Java help, Array Reverse a string project!

Question

I keep getting an "illegal start of type" error but I can't find what is wrong. Any help would be much appreciated!!

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
}

String y ="";

for(int x=arr.length-1; x>=0; x--){
y = y + arr[x];
}

System.out.println(y);
//your code goes here

}
}

Your code is right but you have closed main method after taking input. So just remove } before the declaration of y.

{
// this is a block of code
// you cannot access this scope variable outside of this block.
//so you have declared arr inside this block so you cannot access outside, that is why you are getting error.
}

Answer 4

StringBuilder way, if you want :

String text = scanner.nextLine();
StringBuilder st = new StringBuilder(text); //create stringbulider for text
System.out.println(st.reverse()); //reverse method

hope it helps...
