I read the article Marcus Green put on the web and it says that
the >> and << can never cause a number to change it sign. I agree that >> will never change a number's sign. but I think << CAN change a number's sign.
for example, try this in main():
int n = 11;
n<<=28;
System.out.println("n = "+n);
you will see that the output n is a large NEGATIVE number. that means it went from positive to negative. this happened when a '1' is shifted to the left most position. and when that happened, the number became too large to fit the int range and it "wraps around" to be a large negative number.
can anyone clear my doubts on this? am I understanding this correctly?
thanks a lot.

I think you are right. Left shift operator can change the sign.
