How to delete all lines with the specified letter [SOLVED]?

Question

Java

Hello, tell me how to get out, there is a code:

ArrayList <String> list = new ArrayList();
      list.add("коля");
      list.add("воля");
      list.add("боля");

I need to delete all lines with the letters "K", how can I do this? I tried to do like this:

for(String s : list){
  if(list.contains("к")){
  list.remove(s);

But the result is zero, please tell me how to be, thanks in advance !!!

Answer 1

1. it's not good to delete the elements of the list you are running through
2. you need to look for the character in the string, not in the list

for(String s : list)
    if(s.contains("к"))
        list.remove(s);

3. I would make a copy of the list and run along the copy, and already delete elements from the target
