Splits a string by commas and converts them into integers.

SplitInput.java

public class SplitInput {

	public static void main(String... args){
		// This is your input string.  It can be read from the console or 
		// via other methods of io, but I just have it the code for the hell of it
		String input = "20,40,30,54,17";

		// Now we split the string into an array of strings with the "split" method.
		//  It creates an array of strings that were seperated by the comma.
		String[] afterSplit = input.split(",");

		// Now we will want to go through and convert our array of strings into 
		// an array of integers, so we will initialize a new array of ints.
		int[] converted = new int[afterSplit.length];

		// Loop through and convert
		for(int i=0;i<afterSplit.length;i++){
		    // Using "Integer.parse()", you can convert the string into an int
		    converted[i] = Integer.parseInt(afterSplit[i]);
		}
		
		// Print all of our newly created integers.
		for(int i:converted){
			System.out.println(i);
		}
	}
