The declaration ArrayList aL = new ArrayList( ); Options are:- a) compiles and runs correctly, but is not recommended b) causes a compile-time error c) compiles correctly, but causes an exception to be thrown at run time d) allows the programmer to create an ArrayList that holds integer types Note:- Please need a correct answer to this question.

C++, Please add a function where it can display the median, the maximum number, the minimum number, in an array entered by the user. Code: #include<iostream> using namespace std; class Search_Dynamic_Array { public: Search_Dynamic_Array(); int getArrSize(); void getArray(); void setArrsize(int); void setArray(int*); int getSum(int*); private: int arr_size; int arr[]; }; Search_Dynamic_Array::Search_Dynamic_Array() { //ctor } int Search_Dynamic_Array::getArrSize() { return arr_size; } void Search_Dynamic_Array::getArray() { cout << "The elements of the array are: "; for(int i=0; i<arr_size; i++){ cout << arr[i] << " "; } } void Search_Dynamic_Array::setArrsize(int s) { arr_size=s; } void Search_Dynamic_Array::setArray(int a[]) { for(int i=0; i<arr_size; i++){ arr[i]=a[i]; } } int Search_Dynamic_Array::getSum(int a[]) { int sum; for(int i=0; i<arr_size; i++){ sum +=arr[i]; } return sum; } int main() { int s=1, a[s]; cout << "Enter the size of the…

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
