My issue

class Codechef
{
public static void main (String args)
{
String word = “Programming”;

    // Print the character 'o' (at index 4)
    System.out.println(word.charAt(4));

    // Print the character 'r' (at index 1)
    System.out.println(word.charAt(1));
}

}

My code

class Codechef
{
    public static void main (String[] args)
    {
        String word = "Programming";
        
        // Print the character 'o' (at index 4)
        System.out.println(word.charAt(4));

        // Print the character 'r' (at index 1)
        System.out.println(word.charAt(1));
    }
}
