How do we check if a given structure error in a script ? for backend process?

// Java implementation of the approach public class GFG {

// Function that returns true if 
// str is a palindrome 
static boolean isPalindrome(String str) 
{ 

    // Pointers pointing to the beginning 
    // and the end of the string 
    int i = 0, j = str.length() - 1; 

    // While there are characters toc compare 
    while (i < j) { 

        // If there is a mismatch 
        if (str.charAt(i) != str.charAt(j)) 
            return false; 

        // Increment first pointer and 
        // decrement the other 
        i++; 
        j--; 
    } 

    // Given string is a palindrome 
    return true; 
} 

// Driver code 
public static void main(String[] args) 
{ 
    String str = "geeks"; 

    if (isPalindrome(str)) 
        System.out.print("Yes"); 
    else
        System.out.print("No"); 
} 

}

by taking two pointers i pointing to the start of the string and j pointing to the end of the string. Keep incrementing i and decrementing j while i < j and at every step check whether the characters at these pointers are same or not. If not then the string is not a palindrome else it is.

what your opinion ?
