java - Regex that excludes filename with certains extensions -

this question has answer here:

• how restrict file types , allow others in regular expression asp.net 1 answer

i trying find regex allows filename not have certains extensions. example:

• test.pdf => ok
• test.exe => ko
• test.tmp => ko
• test.exe => ko
• test.pdf => ok

i can't use ends because have put entire regex in .properties file.

i tried ^.*\.(^exe|^tmp)$ not work @ all.

edit: not duplicate of regex file extension because need ignore extensions. not purpose of other question.

hope might help!

output:

test.pdf : true test.exe : false test.tmp : false test.exe : false test.pdf : true
