Java: Check whether the string matches the pattern [x.y] where both x and y are between [0-9]

Question

Hi guys basically I need to check whether the version-no is in format x.y where both x and y should be in between[0-9] Ex:1.1, 1.2, 2.3, 4.5 etc

I am a novice to java....I was thinking of splitting the string using "." and then check whether both are integers....but i think it can be done using regex..which i am not able to do....can anyone help me in this regard...

try this regex: `\\b\\d+\\.\\d+\\b` – anubhava Nov 17 '20 at 14:50 — anubhava, Nov 17 '20 at 14:50

You can do it with regex:

str.matches("\\d\\.\\d")

\d is a digit, and \. is the literal . character.
