Classes and Arrays

[Dillinger4]

Do you mean somthing like this?

public class Q{
     public static void main(String[] args){
       double d = 1.5;
       Z[] z = {new Z()};
       long  l =  z[0].round(d);
      System.out.println(" The value of " + d + " rounded " + " = "  + l);
  

    }
}

class Z{
   public long round(double d){return Math.round(d);}  
 }
