N.B. (Correction / we think it’s error/ on line 5, which is - - j instead of -j )

On the first loop it will output
100 - “I am learning Java !!”
On the second loop it will output
1 - “I found it simple, portable and secured”

This loops will be repeated 50 times since N/2 is 50 and the final keyword iteratively decrease the N until it’s null.

So a) 100 x 50 = 5000
b) 1 x 50 = 50
