Why does Collections.shuffle() fail for my array?

Question

Why does my code not work?

package generatingInitialPopulation;

import java.util.Arrays;
import java.util.Collections;

public class TestShuffle {
    publi         


        

Answer 1

Store the list resturned by Arrays.asList and shuffle that...

List myShuffledList = Arrays.asList(arr);
Collections.shuffle(myShuffledList);
