Question
Implement a static generic method named problem4_isDecreasing that takes as a parameter a
generic list and returns true if it its elements are in decreasing order, or false if not. Decreasing order
in this case means non-increasing, so there can be multiple equivalent elements next to each other (e.g.,
4, 2, 2, 0) and it will still be considered decreasing. Require that the list elements implement the
Comparable interface.
Examples:
List<String> a - new ArrayList<> ();
a. add ("cupcake");
add ("banana");
a. add ("apple");
problem4_isDecreasing (a); // returns true
a.
List<String> b - new ArrayList<>();
b.add ("banana");
b.add ("pear") :
problem4_isDecreasing (b); // returns false
List<Integer> c - new ArrayList<> ();
for (int i - 0; i < 10; i +- 2) {
c.add (i);
problem4 isDecreasing (c); // returns false;
List<Integer> d = new ArrayList<> ();
for (int i - 10; i >= 0; i -- 2) {
d. add (i);
problema_isDecreasing (d); // returns true
