Question

I want to create a regex expression that generates a match and strips off the $, and the last two characters, if the last character ends in a capital letter plus a number.

I'll strip off the $ and then an ending capital letter + number:

$mytestA1 --> expected output: mytest
$againD4 --> expected output: again
$something --> expected output: something
$name3 --> expected output: name3 // because there was no capital letter before the number digit
$name2P4 --> expected output: name2

I’ll have an ‘if’ check in my code that checks for the existence of a $ before I would even bother to run the regex.

Thanks.

In Java just use String#replaceAll:

String replaced = str.replaceAll("^\\$|[A-Z]\\d$", "");
