Splitting CSV file; output a simple tokenised string of doubles - HELP

Question

Okay here it goes? I have a file that contains comma delimited double values in the form;
2,3
2.8,9.0
4.8,9.0
I am trying to get the values in to the a simple string of "2 3 2.8 9.0 4.8 9.0". Therefore i have tried to replace all commas with a space and then split on whitespace? no success there?
Th other way is to split on white space string.split("\\s+") and creat a string [] array and then loop through each element of the array creating a multi dimensional array of seperated values. These i could then concatente to form a string?
My question is where is my code going wrong for spliting the string???

Answer 1

the point being there are 2 delimiters to split, the first being the comma the second being the line break thus creating an array of single digits
I have solved the issue by using replaceall to replace all commas with spaces and then split on the spaceStill makes no sense. A line break doesn't not contain spaces. So how does replacing commas with spaces allow you to split on the line break.
If you are appending each line to a string (to build one long string) then append the data with a comma, not a space.
I really get the idea you guys are not enjoying my code?Its your requirements we don't understand. You obviously aren't explaining them correctly.
