Regarding expressing array in simpler terms

I am developing application..

    class Wheel {
     private int size;
 
     Wheel(int s) {
         size = s;
     }
 
     void spin() {
         System.out.print(size + " inch wheel spinning, ");
     }
 
 }
 
 public class Bicycle {
     public static void main(String[] args) {
         Wheel[] wa = { new Wheel(15), new Wheel(17) };
         for (Wheel w : wa)
             w.spin();
     }
 }
 

But Please advise that how could we express Wheel[] wa = { new Wheel(15), new Wheel(17) }; in more simpler terms.
