I need to check wether my String contains any other words than "sum", "multiply", "sqrt" and "random". Could you help me create a Pattern for this issue?

Thanks a lot, Elias

  • Looks like you are looking to create a regex, but do not know where to get started. Please check [Reference - What does this regex mean](https://stackoverflow.com/questions/22937618) resource, it has plenty of hints. Also, refer to [Learning Regular Expressions](https://stackoverflow.com/questions/4736) post for some basic regex info. Once you get some expression ready and still have issues with the solution, please edit the question with the latest details and we'll be glad to help you fix the problem. – Wiktor Stribiżew Apr 02 '20 at 10:46
