int s=0;
s+=Math.pow(2,3);
this line does not show possible lossy conversion whereas
int s=0
s=s+Math.pow(2,3)
the above line shows error. Any reason for this?

I assume that you forgot to add `;` at the end of each line in the second statement?! – Hasan Ali Jan 04 '22 at 11:58

1Reason is implicit casting. Mentioned here https://stackoverflow.com/questions/8710619/why-dont-javas-compound-assignment-operators-require-casting. – Nemanja Ranković Jan 04 '22 at 12:01

The problem is due to the method signature for Math.pow;. It returns the result as a double. You then attempte to return the double as an int, and that is a lossy conversion.
