length() is a method, so it needs parentheses.

Indexes go from 0 to length() - 1.

Solution explanation

charAt(i) returns a single char; strings themselves never change.

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {

        String w = sc.next();

        System.out.println(w.charAt(w.length() - 1));
        System.out.println(w.toUpperCase());
