFrame class

/*

You have to import import javax.swing.*; in FaceFrame.java

And You have implemented FaceDraw class and called Face()

and main function should be public else it gives main method not found

I just changed FaceDraw with Face

and it have compiled correctly

You have posted that it is not compiling now it is compiling correctly
