    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;
    	}
     
    }

    Default Re: slick2d problem getting an error

    Exception in thread "main" java.lang.NoSuchMethodError: getPointer
    That could mean the code was compiled with a version of the class that had the getPointer() method and was executed with a version of the class that does not have that method.
    Can you check the version of the classes?
    If you don't understand my answer, don't ignore it, ask a question.
