What does the following statement sequence print? String str = "Harry"; int n = str.length(); String mystery = str.substring(0, 1) + str.substring(n - 2, n); System.out.println(mystery);

To understand what the code prints, let's break down the string manipulations step by step.

1. String Initialization: The initial string str is set to "Harry".
2. Length Calculation: The variable n is calculated as str.length(), which gives us the length of the string "Harry". The length is 5 (since it contains five characters: H, a, r, r, y).
3. Substring Operations:
   • str.substring(0, 1) extracts a substring from index 0 to index 1 (not inclusive). Thus, this gives us the first character of the string, which is "H".
   • str.substring(n - 2, n) extracts a substring from index n - 2 (which is 5 - 2 = 3) to index n (which is 5). This means we are taking the substring from index 3 to 5. The characters at these indices in "Harry" are "r" (at index 3) and "y" (at index 4), resulting in the substring "ry".
4. Combining Substrings: The two
