Java正则表达式匹配列表中的前6位数字

Question

I have a range of numbers separated by comma, which is stored in a csv file. I am trying to match first 6 digits, for example: "130001X, XYZ" can be considered a group of digits in which X can be anything (0-9).

Is it possible? Can I use Java regular expression to match these and group them to a list?

Thanks!

1300010,10 1300011,10 1300012,22 1300013,22 1300014,22 1300015,533 1300016,535 1300017,531 1300018,22 1300019,22

1300050,20 1300051,20 1300052,20 1300053,20 1300054,20 1300055,20 1300056,20 1300057,20 1300058,20 1300059,20

Answer 1

I'm not sure if I understood your question. But if you want to match the numbers having 13000x,xxx then you can use a regex like this:

\b130001\d,\d{3}\b

Answer 2

Assuming that X is the same in X,X and YZ are also two random digits

\b130001(\d),\1\d{2}\b
