Split up string into pairs of numbers

[Alissa Horner]

I have a text file that contains the following:

3,5,6,7,34,89,23.66,89.5,90.22,100.33,45.33,78.44

I would like to split it up into pairs of numbers. For the first pair, I would like the first number to be 3 and the second number to be 5. For the second pair, the first number should be 6 and the second number should be 7 and so on. How would I do this in Java?

Have you tried anything so far?

One way would be to read the whole line of text into a String and use the split() method to get a String[]
From there it should be trivial to split the numbers into pairs.

You can create a Scanner from that String and tell is to use the comma as a delimiter.

I have the following:

String input = "12 45 44 6 74 75 8 56 44";
String[] pairs = input.split("(?<!\\G\\d+)\\s");


How would I change this so that it can handle numbers with a decimal point?

What happened to the commas?
The string split method works by default with commas.

I would put the commas back in, and remove the regular expression.
