boolean longEnough = password.length() >= 8;

boolean hasDigit = password.indexOf("1") >= 0;

System.out.println(longEnough && hasDigit);

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);
