Finding Median Of Array?

I'm trying to find the median of a set of numbers inputted into an array and I wanted to know how I would pass the array to the median calculator after I use selection sort to organize the numbers.THIS IS THE CODE THAT ORGANIZES THE ARRAY:

public void selectionSort(double[] myArray) {
for (int i = 0; i < myArray.length - 1; i++)
{
int index = i;
for (int j = i + 1; j < myArray.length; j++)

if (myArray[j] < myArray[index])

[code]....

The code that finds the median will only work if the array being used is already organized. How do I pass the new sorted array to the code that finds the median?
