- This is in Java, not sure where exactly I'm going wrong with this. Thanks in advance. (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. Example: Enter weight 1: 236Enter weight 2: 89.5Enter weight 3: 142Enter weight 4: 166.3Enter weight 5: 93 You entered: 236.0 89.5 142.0 166.3 93.0 (2) Also output the total weight, by summing the array's elements. (3) Also output the average of the array's elements. (4) Also output the max array element. Example: Enter weight 1: 236Enter weight 2: 89.5Enter weight 3: 142Enter weight 4: 166.3Enter weight 5: 93 You entered: 236.0 89.5 142.0 166.3 93.0Total weight: 726.8Average weight: 145.35999999999999Max weight: 236.0arrow_forwardCarry out the following task with an array: a. Allocate an arraya of ten integers. b. Put the number 17 as the initial element of the array. c. Put the number 29 as the last element of the array. d. Fill the remaining elements with –1. e. Add 1 to each element of the array.f. Print all elements of the array, one per line. g. Print all elements of the array in a single line, separated by commas.h. Count how many elements are less than a given value (entered by user). i. Remove all elements that are less than a given value (entered by user). j. Place all elements that are less than a given value (provided by user) in another array.arrow_forwardIt uses a one-dimensional array. You can refer to the PowerPoint slides, many of the tasks can be found there, but you need to apply them for this program. Note that the array will be filled with the integers when the user enters them. Consider the proper layout and correct indentation. Consider the following program that reads a number of nonnegative integers into an array and prints the contents of the array. You will add to the program. Complete the missing parts, add new function prototypes and function definitions, and test the program several times. Do not do it all at once. Add the following to the program: Write a function to display some heading with useful information which will display on the screen for the user. Write a void function that prints the list of nonnegative integers in reverse. Write a void function that prints all the numbers stored in the list that are greater than 10. It will also print the number of such numbers found. Write a function that determines…arrow_forward
- Can you help me with this code because i am struggling and I don't know what to do with this part: he Eight Puzzle consists of a 3 x 3 board of sliding tiles with a single empty space. For each configuration, the only possible moves are to swap the empty tile with one of its neighboring tiles. The goal state for the puzzle consists of tiles 1-3 in the top row, tiles 4-6 in the middle row, and tiles 7 and 8 in the bottom row, with the empty space in the lower-right corner. In this section, you will develop two solvers for a generalized version of the Eight Puzzle, in which the board can have any number of rows and columns. We have suggested an approach similar to the one used to create a Lights Out solver in Homework 2, and indeed, you may find that this pattern can be abstracted to cover a wide range of puzzles. If you wish to use the provided GUI for testing, described in more detail at the end of the section, then your implementation must adhere to the recommended interface. However,…arrow_forwardOkay, in my assignment I am not allowed to use array in the program. How do I replace what I have without the array?arrow_forwardDebugging challenge: Consider the code example below. This program is designed to compare the contents of two arrays: if they are equal, the program should display "TRUE," if the arrays are not equal, the program should display "FALSE". However, even when the arrays have the same value, the program always prints "FALSE", regardless of the values in arrays a and b. What is going on here? What about the program causes the comparison to always fail? int a[4] {1, 2, 3, 4}; int b[4] = {1, 2, 3, 4}; if (a == b) { display ("TRUE"); else { display ("FALSE");arrow_forward
- (YOU ARE NOT ALLOWED TO USE ARRAYLIST IN THIS PROJECT)Write a Java program to simulate a blackjack game of cards. The computer will play the role of the dealer. The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand.arrow_forwardHello! I need some help with my Java homework. Please use Eclipse Please add comments to the to program so I can understand what the code is doing and learn Create a new Eclipse project named so as to include your name (eg smith15 or jones15). In this project, create a new package with the same name as the project. In this package, write a solution to the exercise noted below. Implement the following method that returns the maximum element in an array: public static <E extends Comparable<E>> E max(E[] list) Write a test program that generates 10 random integers, invokes this method to find the max, and then displays the random integers sorted smallest to largest and then prints the value returned from the method. Max sure the the last sorted and returned value as the same!arrow_forwardIn this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…arrow_forward
- Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you…arrow_forwardCan you help me please: have the program know when numbers out of the array boundaries are received and mitigate those problems. The given code intentionally induces numbers out of bounds and the student’s portion must correct for this. As always use a header file and implementation file to do those calculations. Remember not to change the given code below in any way Design and implement the class myArray that solves the array index out of bounds problem and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements:myArray list(5); //Line 1 myArraymyList(2, 13); //Line 2myArray yourList(-5, 9); //Line 3The statement in Line 1 declares list to be an…arrow_forwardWe'll go over array notation writing in this part.arrow_forward
