assigning strings and int from a file and then manipulating the data

[NDBASS]

Hi, I am very, very new to Java and I have a homework assignment, which (obviously) I have left to the very last minute.

I have read from a file and displayed the information, and seemed to have spilt the information up into strings. Now I need to use those strings: change two of them into int and then add up the int seperately...which I have no idea how to do. Tried a number of things, such as a Demlimiter but didn't work - possibly as I did not use it correctly!

This is the information I am reading from the file

"Leeds United : Liverpool : 1 : 2
Chelsea : Manchester City : 1 : 1
Aston Villa : Middlesbrough : 3 : 1
Tottenham Hotspur : Stoke City : 0 : 0"

Can anyone help please??!!

Here is my code that I have got so far

"

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;




public class Generator {

	/**
	 * @param args
	 * @throws FileNotFoundException when the file cannot be loaded 
	 */
	public static void main(String[] args) throws FileNotFoundException {
		
		
		Scanner s = new Scanner(new File("Demo.txt"));	// create a scanner which scans from a file
		
		String line;	// stores the each line of text read from the file
		
		while ( s.hasNext() ) {
			
			line = s.nextLine();		// read the next line of text from the file
			
			String [] splitupText = "Demo.text".split(":");			// split the text into multiple elements
			
			
			
			for ( int i = 0; i < splitupText.length; i++ ) {	// loop over each element
				
				String nextBit = splitupText[i];				// get the next element (indexed by i)
				
				nextBit = nextBit.trim();						// use the trim method to remove leading and trailing spaces
				
				
				
              try {	// "try" is a special statement which allows us to deal with "exceptions"
					
					int num = Integer.parseInt(line);	// attempt to convert the String into an Integer type value
				}
					catch (NumberFormatException e) {
						
						// The number did not parse for some reason
						System.out.println("Invalid number entered");
					}

				
			
			System.out.println(line);	// output the line of text to the console
				
		}
		
		

	}

}
	
}

"

The try method doesn't parse properly and displays the error message after each string.

Like
"Invalid number entered
Leeds United : Liverpool : 1 : 2
Invalid number entered
Chelsea : Manchester City : 1 : 1
Invalid number entered"

Take the problem one step at a time. Which part of this are you working on now? Post an SSCCE that demonstrates just that part, then post a specific question about that specific part.

Programming is hard. Waiting until the last minute isn't a great idea.

When posting code, make sure you use the code tags to preserve formatting. Otherwise people won't want to read it.
