String input, parsing, split

Question

I need to write a program that makes a user to type string date (ex. 10/21) once, and convert that string into integers. I suppose splitting is necessary before parsing?

import java.util.Scanner;
public class ConvertDates {
   public static void main(String[] args) {
      Scanner input = new Scanner(System.in);
      System.out.print("Please input a date (mm/dd): ");
      String k = input.next();
      k = String.split("/");
      int mm = Integer.parseInt(k);
      int dd = Integer.parseInt(k);

When you split a string, you don't get a string, you get an array of strings. So you would need to call

String[] k2 = k.split("/");

then you can get your month and day with

int mm = Integer.parseInt(k2[0]);
int dd = Integer.parseInt(k2[1]);

String[] tokens = k.split("/");
int mm = Integer.parseInt(tokens[0]);
int dd = Integer.parseInt(tokens[1]);

Since split() method returns string array, you have to use above code.

String#split returns a String array. You need to use the elements of the returned Array:

String[] strings = k.split("/");
int mm = Integer.parseInt(strings[0]);
int dd = Integer.parseInt(strings[1]);

Or even

   Scanner dates = new Scanner(k);
   dates.useDelimiter("/");
   int mm = dates.nextInt();
   int dd = dates.nextInt();

and then you don't need to parse the integer
