How do I check if a list of characters are in a String, for example \"ABCDEFGH\" how do I check if any one of those is in a string.

This seems like a Homework question... -_-

You can use the String.contains() function.
For example:

"string".contains("a");
String str = "wasd";
str.contains("a");

but you will need to call it once per every character you want to check for.
