Hey,
I have an assignment to do. I have to read a text file in using the scanner in java, getting it to read the football scores within the file and split them into 4 parts. So basically the files has Home team : away team : hometeam score : away team score. on one line and has multiple lines for multiple games.
I then have to re-arrange them so it displays them neatly. I also have to do the score count. I have done all this above (yay) but im really struggling with having it count if a line is valid. I have so far done it so it counts the string for each segment and if it contains <=0 characters it doesn't display the match but i need to count how many matches are invaild and how many are vaild. For example one line might have a missing score or a missing team name.
I hope this makes sense!
Here is my working code so far:

) because one tends to get confused by all the little details and lose sight of the forest for the trees, if you will.
