I facing the problem with this question :

Create a class Sorter and implement the quick sort algorithm . Test with at arrays of object of 3 different classes selected from the standard Java lang package that implement the comparable integer i.e Integer etc. Include an output method in Sorter to display the contents of the array before and after the sort .

Please help me . Thanks
