How to detect a list of words within a TextBox

Discuss
#1

I have a problem, I try to store a list of words that I want to detect within a textbox (avoid rude words and warn them that it cannot be used), the thing is that it does not work correctly for me.

I leave the TextBox empty and I get the message, it only detects the first word in the list but not the others, these are separated by commas “,”.

Words example list: word1, word2, etc.
The list of comma-separated words I am extracting from a tinydbweb.

What am I doing wrong?

Hello @losasencio

Since you are working with list consider using is in list block instead of contains block


where your list goes in the list socket and the textbox’s text goes in the thing socket

Try using for each item in list block and split text_box1.text at spaces.

      for(String s : text){
      for (String b : list){
      if(s == b){
     System.out.println("Delete bad words");
       }
      }
       }
