Answer 1

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

String x = "Trial Letter";
char[] y = x.toCharArray();
int size = y.length;
char[] a = new char[size];

int i = 0;
while(i != size){
a[i] = y[size - 1 - i];
++i;
}

String reverse = x.replace(x,String.valueOf(a));

System.out.println(x);
System.out.println(a);
System.out.println(reverse);

}
}

Agron Check your while loop. It will be like this

while(i != size) {
a[i] = y[size - 1 - i];
i++;
}

Answer 5

you're on the track with your code with those commented lines.

Answer 6

if each character are unique, you can use my first answer. but it isnt, the only way i can think of by using your method which you almost got it.

copy the string, reverse it.
use replace with it.

Answer 7

replace char at 0 with chat at n
then char at 1 with char at n-1
etc.

depend on the string this may not work

Answer 8

i check your code. you're using nbsp instead of normal space.

its funny that non breaking space is actually breaking the program

Answer 9
