Need to create a loop that selects a random array from an array list

This is the code I have so far.

package milestone.pkg4;
import java.util.Arrays;
import java.util.Random;
import java.util.Scanner;
public class Milestone4 {
 public static void main(String[] args){
    new Milestone4().shoutOutCannedMessage();

}
 public String shoutOutCannedMessage(){
    String[] messages;
     messages= new String[10];
      messages[0]="I like HipHop";
      messages[1]="I like Rock and Roll";
      messages[2]="I like movies";
      messages[3]="I don't like action films";      
      messages[4]="I'll watch anything with Jackie chan!";      
      messages[5]="Will Smith is a great actor";        
      messages[6]="Lebron James is a beast";        
      messages[7]="I like homecooked food";
      messages[8]="I like chinese food";        
      messages[9]="I love pizza";

    for (int i=0; i<messages.length; i++)
    {
        System.out.println("choice["+i+"]:" + messages[i]);//prints messages
    }
      System.out.print("Please choose the message to which you relate: ");
    //user input section
      Scanner userInput= new Scanner(System.in);
        int sel= userInput.nextInt();/**looks for the number a user selects
        * as their response*/
        String userSelection= messages[sel];

        System.out.println(userSelection);
        return null;
 }

//Random shout
   public String shoutOutRandomMessage(){
     String[] subjects={"law", "football", "movies"};
     String[] objects={"ball", "knife", "sneaker"};
     String[] verbs={"fleeing", "thrashing", "petting"};
     String[] adverb={"softly", "belligerently", "expressively"};
     String[] adjectives={"disgusting", "short", "bubbly"};

//random number generator**

the code needs to pick one random word from each array in the shoutOutRandomMessage(). It then needs to print the selected words in this order (subjects-verbs-adjectives-objects-adverb).

I am new to java. I tried loops and used random generators but it happened to print out all the objects in the array lists in the order i needed. Not, just one randomly selected object from each array list. Please help.
