Using the @SafeVarargs Annotation

import java.util.ArrayList;

public class Test {

  public static void main(String[] args) {
    ArrayList<Integer> a1 = new ArrayList<>();
    a1.add(new Integer(1));
    a1.add(2);
    ArrayList<Float> a2 = new ArrayList<>();
    a2.add(new Float(3.0));
    a2.add(new Float(4.0));
    displayElements(a1, a2, 12);

  }

  @SafeVarargs
  public static <T> void displayElements(T... array) {
    for (T element : array) {
      System.out.println(element.getClass().getName() + ": " + element);
    }
