A java.lang.indexoutofBoundsException is thrown.
The answer is D because the code fragment reads the file ''data.txt'' and collects all the lines in the file into a single string, separated by hyphens. Then, it prints the resulting string. Next, it attempts to read the fourth line in the file (index 3) and print it. However, since the file only has three lines, an IndexOutOfBoundsException is thrown.Reference:
