these are my 3 files codes

Game.java

package javagame;
 
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
 
public class Game extends StateBasedGame {
 
	public static final String gamename = "Ham Blaster!";
	public static final int menu = 0;
	public static final int play = 1;
 
	public Game(String gamename) {
		super(gamename);
		this.addState(new Menu(menu));
		this.addState(new Play(play));
	}
 
	public void initStatesList(GameContainer gc) throws SlickException {
		this.getState(menu).init(gc, this);
		this.getState(play).init(gc, this);
		this.enterState(menu);
	}
 
	public static void main(String[] args) {
		AppGameContainer appgc;
		try {
			appgc = new AppGameContainer(new Game(gamename));
			appgc.setDisplayMode(640, 360, false);
			appgc.start();
		}catch(SlickException e) {
			e.printStackTrace();
		}
	}
 
}

Menu.java

package javagame;
 
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
 
public class Menu extends BasicGameState {
 
	public Menu(int state) {
	}
 
	public void init(GameContainer gc, StateBasedGame sbg) throws SlickException {
	}
 
	public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException {
	}
 
	public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException {
	}
 
	public int getID() {
		return 0;
	}
 
}

Play.java

package javagame;
 
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
 
public class Play extends BasicGameState {
 
	public Play(int state) {
	}
 
	public void init(GameContainer gc, StateBasedGame sbg) throws SlickException {
	}
 
	public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException {
	}
 
	public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException {
	}
 
	public int getID() {
		return 1;
	}
 
}
