Capital N, Null is not a keyword or a reserved word.

All small letters, null is not a keyword either. but, it's a reserved word. you cannot use null as follows:

String null = "a";

null means that a reference is not pointing to any object.

Null is not a keyword but

null is a keyword but it is not a good programming practise that u use variavles that

may be close to some keywords .

Null is a variable that can hold any of the value;
while  null means nothing or empty;
it is used to specify the objects that do not point anything
eg:
Myclass ob=null; //null object
or String s1=null;

"null" is not a keyword, but a special literal of the null type. It can be cast to any reference type, but not to any primitive type such as int or boolean. The null literal doesn't necessarily have value zero. And it is impossible to cast to the null type or declare a variable of this type.

Null is not a keyword but null is reserved literal. null is the default value for instance variable.
String str = null;
means instance variable str does not hold reference of any object.
