        System.out.print("Enter a string: ");
        String s = sc.nextLine();

        String rev = "";
        for (int i = s.length() - 1; i >= 0; i--) {
            rev += s.charAt(i);
        }

        System.out.println("Reversed string: " + rev);
        sc.close();

Understanding Reverse String

We iterate from the last character to the first, building a new reversed string.

Note: To write and run Java programs, you need to set up the local environment on your computer. Refer to the complete article Setting up Java Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your Java programs.
