How to check for multiple conditions

Code Help Java
1

Question:
So, I would like to check for multiple words in an if statement (words that mean “yes”, “No” and so on.
I don’t know how to check the multiple conditions without using many x == z || y == z ||…
Any ideas are welcome!

Does it need to be in java? I know how to do it in python

yes_responses = ['yes', 'yeah', 'sure', 'ok', 'okay', 'thats right']
no_responses = ['no', 'nope', 'nah', 'no banana you can't do it', 'never']

user_response = input("Do you want to proceed using Java? ").lower()

if user_response in yes_responses:
    print("Continuing...")
elif user_response in no_responses:
    print("Stopping...")
else:
    print("Give me a proper answer")

What would be the java version of

if user_response in yes_responses

I believe that if you are using arrays, this will work.

import java.util.Arrays;

// in some condition
Arrays.asList(arr).contains(toCheckValue);

how would you use this in this example

out.println("Do you want cheese? ($" + cheesePrice + "0)");
        input.nextLine();
        while (cheese == "") {
          cheese = input.nextLine();
          Start.clear();
          if (cheese.toUpperCase().equals("YES")) {
            out.println("OK");
            total += 0.50;
          } else if (cheese.toUpperCase().equals("NO")) {
            out.println("OK");
          } else {
            out.println(REDTEXT + "Absolutely NOT!" + DEFAULTTEXT);
            cheese = "";
          }

It would be,

if (yes_responses.contains(user_response)) {}

Assuming that yes_responses is of type String[]

Should be:

'no banana you can\'t do it'

Thank you. I will try to implement this asap.

One thing, this only works for an arraylist.
