Question

Say I have a class like this:

public class EnglishWords {

    private final String word1;
    private final String word2;
    private final String word3;
    private final String word4;


    public EnglishWords(String word1Arg, String word2Arg, String word3Arg, String word4Arg) {
        this.word1 = word1Arg;
        this.word2 = word2Arg;
        this.word3 = word3Arg;
        this.word4 = word4Arg; 
    }

    public String getword1() {
        return word1;
    }

    public String getword2() {
        return word2;
    }


        public String getword3(){
            return word3; 
        }

        public String getword4(){
            return word4; 
        }
    }

I create an object like this:

EnglishWords englishWords = new EnglishWords(words.get(0),
                words.get(1), words.get(2), wordPair.getEnglishWord());

Is there some kind of sort method I can add to the class that shuffles the members so they are ordered randomly?

Answer 1

Yes. You can hold them in a List and use Collections.shuffle() to shuffle the list.

If you are eager to shuffle it by your own, or interested how it can be done – fisher-yates algorithm gives a uniformly distributed permutation of a given list.
