Example: How to check string is palindrome or not in java

import java.util.Scanner;

class Main {
    public static void main(String args[]) {

        Scanner s = new Scanner(System.in);

        String str;
        int l = 0, i, f = 1;

        System.out.print("Enter a string:");
        str = s.nextLine();
        char a[] = str.toCharArray();

        for (i = 0; i < a.length; i++) {
            l++;
        }

        l = l - 1;
        i = 0;

        while (i < l) {
            if (a[i] != a[l]) {
                f = 0;
                break;
            }
            l--;
            i++;
        }
        if (f == 1) {
            System.out.print("String is palindrome:" + str);
        } else {
            System.out.print("String is not palindrome:" + str);
        }

    }
}

Output:

Enter a string:level
String is palindrome:level
