Question

I’m looking for a regular expression for
(digit/digit), like (1/2)

Digit has to be 1-3 numbers. I use Java.

I think my problem is deeper than just regular expression. I can’t get this working

   String s ="(1/15)";
   Assert.isTrue(s.contains("\\d{1,3}/\\d{1,3}"));

The test fails, even thought it should contain the required text.

Answer 1

Try this

\(\d{1,3}\/\d{1,3}\)

In java you have to do

s.matches("\\(\\d{1,3}\\/\\d{1,3}\\)");

to check for the match (watch out for the escape sequences)
