Regex to find integer or decimal from a string in java in a single group?

Question

I am trying (\\d+|\\d+\\.\\d+) on this sample string:

Oats     124   0.99        V    1.65

but it is giving me decimal number

Answer 1

Question not entirely clear, but the first problem I see is . is a magic character in regex meaning any character. You need to escape it with as . There are lots of regex cheat sheets out there, for example JavaScript Regex Cheatsheet

(\d+|\d+\.\d+)
