ascii is an array of integers which contains ascii codes of Characters A, B, C, D. String(ascii, 1, 3)
is an constructor which initializes s with Characters corresponding to ascii codes stored in array ascii,
starting position being given by 1 & ending position by 3, Thus s stores BCD.
output:
$ javac String_demo.java
$ java String_demo
BCD
