boolean & Boolean - interchanable (where & where not)?

The above code compiles & gives output "true".
The API says public static boolean parseBoolean(String s)

I understand that because of Autoboxing feature, the code works fine.

Now can I say "We can use boolean and Boolean interchangably"? (Correct me if I am wrong)

What are exceptional case?

Hi Raja,

Good question.
Small problem...

class BooleanTest{
Boolean b;

public void display(boolean b) { //Here null can't be converted to boolean
System.out.println("Boolean b value:"+b);
}
public static void main(String... a) {
new BooleanTest.display(b);

}
}
The above gives a NullPointerException bec'ze the Booleab b is initialized to null. and when we try to convert it into primitive boolean throws NPException.

Hope this example will help you.
