Question
public static ArrayList<Integer> doArrayListSearchGreatest(int numItems) {
System.out.print("doArrayListSearchGreatest: ");
ArrayList<Integer> list = new ArrayList<>();
// TODO Write code that adds integers 0 through (numitems - 1)
// to list.
long startTime = getTimestamp();
// TODO Write code that gets the element at the last index from list.
long endTime = getTimestamp();
long totalTime = endTime - startTime;
System.out.println(totalTime);
return list;
}
Explanation / Answer
Code that appends integers 0 through (numitems - 1) to the list. I have added a loop for adding values to the list
for(int i=0; i<numItems-1; i++){
list.add(0);
}
Then the entire program becomes
public static ArrayList<Integer> doArrayListAdd(int numItems) {
System.out.print("doArrayListAdd: ");
ArrayList<Integer> list = new ArrayList<>();
for(int i=0; i<numItems-1; i++){
list.add(0);
long startTime = getTimestamp();
}
// TODO Write code that gets the element at the last index from list.
int lastNumber = list.get(list.size()-1);
long endTime = getTimestamp();
long totalTime = endTime - startTime;
System.out.println(totalTime);
return list;
}
