How to set font size in Slick 2D

#1

I tried doing this to change the font size of my intro, but I am getting an error of "the method setFont() in the type Graphics is not applicable for the arguments (Font) "

Here is what I’ve tried:

import java.awt.Font;

import org.lwjgl.input.Mouse;
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;

public class FirstGameMenu extends BasicGameState{
	
	Font font;
	
	public FirstGameMenu(int state){
		
	}
	
	// load all fonts, graphics, sounds, etc
	public void init(GameContainer gc, StateBasedGame sbg) throws SlickException{
		font = new Font("Time New Roman", Font.BOLD, 20);
	}

	//draw stuff on the screen
	public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException{
		
		Image enter = new Image("res1/button2.png");
		//set the coordinates for the pic
		g.drawImage(enter, 315, 180);
		g.setFont(font);
		g.drawString("How to Play", 385, 460);
		g.drawString("Exit", 415, 520);	
	}
