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!

I am trying to take a string of numbers seperated by a single space and covert them into a string array. I have created the following code but it only works if the numbers are seperated a a comma or something similar to that. Example of what I am trying to achieve: string input = "1 1 1 1 1" turn it into.... int[] x = {1,1,1,1} so that it is printed as... [1, 1, 1, 1]    This is...
