*please help in java*   Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.   import java.util.Scanner; public class SumOfExcess {public static void main (String [] args) {Scanner scnr = new Scanner(System.in);final int NUM_VALS = 4;int[] testGrades = new int[NUM_VALS];int i;int sumExtra = -9999; // Assign sumExtra with 0 before your for loop for (i = 0; i < testGrades.length; ++i) {testGrades[i] = scnr.nextInt();} // your answer goes here// System.out.println("sumExtra: " + sumExtra);}}

Finding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run:            Enter the number of elements of array 1:  7     Enter the elements of array 1: 10 12 13  10  14  15 12     Enter the number of elements of array 2: 5     Enter the elements of array 2:  17  12  10 19 12     The common members of array1 and array2 are: 12  10

Write pseudo code for given statemente. The amount variable is set to 0, and then each is called on the array. Each of the values in the array is passed to the block. Each time the block is called, amount is updated:

Assignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…

Rotate Right k cells (use python)  Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as:   [ 40, 50, 60, 10, 20, 30]

Arrays Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTime = {800, 775, 790, 805, 808}, print:800 775 790Note: These activities will test the code with different test values. This activity will perform two tests, both with a 5-element array (int runTimes[5]). See "How to Use zyBooks".Also note: If the submitted code tries to access an invalid array element, such as runTime[9] for a 5-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() {const int NUM_ELEMENTS = 5;int runTimes[NUM_ELEMENTS];int i; for (i = 0; i < NUM_ELEMENTS; ++i) {cin >> runTimes[i];} /* Your solution goes here */ return 0;} Please help me with this problem using c++.

Problem 1 – Adding contactsIn this problem, you will create the skeleton for your entire assignment. In the next problems, you will add more functionality to your program.Our goal on this problem is to create a Rolodex to store names and e-mails (using 1D or 2D arrays, you can choose). The Rolodex can store up to 256 contacts. The Rolodex will store the contact's name as one String and the contact's e-mail as another String.Your application will work as follows:1. Upon starting, it will greet the user and prompt the user to select an option (an integer)2. There are three options in problem 1:1 – to add contactnote: If the Rolodex is full, i.e. there are 256 contacts stored, this option should print: "Roldex is Full" and ask the user to input a new option5 – to print all contacts0 – to exitIf the user inputs an incorrect value, the program should prompt for an option againIf the users select option 1:1. The application will then ask for the contact's name and e-mail (see the example for…

Shift Right k Cells  (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as:   [ 0,0,0,10,20,30 ]

For the array ADT, the operations associated with the type array are: insert a value in the array, delete a value from the array, and test whether a value is in the array or not. 1.true 2.false

In main: Declare an array capable of holding five Strings. Populate the array by entering five first names all on one one line separated by spaces (see sample output but use different names). Use a foreach loop (see page 255) to process the array and display the names on one line separated by spaces. Pass the array to a void method. In the void method: Sort the array. Create an arraylist of Strings. Use a loop to populate the arraylist with the Strings in the array that was passed it. Insert another name (you choose it) at the start of the arraylist. Remove the name at the end of the arraylist. Use a foreach loop to process the arraylist and display the names on one one line separated by spaces.

Shift Left k Cells   Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as:  [ 40, 50, 60, 0, 0, 0 ]

3. Implement a function called findLargestIndex which returns the index of the rowwith the largest sum.ex. int array[3][6] = {{3, 6, 8, 2, 4, 1}, // sum = 24{2, 4, 5, 1, 3, 4}, // sum = 19{1, 0, 9, 0, 1, 0}}; // sum = 11If the findLargestIndex function was called using this array, it would return 0, asit is returning the index of the row, not the sum.Note that the number of columns is required when passing a 2d array to a function.Assume that 2D arrays passed to this function will have 6 columns.Title line: int findLargestIndex(int array[][6], int rows, int columns);

This is needed in JAVA
