Question 3 : (Eliminate duplicates) Write a program Duplicate.java that reads in ten integers in an array T, creates a new array V by eliminating the duplicate values in the array, and displays the result. Here is the sample run of the program: Enter ten numbers: 1 2 3 2 1 6 3 4 5 2 The distinct numbers are: 1 2 3 6 4 5

Exercise #1: Cumulative sum: Write a Java program that prompts the user to enter an integer number (n) that indicates the number of elements of an array (the maximum value for n is 100). Then the user enters n double numbers. The program creates another array of cumulative sums of the first array and outputs it. One decimal place should be used to output the cumulative array. Sample inputs/outputs: Enter the array size: 4 Enter the array elements: 5.0 6.5 7.3 10.2 Cumulative Array: 5.0 11.5 18.8 29.0 Enter the array size: 101 The maximum size is 100! Enter the array size: 5 Enter the array elements: 2.34 5.61 4.67 0.897 Cumulative Array: 2.3 8.0 12.6 19.6 20.4

(1) Prompt the user to enter five numbers, being five people's weights. Store the numbers in an array of doubles. Output the array's numbers on one line, each number followed by one space. Ex: Enter weight 1: 236.0 Enter weight 2: 89.5 Enter weight 3: 142.0 Enter weight 4: 166.3 Enter weight 5: 93.0 You entered: 236.0 89.5 142.0 166.3 93.0 (2) Output the total weight, by summing the array's elements. (3) Output the average of the array's elements, with 2 decimal places. (4) Output the max array element.  Ex: Enter weight 1: 236.0 Enter weight 2: 89.5 Enter weight 3: 142.0 Enter weight 4: 166.3 Enter weight 5: 93.0 You entered: 236.0 89.5 142.0 166.3 93.0   Total weight: 726.8 Average weight: 145.36 Max weight: 236     Code: import java.util.Scanner; public class PeopleWeights {   public static void main(String[] args) {      /* Type your code here. */    }}

How do I write this code in java?

Part 2: Coding 1. Write a complete Java program named FindAverage that contains the following: a. A main method that asks the user to provide the number of rows and columns for a 2- dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printAverage method that will: i. Receive the two-dimensional array as input ii. Calculate the average of elements in this array iii. Display the average on the console. The average of all elements should be formatted as xxx.XX. Hint: you can print the 2D array at any point in the program using either traditional for loop, foreach loop or available methods in java.util package. e. Add comments to your program. Start your program with the following header: *** *** ***** /**** ***

python: numpy  def coupons(my_list, on_sale, prices):    '''    QUESTION 5    It's the time of week to go grocery shopping again!    Given three arrays, one of what's on sale, one of your own list, and one of the prices, return an array of the items on your list that are    on sale and more than five dollars. You have MORE coupons than you have groceries on your list- make sure to only use the coupons    that correspond to your list.     THIS MUST BE DONE IN ONE LINE    Hint: use masking and slicing     Args:        my_list(np.array)        on_sale(np.array)        prices(np.array)     Return:        np.array     >>> my_list = np.array(["eggs", "2% milk", "green onions", "whole wheat bread",                            "onions", "spinach", "peanut butter", "boxed spaghetti",                            "salt and vinegar chips", "alfredo sauce"])    >>> on_sale = np.array([True, False, True, True, True, True, False, False, False, True, False, True, False])…
