boolean method returns null - NullPointerException

[Ramesh Kumar Swarnkar]

I have an issue, which as follows:

ObjectA contains a method [boolean IsIncluded()]which is supposed to return a boolean value.
But since the boolean value is not set into that variable which being returned by that method, neighter it is initialised.
As a consquence it returns 'null';

boolean isPresent = ObjectA.IsIncluded();

The aboce line where it is being called, throws java.lang.NullPointerException.
Any suggetion how to avoid this null pointer Exception where it is being called ? Any idea on its type casting which may avodi this problem ?

A quick response would be highly appreciated.
thansk in advance,
Ramesh.

Ramesh,

boolean isPresent = ObjectA.IsIncluded();

Its not boolean that returns null ,its ObjectA , check if its been initialised

You are welcome.

" java.lang.NullPointerException " almost always happens when we invoke a method on the object which is null.

There are lots more reasons for NullPointerExceptions. I am writing an article about it
