How to name an Actor in libgdx?

Actors have no names below. In libgdx whats the best way assign a name to each actor?

public class JewelsMainActivity implements ApplicationListener, InputProcessor {

private Vector2 point = new Vector2();
public TextureAtlas jewelsAtlas;
public Texture jewels;
private SpriteBatch batch;  
public Actor[][] actors = new Actor[10][10];
public Stage stage;
public int gridSize;

@Override
public void create() {
    stage = new Stage(800, 600, false);
    gridSize = 10;
    batch = new SpriteBatch();
    jewels = new Texture(Gdx.files.internal("assets/gems1.png"));
    jewelsAtlas = new TextureAtlas(Gdx.files.internal("assets/pack"));
    for (int z = 0; z < gridSize; z++) {
        for (int x = 0; x < gridSize; x++) {
                Random r = new Random();
                int j = r.nextInt(2)+1;
                actors[x][z] = new Image(jewelsAtlas.findRegion(""+j+""));
                actors[x][z].x = x*56; //each gem is 56*56 width / height
                actors[x][z].y = z*56;

// actors[x][z].name = "actor"+x+z; // cant use this above as it wont allow....

                stage.addActor(actors[x][z]);

        }
    }
    Gdx.input.setInputProcessor(this);
}


@Override
public void render() {
      Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); 
      batch.begin();
      stage.draw();
      batch.end();
}

@Override
public boolean touchDown(int x, int y, int pointer, int button) {
       stage.toStageCoordinates(Gdx.input.getX(), Gdx.input.getY(), point);
       Actor actor = stage.hit(point.x, point.y);
        if (actor != null){

            Gdx.app.log("name", actor.name);

// the actor.name is null

            Gdx.app.log("hashCode", ""+actor.hashCode());
            ((Image)actor).color.set((float)Math.random(), (float)Math.random(), (float)Math.random(), 0.5f + 0.5f * (float)Math.random());
        }
    return false;
}

.... .... ....

Actor.setUserObject(Object obj); Might also come in handy.

e.g. actors[x][z].setUserObject("nameHere");

The name is final, and as such has to be defined in the constructor.

Where you have

actors[x][z] = new Image(jewelsAtlas.findRegion(""+j+""));

Use

actors[x][z] = new Image(jewelsAtlas.findRegion(""+j+""), Scaling.none, Align.CENTER, "myawesomenewname");
