title: Math.random array length?
body: <p>This is my code, for each array we have been asked to extract a value, to make a getter a math.random and a .length. I'm trying all but purtropo I can not go on. can I come? thank you all</p>
  
  <pre><code>public Integer [] year = {2010, 2008, 2018, 2015, 1994,};
  </code></pre>
  
  <p>(Edit: Here is the code. How can I create a random and a switch with 3 case?)</p>
  
  <pre><code>utility package;
  import java.util.Random;
  public class TavoloLavoro {
    private static Integer [] year = {2010, 2008, 2018, 2015, 1994,};
    private static string [] brand = {"Fiat", "Ford", "Ducati", "BMW", "Yhamaha"};
    private static integer [] displacement = {1200, 250, 1400, 1000, 600};
    Entire static private [] times = {2,4};
    private static integer [] ports = {5, 3};
    private static power supply [] power supply = {power supply.
    private static integer [] capacity = {1000, 2000, 3000};
  }
