Do the same question with List Array
Write a method with the name "eraser" that will
get two arguments: “maparr_plants" (Map array
of objects of a kind of class Plant), and
"eraselist" (One dimensional array of integers).
That method should erase the elements of the
maparr_plants which their keys are matching
the elements of the eraselist.
(Hint: Check all elements of eraselist, and
erase the matching (key) elements of the
maparr_plants.)
Solution:
public static void eraser(Map<Integer,Plant>
maparr_plants,
int [] eraselist) {
for (i=0; i<eraselist.length(); i++) {
if(maparr_plants.containsKey(i) {
maparr_plants.remove(i);
}
