Write a java program: Question 1 Write a program that allows the user to enter name and grade until "QUIT" is entered for name. The grade should be a number between 0 and 100. If the user input of a grade is not in this range, you should ask the user to re-input the grade. Store all the names in an array called names, and all the grades in an array called grades. Print out all the names and the corresponding grades. For Example, Input Enter name: Alice Enter grade: 90 Enter name: Bob Enter grade: 80 QUIT Expected output Name: Alice, Grade: 90 Name: Bob, Grade: 80
In java Write a program that uses a 2-D array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and highest and lowest temperatures of the year. Your program must consist of the following methods with their appropriate parameters:a.) getData: This method reads and stores the data in the 2-D array.b.) averageHigh: This method calculates and returns the average high temperature of the year.c.) averageLow: This method calculates and returns the average low temperature of the year.d.) indexHighTemp: This method returns the index of the highest temperature in the array.e.) indexLowTemp: This method returns the index of the lowest temperature in the array.Use the following input:High temp for each month: 30 40 45 60 70 90 89 95 79 90 70 40Low temp for each month: 10 -10 20 30 50 75 85 79 50 80 30 20
For Beginners Java: 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.
Create the following program in java: Write a java program that lets a meteorologist record day and evening temperature for a certain number of days. The temperatures must be stored in a two-dimensional array. Your program should: · Ask the meteorologist the number of days he/she wants to record temperatures for. · Read the temperatures. · Report the number of days where both the day and evening temperature are below average. · The number of days where the difference between the day and evening temperature is less than 10. · The highest and lowest day and evening temperature.
Here you go Create a java program that generates elements (randomly from 10 – 75) of a 2-dimensional array (5x5) using the Random Class then perform the following:1) Output the array elements2) Output the sum of prime numbers in the array3) Output the elements in the main diagonal.4) Output the sum of the elements below the diagonal.5) Output the sum of the elements above the diagonal.6) Output the odd numbers below the diagonal.7) Output the even numbers above the diagonal. NOTE: Please do not use the array methods available on the internet. Use the for loop, while loop or do-while loop statement in your codes..
for java please Please submit the pseudocode of your program for your project below. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final average or grade. I would like the system…
in Java please This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team. (1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99, but this is NOT enforced by the program nor tested) and the player's rating (1 - 9, not enforced like jersey numbers). Store the jersey numbers in one int array and the ratings in another int array. Output these arrays (i.e., output the roster) as shown below after inputting the data. Ex Enter player 1's jersey number: 84 Enter player 1's rating: 7 Enter player 2's jersey number: 23 Enter player 2's rating: 4 Enter player 3's jersey number: 4 Enter player 3's rating: 5 Enter player 4's jersey number: 30 Enter player 4's rating: 2 Enter player 5's jersey number: 66 Enter player 5's rating: 9 ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 . . . (2) Implement a menu of options for a user to modify the roster. Each…
9. Complete a program in a class ToyCounter that computes the cost of toys sold in a shop. Five kinds of toys-Zen, Leo, Star, Sam, and Barry-are stocked and cost, respectively, RM0.75, RM0.50, RM1.25, RM0.80 and RMO.75 per toy. Create an array of strings that holds the names of these toys. Create another array that holds the cost of each corresponding toy. Your program should read the name of a toy and the quantity desired by a customer. Locate the toy in the name array and use that index to find the cost from the cost array. Compute and print the total cost of the sale as output in Figure 8 below: E Output - test (run) #4 x :unz What kind of£ toy would you like? zen How many toy would you like? 10 zen: 10 at RMO.75 will cost RM7.5 Figure 8 Insert your answer here (Figure 9): import java.util.Scanner: public class ToyCounter public static void main (String [] args) double totalcost; int number; String() toyName - {"zen", double [] prices = (0.75, 0.50, 1.25, 0.80, 0.75): "leo", "star",…
Write a program that lets the user enter the total rainfall for each of 12 months (starting with January) into an array of doubles. The program should calculate and display (in this order): the total rainfall for the year, the average monthly rainfall, and the months with the highest and lowest amounts. Months should be expressed as English names for months in the Gregorian calendar, i.e.: January, February, March, April, May, June, July, August, September, October, November, December. Do not accept negative numbers for monthly rainfall figures. When a negative value is entered, the program outputs "invalid data (negative rainfall) -- retry" and attempts to reread the value. NOTE: Decimal values should be displayed using default precision, i.e. do not specify precision.
Write a program that does the following: • Reads an integer from the user that represents the number of the students in a class. • Reads the scores of the students from the user and stores them in an array. • Calculates and prints the average of the students with a passing grade (above or equal to 60). Hints: Assume that the scores of the students are integers between 0 and 100 (inclusive) • Assume that there is at least one student in the class with a passing grade. Using java Sample run 1: Enter the number of students in the class: 3 Enter the scores of 3 students: 90 80 40 The average of the students with a passing grade is 85.0 Sample run 2: Enter the number of students in the class: 5 Enter the scores of 5 students: 90 80 40 60 70 The average of the students with a passing grade is 75.0
HangmanAA.java For this program, you will create the game Hangman. (If you are unsure of how to play Hangman, Google it.) The game will start by asking player 1 for a word or phrase (can be multiple words). Then player 1 will be asked how many missed guesses are allowed by player 2. Once this information is received, player 2 will take over. (Have the program print many blank lines of space so that player 2 can’t see what player 1 entered.) The instructions should be displayed for player 2 as well as the number of misses they’re allowed to make before they lose the game. The screen should also output dashes or underscores to represent each letter of player 1’s secret word/phrase. Player 2 should guess one letter at a time. Case should not matter. Typing x or X should give the same result. If that letter is present in the mystery phrase, then it should be displayed. (It will replace the dash/underscore in that spot. Spaces, punctuation, and all other non-alphabetic characters should…
