How to move a sprite with the keyboard keys using libGDX?

Question

i have just started using java and libgdx and have this code, very simply it prints a sprite onto the screen. This works perfectly, and i learnt a lot from it.

You can use the interface KeyListener to detect keyboard action.

public class Game implements ApplicationListener, KeyListener {

@Override
public void create() {
    //Important
    this.addKeyListener(this);

    // TODO Auto-generated method stub
    batch = new SpriteBatch();

    FileHandle marioFileHandle = Gdx.files.internal("mario.png"); 
    marioTexture = new Texture(marioFileHandle);
    mario = new Sprite(marioTexture, 0, 158, 32, 64);

    marioX = 0;
    marioY = 0;


}

    @Override
    public void keyPressed(KeyEvent e) {
        if (e.getKeyCode() == 68) { //it's the 'D' key
            //Move your mario
        }
    }

}
