using regular expression in java

Question

I am new to regular expressions. I am using java regular expressions to match the following cases:

 - DOC_BS [\bDOC_[A-Z]+] and it works fine
 - DOC_BS1

How can i match both of the above statements in single regular expression statement. Thanks.

What is the text you want to match and what is the regular expression? Your question is hard to read. — user1907906

You can add \d* for zero or more digits.

Or change [A-Z] to [A-Z|\d] if digits can be on any place after underscore character.

if you'r okay with finding all numbers and letters after "_" extend the letter qualifier with 0-9

[\bDOC_[A-Z0-9]+]

If you would rather find the letters and numbers separately, use the following:

[\bDOC_[A-Z]+[\d]*]
