Answer:

Output of the above code is:


0
Today i Holiday

As the first T is present at index 0 in string s so s.indexOf('T') returns 0. s.substring(0,7) extracts the characters from index 0 to index 6 of string s. So its result is Today i. After that println statement prints Today i followed by a space and Holiday.
