Null Pointer Exception at batch.begin() LibgDDX

I am trying to draw a .png to the screen, but I keep getting an error. The class I am working with is a subclass of Screen.

Here is the error I get:

FATAL EXCEPTION GLThread 1335 java.lang.NullPointerException  at SplashScreen.java.32

this line is:

batch.begin()

Here is my code inside of the Screen subclass:

private SpriteBatch batch;
private Texture splashTexture;
private Camera camera;


 final int CAMERA_WIDTH = Gdx.graphics.getWidth();
static final int CAMERA_HEIGHT = Gdx.graphics.getHeight();



@Override
public void render(float delta) {
   Gdx.gl.glClearColor(0, 0, 0, 1);
   Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
   batch.begin();
   batch.draw(splashTexture, 0, 0);
   batch.end();

}

@Override
public void resize(int width, int height) {
   // TODO Auto-generated method stub

}

@Override
public void show() {
   splashTexture = new Texture(Gdx.files.internal("splash.png"));
   camera = new OrthographicCamera(CAMERA_WIDTH, CAMERA_HEIGHT);
    camera.position.set(CAMERA_WIDTH, CAMERA_HEIGHT, 0);
}

Your SpriteBatch is null, you create your texture and your camera but you don't create the batch. the breakpoint you mention has nothing to do with it.

private SpriteBatch batch;
private Texture splashTexture;
private Camera camera;

...

@Override
public void show(){
    splashTexture = new Texture(Gdx.files.internal("splash.png"));
    camera = new OrthographicCamera(CAMERA_WIDTH, CAMERA_HEIGHT);
    camera.position.set(CAMERA_WIDTH, CAMERA_HEIGHT, 0);

    batch = new SpriteBatch(); //create it like this.
}

...
