LibGDX - What is the different between batch.begin(); and renderer.getBatch().begin();?

Question

I am learning LibGDX using Tiled Map. I came across the following two render methods. The first one is simple one that I normally use.

However, I don't understand why we need the second one. Can I use batch.begin(); in method2 as well.

Thanks

Method 1

private Batch batch;

batch=new SpriteBatch();

public void Render(float delta){
......
    batch.begin();
    batch.draw(......); 
    batch.end();
}

Method 2

private OrthogonalTiledMapRenderer renderer;
private Batch batch;

public void Render(float delta){
......

        renderer.getBatch().begin();
        renderer.getBatch().draw(......);
        renderer.getBatch().end();
}

It's pretty much the same. Here you can see that in case you do not supply a Batch to the renderer, it will create a new Spritebatch() itself. You can, however, also supply your own Batch to the renderer.

The OrthogonalTiledMapRenderer extends BatchTiledMapRenderer, which will call Batch.begin() and end() itself, so you do not have to care about that.
