Question

Given that:

String ab = "Aaron Bernstein";

String db = ab.substring(ab.lastIndexOf('e');

What will be the length of db?

Options

• 8

• 3

• 2

• 0

Answer 1

3

Explanation:

The lastIndexOf('e') method finds the last occurrence of the letter 'e' in "Aaron Bernstein", which is at index position 12. The substring(12) method then extracts everything from that index to the end of the string, resulting in the word "ein", which contains exactly three characters.
