Would someone help me with Searching and Sorting Arrays?

[Bull Horn]

This is basically what I have to do. I think I have the methods correct in terms of sorting, but how do I switch it from largest to smallest?

The selectionSort method should take an array of integers as a
parameter and will sort the numbers into order from largest to smallest.
Place a println statement in the sort so every time a new maximum is
found, it is printed to the screen. Once all are sorted, the method should
print the array to the screen on the same line. Note that this method should
change the original array and because arrays are passed by reference, the
method does not need to return anything (the passed array will be changed
at the source), so the return type should be void.

The insertion method should take an integer and an array as
parameters. This method will create a new array and that will hold
the same values as the passed array, but allow for one extra space.
The integer passed to the method will be inserted into the array in the
appropriate space. This new array should be returned by the method.

list[position]= list[position-1];
