title: Meaning of @Nullable java (android)
body: <p>I saw this video on how to create fragments in Android and I'm unable to understand the meaning of @Nullable here. 
  Also in the video (thenewboston) @Nullable was used on parameter:</p>
  
  <pre><code>@Override
  public View onCreateView(LayoutInflater inflater,@Nullable ViewGroup container,@Nullable Bundle savedInstanceState)
   {
  return super.onCreateView(inflater, container, savedInstanceState);
      }
  </code></pre>
  
  <p>But later on when I tried to create the same override method Android Studio generated this:</p>
  
  <pre><code>@Nullable
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  
  }
  </code></pre>
  
  <p>Can someone please explain me the use of @Nullable here?</p>
