The code fragment is creating a string variable “a” with the value “Hello! Java”. Then, it is printing the
index of “Java” in “a”. Next, it is replacing “Hello!” with “Welcome!” in “a”. Then, it is printing the
index of “Java” in “a”. Finally, it is creating a new StringBuilder object “b” with the value of “a” and
printing the index of “Java” in “b”. The output will be 8109 because the index of “Java” in “a” is 8, the
index of “Java” in “a” after replacing “Hello!” with “Welcome!” is 10, and the index of “Java” in “b” is
