Regex pattern for numbers with dots

Question

I need a regex expression for this

any number then . and again number and .

So this is valid

1.3.164.1.2583.15.46
546.598.856.1.68.268.695.5         


        

Answer 1

Something like this should work:

(\\d+\\.?)+

Edit

Yep, not clear from the description if a final . is allowed (assuming an initial one is not).

If not:

(\\d+\\.?)*\\d+ or \\d+(\\.\\d+)* (if that seems more logical)

Test

for (String test : asList("1.3.164.1.2583.15.46",
    "546.598.856.1.68.268.695.5955565", "5..........", "...56.5656"))
    System.out.println(test.matches("\\d+(\\.\\d+)*"));

produces:

true
true
false
false
