Answer #1

According to the above code,

NO OUTPUT WILL BE GENERATED

Because, you have initialized an empty string with name strings and you are trying to print the characters of str.charAt(i), in which str is not initialized.

I will write a simple code which is executable and get you understand.

Code:

  • String strings = "student";
    for (int i = 0; i <= strings.length() -1; i++)
    {
                 System.out.println(strings.charAt(i) + "-");
    }
  • OUTPUT is like below
    • s-
    • t-
    • u-
    • d-
    • e-
    • n-
    • t-

I hope the above code, information and explanation will help you out to understand!

Please comment if you have any queries/errors!

Thank you!
