Answer 1

just do something like this
do {
novo[q-1] = arr[a];
q--;
a++;
} while (q>0);
System.out.println(novo);

ofcourse theres easier ways to reverse a string in java

Answer 2

in your code you can just do:
char[] arr = scanner.nextLine().toCharArray();
the problem in your code is that you are going out of bounds
if u have the string "Hello" the length is 5 but its position in the array is 4, because we start from zero, so you can't do novo[5]
in your code you should do novo[q-1] = arr[a];
and theres reallly no need for that if(a==z) you can just print it outside the do-while
and your condition for the do while can be while q>0

Answer 3

Thanks so much for the help and the explanation!!
