Write a JAVA program to create an array of objects of a class student. The class should have field members id, total marks and marks in 3 subjects viz. Physics, Chemistry & Maths. Accept information(get input from user) of 3 students and display them in tabular form in descending order of the total marks obtained by the student

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…

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…

Write a program that uses two classes. The first class is called “dAta” and holds x and y coordinates of a point in 2-d space called p1. The second class is called “cOmpute” and holds an array of two pointers to the “dAta” class. The “cOmpute” class has a function, lOad(float x, float y, int n), which loads x and y coordinate data into the array at index n. It also has a function, sLope(), which computes the slope of the line connecting the two array data coordiantes. It also has a function, pRint(), which prints the slope result to the screen. Implement a divide by zero exception using throw in the sLope() nd/or pRint() function as appropriate. The exception should, when caught, print “Slope calculation error…” to the screen and exit the function. The program should load the array with some example points and print the slope to the screen using the class functions.
