String Manipulation Practice Test

Password Validator: What is the result of the following code snippet when the input is "Z9xxxxxx"?

String p = input;

boolean hasUpper = p.toUpperCase().indexOf(p.substring(0, 1)) >= 0;

boolean hasDigit = p.indexOf("9") >= 0;

System.out.println(hasUpper && hasDigit && p.length() >= 8);

Palindrome Checker: What will be the output if the string is "Level"?

String s = input.toUpperCase();

char first = s.charAt(0);

char last = s.charAt(s.length() - 1);

System.out.println(first == last);
