Code Challenge error java.lang.NullPointerException (Look around JavaTester.java line 250)

In the Code Challenge: Creating a Model Object, on the last Challenge Task my code is as follows:

public class Movie {

private String mTitle; private int mYearReleased;

public String getTitle() { return mTitle; }

public void setTitle(String mTitle) { mTitle = mTitle; }

public int getYearReleased() { return mYearReleased; }

public void setYearReleased(int mYearReleased) { mYearReleased = mYearReleased; } }

When I check the preview it returns:

java.lang.NullPointerException at JavaTester.run(JavaTester.java:250) at JavaTester.main(JavaTester.java:41)

What is going wrong here?

the code is

code.java 
public class Movie {
private String mTitle;
  private int mYearReleased;

  public String getTitle () {
  return mTitle;
  }
   public void setTitle (String title) {
  mTitle = title;
  }
  public int getYearReleased () {
  return mYearReleased;
  }

  public void setYearReleased (int yearReleased) {
  mYearReleased = yearReleased;
  }

}

That worked, thank you! Looks like I had some inaptly spelled variables. The part that really through me off was the error message. It said something about lines 250 and 41, which I assumed had to do with the code that checks the answer, it just really confused me.

The code challenge says you to ignore m prefix.But you are not ignoring m prefix.That will be the cause for your error. Thank you!
