Subject: Search for duplicate elements in the array

Hello.
I have a pretty good working Java method, which sorts array of
strings, then searches for duplicate elements. If element is
duplicated output shows ">> hello *20 times" for example.

private void printArray()

	{

		String arr[] = str.split("\\n+");



		Arrays.sort(arr);



		for (int j = 0; j < arr.length; j++)

		{

			int count = 1;

			for (int i = j + 1; i < arr.length; i++)

			{

				if (arr[i].compareTo(arr[j]) == 0)

				{

					count++;

					j++;

				}

			}

			if (count > 1)

			{

				System.out.println(">> " + arr[j] + " *" + count + " times");

			} else

			{

				System.out.println(">> " + arr[j]);

			}

		}

	}


But the problem is that I can't write this method in Ruby! How to make
this in Ruby?
