Consider the following method definitions intended to find the smallest integer value in the ArrayList
parameter. You may assume that the array list contains at least one value.
I. public static int findSmallest(ArrayList<Integer› nums)
{
Integer small = nums.get(0);
for (int i = 1; i < nums.size(); i++)
{
Integer tempSmall = nums.get(i);
if (tempSmall.compareTo(small) < 0)
{
small = tempSmall;
}
}
return small.intValue();
}
II. public static int findSmallest(ArrayList<Integer> nums)
{
Integer small = nums.get(0);
for (int i = 1; i < nums.size(); i++)
{
Integer tempSmall = nums.get(i);
if (tempSmall.intValue() < small.intValue())
{
small = tempSmall;
}
}
return small.intValue();
}
III. public static int findSmallest(ArrayList<Integer> nums)
{
int small = (nums.get(0)).intValue();
for (int i= 1; i < nums.size(); i++)
{
int tempSmall = (nums.get(i)).intValue():
if (tempSmall < small)
{
small = tempSmall;
}
}
return small;
}
Which of the method definitions above will work as intended?
a . I o n l y
b . I I o n l y
c . I and II only
d . II and III only
e . I, II, and III
Solution
a. I only
II and III shows error
.
