Hi:

I need Java regular expression help. In a String value I want to extract a substring before the appearance of -d means appearance of first hyphen and digit.

For example:

Test-Test2-2.1.2

I want Test-Test2 value to be extracted.

Look forward to your near response.

Best Regards,

-Sunnybrad

This worked for me:

      String stest = "Test-Test2-2.1.2";

        stest = stest.replaceAll("-[\\d].*","");

        System.out.println(stest);

Open in new window




Test-Test2

Yes, but you don't need the character class

s = s.replaceAll("-\\d.*","")
