Java Null Keyword - How To Use Null in Java #44

The java null keyword lets you make a String or object empty. In java, null is super important, and in this video, I teach you all about it!

String a = null;

Now if you try to use a method on "a", you will get a null pointer exception. You can't make a primitive type null.

I hope you enjoyed this java null keyword tutorial!
