import java.util.*;

public class arrayElement {
  public static void main(String[] args) {
    int[] forInts = { 1, 2, 3, 4, 5 };
    System.out.println(forInts[0]); // Prints 1
    
    String[] forStrings = { "hello", "hi", "how do you do" };
    System.out.println(forStrings[0]); // Prints "hello"
    
    // RANDOM ELEMENT PICK
    Random r = new Random();
    int pick = r.nextInt(forInts.length);
    System.out.println(forInts[pick]); // Picks random int and prints it
    
    int pick2 = r.nextInt(forStrings.length);
    System.out.println(forStrings[pick2]); // Picks random string and prints it
  }
