hi can you please help me write this code in java please. here is the prompt.

Complete the two methods in the given program. 6.1 Write a method int[] copy (int[] a) that returns a copy of the array a. To do this, you will need to create a new array of the same length as a. Then, copy each element in a to the new array. Last, return the new array which contains the same elements as the array a. 6.2 Write a method double median(int[] a) that returns the median.

If the length of the array is even, there are two middle values so median is the average of the two values in the middle
