Shuffling array in Java -

I'm messing with some sample code which, by default, prints an array of stars shown at the top of the code I would like to do random randomly pasted I see how the array is displayed. I tried to add the collection. Shuffle (message); Where is declared directly under the array, but it does not work. I have used the proper import, so there is no issue. How do I arrange the array in a random way, it is not a good idea, but this is the best effort I can get from research. Can anyone help?

Runable by class creator {Private blockquizs & lt; String & gt; Drop; & Lt; String & gt; Message = Arrays.asList ("Mares Oats", "Oats Eats", "Little Lumbers Ivy", "Do not You Evil?"); Public Producer (Blocking Qiu; String & gt; D) {this.drop = d; } Public Zero Run () {try (for string: s: messages) drop.put (s); Drop.put ("full"); } Hold (Interrupted exception intEx) {System.out.println ("Interrupted!" + "Last one out, turn out the lights!"); }}} Class consumer equipment runnabl {private blockyQUU < String & gt; Drop; Public Consumers (BlockingQueue D) {this.drop = d; } Public run to zero () {try {string msg = null; While (! ((Msg = drop.take ()). Equals ("done"))) System.out.println (msg); } Hold (Interrupted exception intEx) {System.out.println ("Interrupted!" + "Last one out, turn out the lights!"); }}} Public Sector SynQApp {Public Static Zero Main (String [] Args) {BlockingQuei & lt; String & gt; Drop = new synchronous sign & lt; String & gt; (); (New thread (new producer (drop))). Start (); (New thread (new user (drop)). Start (); }}

This should work:

  Public Zero Run (collection) {Collection. Shuffle (message); // Randomizing the array before adding it to the queue {for (strings: message) drop.put (s); Drop.put ("full"); } Hold (Interrupted exception intEx) {System.out.println ("Interrupted!" + "Last one out, turn out the lights!"); }}
