Hi,

I am working on below challenge

http://codingbat.com/prob/p180920

Psedo code description of approach :
1. identify size of array.
2. create new empty array of above size
3. keep putting each element of array with above values until size

I wrote my code as below



public int[] fizzArray(int n) {
		  int size=n;
		  int[] ar=new int[size];
		  for(int i=0;i<n;i++){
		    ar[i]=i;
		  }
		  
		  return ar;
		}

Open in new window


public class FizzArrayEx {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println("fizzArray is-->"+fizzArray(4).toString());

	}

	
	public static int[] fizzArray(int n) {
		  int size=n;
		  int[] ar=new int[size];
		  for(int i=0;i<n;i++){
		    ar[i]=i;
		  }
		  
		  return ar;
		}

}

Open in new window

i got below output
fizzArray is-->[I@15db9742

I am not seeing any test results when i ran above code

How to improve my design, approach, code? please advise

The output you are seeing is the default way Java converts an Array to a String. What you might want to do is replace line 5 of the above code with this...

		System.out.println("fizzArray is-->"+Arrays.toString(fizzArray(4)));

It uses a separate utility class (java.util.Arrays) to convert the array (and it's contents) into a String for you.

BTW, I don't see anything wrong with your design or code, it works just fine in the codingbat site.

The only thing I would do differently is remove line 11, and just the variable n in line 12 (rather than size).
