Using scanner and if/else statement to draw one of two graphics.

Hey there, I have a homework problem for us to solve. I have to make a program for my introductory programming course that displays either one picture (a "wild face") or another (a "happy face") when the user inputs their response to the question("Are you feeling happy or wild?"). The problem is that I don't know how to make the if/else statement display the appropriate graphics on screen. Here's my code so far:

import javax.swing.JApplet;
import java.awt.Color;
import java.awt.Graphics;
import java.util.Scanner;

public class HappyWild{
	
	public void init() {
		setSize(1000,1000);
	}
		
	public void wildFace (Graphics canvas)
	{
		//Draw outline
		canvas.setColor(new Color(237,207,159));
		canvas.fillOval(100, 50, 200, 200);
		canvas.setColor(Color.BLACK);
		canvas.drawOval (100, 50, 200, 200);
		
		//Draw eyebrows
		canvas.fillRoundRect(150, 80, 40, 10, 8, 16);
		canvas.fillRoundRect(215, 80, 40, 10, 8, 16);
		
		//Draw mustache
		canvas.drawLine (190, 184, 150, 195);
		canvas.drawLine (210, 184, 250, 195);
		
		//Draw lips
		canvas.drawArc (163, 190, 32, 20, 360, 180);
		canvas.drawArc (195, 190, 32, 20, 360, 180);
		
		//Draw eyelids
		canvas.setColor(Color.BLACK);
		canvas.drawArc (150, 95, 40, 20, 360, 180);
		canvas.drawArc (215, 95, 40, 20, 360, 180);
		
		//Draw nose
		canvas.drawLine (200, 125, 200, 165);
		canvas.drawArc (192, 175, 16, 4, 180, 180);
		canvas.drawArc (208, 170, 8, 4, 90, 180);
		canvas.drawArc (184, 170, 8, 4, 99, -180);
		
		//Draw mouth
		canvas.drawLine (163, 200, 228, 200);
				
		//Draw eyes
		canvas.setColor(Color.WHITE);
		canvas.fillOval (155, 100, 25, 20);
		canvas.fillOval (220, 100, 25, 20);
		canvas.setColor(Color.BLACK);
		canvas.drawOval (155, 100, 25, 20);
		canvas.drawOval (220, 100, 25, 20);
		
		//Draw irises
		canvas.setColor(new Color(158,104,17));
		canvas.fillOval (163, 107, 10, 10);
		canvas.fillOval (228, 107, 10, 10);
				
		//Draw pupils
		canvas.setColor(Color.BLACK);
		canvas.fillOval (165, 109, 6, 6);
		canvas.fillOval (230, 109, 6, 6);
				
		//Draw eye shine
		canvas.setColor(Color.WHITE);
		canvas.fillOval (168, 109, 2, 2);
		canvas.fillOval (233, 109, 2, 2);
		
	}
	
	public void happyFace (Graphics canvas)
	{
		// Draw outline
        canvas.drawOval (100, 50, 200, 200);

        // Draw eyes
        canvas.fillOval (155, 100, 10, 20);
        canvas.fillOval (230, 100, 10, 20);

        // Draw mouth
        canvas.drawArc (150, 160, 100, 50, 180, 180);
	}
	
	public static void main(String[] args) {
		System.out.println("Are you feeling happy or wild?");
		System.out.println("Type in either 'happy' or 'wild'.");
		Scanner keyboard = new Scanner(System.in);
		String answer = keyboard.next();
		System.out.println("You entered: \"" + answer + "\"");
		if (answer.equalsIgnoreCase("happy"))
			happyFace (Graphics canvas);
		else if (answer.equalsIgnoreCase("wild")) 
			wildFace (Graphics canvas);
		else 
			System.out.println("incorrect input.");
			
	}
}

Eclipse keeps telling me to delete the token "canvas" and that Graphics cannot be resolved to a variable, whatever those two statements mean. Thanks for your time and any help.
