what's the problem with this code?

Question

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();

//your code goes here
char []arr = new char [text.length()];
int l=0;
for(int i=text.length()-1;i>=0;i--)
{
char arr[l]=text.charAt(i);
l++;

}
String reverse ="";
for (int i=0;i<text.length();i++)
{
reverse+=arr[i];

}
System.out.println(reverse);
}
}

Answer 1

This code works correctly:

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 reverse ="";
for (int i=0;i<text.length();i++)
{
reverse+=arr[text.length()-1-i];

}
System.out.println(reverse);
}
}

Answer 2

1. You created arr array twice.
2. reverse+=arr[text.length() -1- i]

Answer 3

thank you bro
