Hi
As I said, there are many ways to make it working and to look nice.
One way to write your code might also be:
...
for ( int i = name.length() - 1 ; i >= 0 ; i-- )
System.out.print(name.charAt(i));
System.out.println();
...
In this way neither the String ans nor the char and (nor the int l) need
to be declared.
Hope it helps

Hello Guys,
I really appreciate your responses, Thanks Alfor for introducing me to
some new methods as I really appreciate it. Also Mihai, you have been
there before now and I will say thanks to you again but why is it that
I must initialize before using the String ans? because going by your
solution, I must still have to initialize the String for it to work.
Thanks G for the Naming Convention thing as it will also go a long way.
Regards

Hi
You say "String and, ans;", then, later, "and = name.charAt(i);".
As the error message says, the method "charAt(...)" returns a
value of type "char", while your variable "and" is of type "String".
There are many ways to make your code working, but the simplest
way is to replace the line of code:
...
String and, ans;
...
by two lines:
...
String ans;
*char and;*
...
The line of code "ans = ans + and;" will still work after this
modification, as the "+" operator allows to append a char (or any
other simple type) to a String (this is what allows you to write
"for(int i = 0; i < 10; i++) System.out.println(*"Iteration # " +
i*);").
Hope it helps

Hello Guys,
I am having some problems running this program. Kindly help
import java.util.Scanner;
class backward
{
public static void main (String[] Args)
{
Scanner in=new Scanner(System.in);
System.out.print("Enter a Name to Reverse:");
String name = in.nextLine();
String and, ans;
int l=name.length();
int i;
for (i=l-1; i>=0; i--)
{
and=name.charAt(i);
ans= ans+and;
}
System.out.println("The Output is:" + ans);
}
}
The error I have is stated thus using TextPad
C:\JavaClass\backward.java:14: incompatible types
found : char
required: java.lang.String
and=name.charAt(i);
^
