Boolean is a class. However, boolean is a primitive data type.

A primitive type boolean cannot be null in java.
however...
A class type Boolean can be null.
try this..
btw the reason the output is null is becuase var boo is not affected as boo == null is infact true.
Boolean boo = null;
if (boo == null) {System.out.println(boo);}

private boolean name = null != null;

I tried it in eclipse, you have to put private boolean (variable) = null != null;. How is that possible?

what is difference between Boolean and boolean?

Boolean (capital B) is a wrapper class
boolean (small b) is a data type.
