如果发生异常，如何继续循环迭代？

Question

Hey I'm totally finished with my try-catch block, but have question. I want to count how many words and numbers a string contains. For this i want to use a try - catch block. I parse the String to an int, and if the output is false, I want to count the number of words within the catch block logic. But after the program enters the catch block, the program exits. I want to continue iterating through the loop following the caught error. How can I make this happen?

    Scanner odczyt = new Scanner(System.in);
    String zdanie = odczyt.nextLine();
    String[] podzdania = zdanie.split(" ");
    boolean exception = false;
    int numberword = 0;

    try {

        for (int i = 0; i < podzdania.length; i++) {
            Integer.parseInt(podzdania[i]);
        }

    } catch (NumberFormatException e) {

        numberword++;

    }

Answer 1

Move the try-catch block within the loop:

for (int i = 0; i < podzdania.length; i++) {
  try {
    Integer.parseInt(podzdania[i]);
  } catch (NumberFormatException e) {
    numberword++;
  }
}

I would avoid using exceptions as a flow control mechanism though. Check this StackOverflow question for alternatives to validate the string before actually parsing it.
