- The declaration ArrayList<int> aL = new ArrayList<int>( ); 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.Java Exceptions Write a program that accepts an integer N which serves as the size of an array. Ask for N number of elements. After, continuously ask for user input index. Mark the element at that index as zero. If the user gives an invalid index, throw the appropriate exception and print "Illegal index!". The program ends once an exception is thrown or once the array contains only zeroes. Lastly, print the array elements separated by space. Inputs 1. Multiple lines of integer Sample Output Enter N: 5 Enter element 1: 1 Enter element 2: 2 Enter element 3: 3 Enter element 4: 4 Enter element 5: 5 Enter index: 1 Enter index: 2 Enter index: 3 Enter index: 4 Enter index: 5 Illegal index! 1 0 0 0 0Write a block of code that uses a dynamic allocated array named Array to (1) Load ten integers from the user into the memory, (2) Find the number of negative integers in the array, and (3) Print a message with the number of negatives. Whenever no numbers are negative print an additional message "No negatives!" (Assume all libraries are included)
- 4.4.1: Modify an array parameter. Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}.C++ The People class holds an unsorted list of humans. Initially, this list is empty. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full. Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for one with that name. If found, return this human. Else throw an…Below you will find code blocks necessary to insert a value into an ordered array given a position (index) to insert. Be careful! Some lines are not needed. first line COMPLETED: bool insertElement(char array[ ], int& numElems, int &capacity, in position, char value) { last line COMPLETE: bool insertElement(char array[ ], int numElems, int capacity, in position, char value) {
- For some reason I have 2 programs that aren't running. This is the second one, please let me know if everything is correct.

Usetwo interfaces for methods and throw Exception Handling for Out Of Boundindex for the arrayExercise1: Write a program that stores data for 5 students in two different arrays as follows: Name: take student’s names from the console (using Scanner object) then store their names in an array of a String data type GPA: : take student’s GPA from the console (using the same Scanner object) then store their GPAs in an array of a double data type. Exercise 5: Write a program the calculates the maximum number in an array of 10 integers. The input should be taken from the console (using a Scanner object).
- 1. Write a static method called runningSum that accepts an array parameter, populated with a sequence of real numbers that are read from a file. The program outputs the running sum of the numbers followed by the maximum running sum. For example, if the array contains the following data: 3.25 4.5 -8.25 7.25 3.5 4.25 -6.5 5.25 your method should produce the following output: running sum = 3.25 7.75 -0.5 6.75 10.25 14.5 8.0 13.25 max sum = 14.5 2. Arrays a1, a2… are populated as shown; display a[i] for each calls to arr; if a[i] less than or equal to 0 display a message indicating those conditions public static void arr(int[] a) { //Add the missing loop a[i] = a[i + 1] + a[i - 1]; // display a[i] } }Write a program that takes an integer array and perform following operations sum, average, percentage,. The user must non zero integers. If they were not an integer, the program would throw a NumberFormatException if user try to input string instead of integer value. If denominator were Zero, the program would throw an ArithmeticException and Display the exception.If you use the BinarySearch() method, and the object you seek is not found in the array, _______________________. a. an error message is displayed b. the value false is returned c. a negative value is returned d. a zero is returned
