There is no NullReferenceException in Java. It's a .NET class, which is the equivalent of Java's NullPointerException.

NullPointerException - The Java exception thrown when an application attempts to use null in a case where an object is required.

NullReferenceException - The exception that is thrown when there is an attempt to reference (or use) a null or uninitialized object.

There is no 'NullReferenceException' in Java. Java has an equivalent class 'NullPointerException'.
