Thread: I keep getting an error message but I don't know how to fix this!

I have to create a simple program that allows the user to input the date in the following format : month day, year and the program is supposed to output the date in this format: date-month-year. My code keeps giving me that my string index is out of bounds but I don't know how to fix it. Help please!

import java.util.Scanner;
public class UserDate {
	public static void main (String [] args){
		Scanner input = new Scanner(System.in);
		String userDate = null;
		String month = null;
		String day = null;
		String year = null;
		int firstBlank = 0;
		int comma = 0;
 
 
		System.out.println("Please enter month day, year in that format");
		userDate = input.nextLine();
 
		firstBlank = userDate.indexOf(0,' ');
		comma = userDate.indexOf(' ', ',');
 
		month = userDate.substring(0,' ');
		day = userDate.substring(' ',comma);
		year = userDate.substring(comma);
 
		System.out.println(day + "-" + month + "-" + year);
 
}
}

note that the ' ' is supposed to represent a space

Always include the full text of the error message with your code and question

Never mind I resolved it, thanks though!
