How to make a regex pattern that fits

Question

I'm trying to learn regex and came across a question I cannot solve. The pattern looks like this:

A1234567 4 DFDGB

B1234567 1234 DFDRR

C1234567 12 DBFDG

The parts I want are the highlited ones. 1 letter followed by 7 numbers then a space and less than 5 numbers.

Thank you in advance!

Answer 1

If I understood correctly, then this is what you need

[A-Z]{1}\d{7}\s\d{1,5}

View details:

• [AZ]{1} - 1 letter from the AZ range
• \\d{7} - 7 digits
• \\s - space
• \\d{1,5} - numbers range from 1 to 5

Answer 2

(\w{1}([\d ]+))

This Will Work

\\w{1} - Will match 1 Letter

([\\d ]+)) - Will match any digits and spaces or ([\\d ]{1,6}) Which will only match up to 5
