How do I compare a string in an array to a string?

Question

EDIT: IT'S FIXED, THANKS FOR THE HELP!

So basically I have an array of strings, a question and an answer

public static String[][] triviaData = { 
    {"Question2", "Answer1"},
    {"Question2", "Answer2"},
    {"Question3", "Answer3"},
};

And I am trying to make a method that validates an entered input, lets call the entered input enteredAnswer. enteredAnswer is stored as a String.

I am trying to validate that the enteredAnswer is the same as the second index of the array.

if (enteredAnswer.equalsIgnoreCase(triviaData[Config.CurrentQuestion][1])) {

This is the code I tried, but I get the error "Cannot invoke equalsIgnoreCase(String) on the array type String[]"

I am a beginner programmer so if you could help me out it would be highly appreciated. Thanks.

enteredAnswer is stored as

public String[] enteredAnswer;

The reason your code invocation isn't working is because enteredAnswer is a String[], not a String. Specify which element you want to use to get the String you want.

enteredAnswer is an array it appears. You need a String to call equalsIgnoreCase on, could you show a little more code?

Also, It'd probably be better to use something like a HashMap to store questions + answers. You could do this like so:

HashMap<String, String> questionAnswers = new HashMap<String, String>();

And later

questionAnswers.put("Blah blah?", "blah.");

And to check if an answer to a given String question String question with answer String answer just do:

String realAnswer = questionAnswers.get(question);
boolean correct = realAnswer.equalsIgnoreCase(answer);

it's not an array, it's stored as public String[] enteredAnswer, the array it's referring to is triviaData also thanks, I will look into hashmap but for now its only using a few questions.
