What is the drawback of Arraylist? Group of answer choices Arraylist uses arrays as its internal data structure ArrayList does not allow duplicate elements Arraylist is difficult to retrieve elements stored ArrayList has more runtime for insertion at any given position 2.What is the default initial capacity of a Vector? Group of answer choices 10 15 20 Same as initial size of Vector 3.What is the output of the above print statement? Group of answer choices [California, Utah, Iowa, Maryland, New York] [Iowa, Utah, Missouri, Maryland, New York] [California, Iowa, Missouri, Maryland, New York] [New York, Iowa, Missouri, Utah, California]Create a client that creates partly sorted arrays with the following features: 95 percent sorted, the remaining 5% random valuesAll entries within ten spots of the array's ultimate positionExcept for 5% of the elements, which are randomly distributed across the array, the array has been sorted. Create and test theories about how such input affects the performance of the algorithms in this section.
- For each increment, use shellsort to report the number of comparisons divided by the array size. Create a test client that tests the hypothesis that this number is a tiny constant by sorting arrays of random Double values with array sizes increasing powers of ten beginning at 100.The line np.random.random(15) will produce which of the following? 1) A one-dimensional array of NaNs 2) A one-dimensional array of integers between 0 and 15 3) A one-dimensional array of 15 zero values 4) A one-dimensional array of 15 values between 0 and 1Create a main() method in which we will create a 5 element array of RegularTriangle objects. For each element, create a random int between 1-10 and create the element instance using this number as side. Once created, calculate the average perimeter of these arrays. Hint: use the following code to generate random number import java.util.Random; Random rand = new Random(); int n = rand.nextInt(100); Add screenshot of output
