Parsing a String Program Help

[Nicole Miller]

Hi, I'm looking for help on a program where the user enters a string of text (can be anything), and the program has to pull all the integers out of that string and put them in an array to be printed. I need to use a method to do this. So, for example, if the user inputted: sfd0jd-2jf93jf0, the array would need to contain 0,2,93,0. Here's what I have so far, but I'm now stuck and don't know what I'm doing wrong. Any advice would be great!

import java.util.Scanner;
public class THE2 {	
public static void main(String[] args)
{
	System.out.println("Integer Parsing Program\n************************");
	boolean play = true;
	Scanner myscan = new Scanner(System.in);
	while (play)
	{
	
	System.out.println("Please enter a string: ");
	
	String stringiness = myscan.nextLine();
	int[] myarray = new int[stringiness.length()];
	myarray	=intParse(stringiness);
	for (int i=0; i<myarray.length; i++)
	{
		System.out.println(myarray);
	}
	}
	System.out.println("Do you wish to continue playing [y,n]? ");
	String answer = myscan.nextLine();
	if (!(answer.charAt(0) == 'y' || answer.charAt(0) == 'Y'))
		play = false;
}
public static int[] intParse(String stringiness)
{
	int a=0;
	boolean keepgoing = true;
	String temp = "";
	int[] temparray = new int[stringiness.length()];
	while (keepgoing)
	{
		while (Character.isDigit(stringiness.charAt(a)))
		{
			temp+=stringiness.charAt(a);
			a++;
		}
		System.out.println(temp);
		if (Character.isDigit(stringiness.charAt(a)))
		{
			a++;
		}
		if (stringiness.charAt(a) == stringiness.length()-1)
			keepgoing = false;
	}
	return temparray;
}
}

You could use a Scanner class with a delimiter with a pattern (a regular expression) to match non digits. I wrote a test program and got a print with about 4 lines with this approach.. hope this helps..

Here's what your intParse() should do;

intParse(StringExpression)
{
   ArrayList result;
   isDigitFound = false;
   temp = ""
   for(each char 'c' in string StringExpression)
   {
       if(c) is digit
       {
            temp = temp + c
            isDigitFound = true;
       }
       if(c) is character)
       { 
            check if we found a digit before if(isDigitFound )
           {
                 Store the previous digits found 'temp' in an array and reset 'temp' and 'isDigitFoundFlag'
           }
       }
  }//End for

  //For the boundary condition when the last digit is a number.
  check if we found a digit before if(isDigitFound )
  {
         Store the previous digits found in an array and reset temp and isDigitFoundFlag
   }
}

By the way this is pretty similar to you code which is almost correct, except for two facts.
1 it does not store the result 'temp' in tempArray
2. The lines

if (stringiness.charAt(a) == stringiness.length()-1)  
            keepgoing = false;

should have been

if (a == stringiness.length()-1)  
            keepgoing = false;

Thanks to both of you for the help! I'm all finished and it works great!
