Regex for special characters inside brackets

Question

I've the below string, Now I want to match the string if it contains Continue? [Y/N]. I tried couple of ways but it didn't worked as expected. Any suggestions to match the complete string if contains Continue? [Y/N]

Input String:

Warning: do you want to proceed, some-more,text. Continue? [Y/N]

`[` and `]` need to be escaped if you want to match them literally. Try preceding your brackets with `\\` — a.deshpande012, May 27 '20 at 02:21

Try the following regex:

(?=^.*Continue\? \[Y\/N]$)(^.*Continue\? \[Y\/N]$)

The first group is a positive look ahead checking whether Continue? [Y/N] exists at the end of the line or not, if it exists the second group matches the whole string , you can see test cases at link given below. Note: the special characters has to be escaped to match it literally, [ , ? and /. since you are using java you need also to escape, \ .

(?=^.*Continue\\? \\[Y\\/N]$)(^.*Continue\\? \\[Y\\/N]$)
