Write a program named GradeStats.java then implement the following method: public static int[] gradeStats(int[] arr) It accepts int array representing test grades for CISY432 then calculates and returns the following grade statictics: highest, lowest, average, number of grades that are greater than or equal to 70, the number of grades that are less than 70

Consider an array that stores the following sequence of integers:               10, 15, 20, 25, 30               Write a Java method that returns the sum of the integers stored in the array.  The array must be passed to the method as an argument.

Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false

Create the following program to demonstrate working with arrays in java. Your company pays its sales staff on a commission basis. Each employee receives $500 per week plus 6.5% of their sales. For example, a salesperson who sells $10,000 worth of products will get a salary of 500 + (10000 * .065) or $1150 for that week. You are given the task of creating a program to allow a manager to enter in the sales for 10 employees. (Store them in an array of course.) Then it should display the 10 sales amounts, the 10 salaries for this pay period, and the average salary. (Hint: There are a couple ways to approach this one, here are two ideas: (1) You could create a second array for the salaries and load it at the same time as you gather and store the sales, then loop through the salaries one to find the average, and then you have all the pieces to print. (2) Another solution would be to take in the sales, and then calculate the salaries on the print (which means you don't have to store them in a…

For Java. Create a program that can read N integer numbers, store them in an array and then use a method to calculate and return the average of all numbers. Refer to photo.

in java  Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. If the first element is less than the last element, then assign Boolean firstSmaller with true. Otherwise, assign firstSmaller with false. Ex: If the input is: 5 40 22 41 84 77 then the output is: First element is less than last element 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20     import java.util.Scanner;   public class UserTracker { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; int[] userCounts; inti; booleanfirstSmaller;   numVals=scnr.nextInt();   userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); }   /* Your code goes here */    if (firstSmaller) {            System.out.println("First element is less than last element");        }        else {            System.out.println("First element is not less…

Program to compute interest = p * r * t, where p = $10K, rate = 6%, t = 10 years; these values are to be passed from main()   Besides main() the program has two methods: one that computes the   interest and on that rounds interest to two decimal places public class DisplayInterest     public static void main(String[] args)     call a method that will do the computation with values for the above     variables; with the exception of year, they are double     main() displays computed interest  after rounding                      computation method()     rounding method()           Note:- Please type and execute this java program and also need an output for this java program.

for beginning java, here's my assignment " Write a program that ask the user to enter a list of positive scores until the user enters a negative score to terminate the input.  You need to store these scores in an array.   You can assume the maximum number of scores the user may enter is 50.  However, you need to keep track of the actual number of scores entered.  Write 2 methods: 1. calculateAverage(): this method takes the list of scores and return the average score. 2. countPerfectScores(): this method takes the list of scores and return the number of perfect scores (100). The main program reads the input and calls these methods and print the results. Please make sure you write a comment line to document what your method does."   Here is my code, " import java.util.Scanner;class Main {  public static void main(String[] args) {    Scanner sc = new Scanner(System.in);     // Start array for scores    int[] scores = new int[50];    int size = 0;     // Have user enter scores until…
