AvoidThrowingNullPointerException

AvoidThrowingNullPointerException

Avoid throwing NullPointerExceptions. These are confusing because most people will assume that the virtual machine threw it. Consider using an IllegalArgumentException instead; this will be clearly seen as a programmer-initiated exception.

Example(s):


        
public class Foo {
  void bar() {
    throw new NullPointerException();
  }
