15. (A) Statement I is true whenever s2 occurs in s1. For example, if strings s1 = “catastrophe” and s2 = “cat”, then getString returns “cat”. Statement II will never happen. If s2 is not contained in s1, the indexOf call will return –1. Using a negative integer as the first parameter of substring will cause a StringIndexOutOfBoundsException. Statement III will be true whenever s1 equals s2.
