- In Java Create a class WhileEvent3, write code that asks the user to enter a positive or negative number or 'x' 'X' to quit the program. When out of the loop the sum of all numbers entered is printed. READ THE USER'S input as String an not as integer.In Java Create a class DoWhileEvent3, write code that ask the user to enter a positive or negative number or 'x' 'X' to quit the program. When out of the loop the sum of all numbers entered is printed. READ THE USER'S input as String an not as integer. Use a do while loop.Write a Java program, GradeApp that reads a series of exam scores given as integers in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category, followed class average (as a percentage with 2 decimal place): Use the value -1 as a sentinel value to indicate the end of the input. (The -1 value is used only to end the loop. Please do not use it in the calculations.)
- This is the question: only using the "while loop" Write a java program which asks the user to enter name and age and calls the following methods: printName(): Takes name as parameter and prints it 20 times using a while loop. printAge(): Takes age as parameter and prints all the numbers from 1 upto age. Write a java program that will print first 10 multiples of 3 in a single line.Write a java program which asks the user to enter name and age and calls the following methods: a. printName(): Takes name as parameter and prints it 20 times using a while loop. b. printAge(): Takes age as parameter and prints all the numbers from 1 up to age. Please strictly follow the format.shoen below Note: any extra or missing space / line will lead to test failure. (The output should look like exactly as the example shown below and with the commas included in the last line and all numbers in same line too. Use import so we can put our own names and numbers.) Name: Andy Age: 10 Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy 1,2,3,4,5,6,7,8,9,10 class Main {public static void main(String[] args) {}}Write a JAVA program which consists of a single class called Calculator. This program will display a menu with the following options: (1) add, (2) subtract, (3) multiply, (4) divide (5) mod, and (6) do nothing. If the user enters something else, the program should display an error message. Otherwise, it should ask the user for two numbers.
- In Java please and enter code where it says " /* Your code goes here */" Write a while loop that prints all powers of 2 that are less than a given number n. For example, if n is 100, print 1 2 4 8 16 32 64. import java.util.Scanner;public class PowersOfTwo{ public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("n: "); int n = in.nextInt(); /* Your code goes here */ while (/* Your code goes here */) { System.out.print(/* Your code goes here */ + " "); /* Your code goes here */ } System.out.println(); }}Create a java program that reads integers from the user until the enter key is pressed. Oncea allof the integers have been read your program should display all of the negativen numbers followed by all of the zeros, followed by all of the positive numbers. Withine eachgroup the numbers should be displayed in the same order that they were enteredbyt theuser. For example, if the user enters the values 3, -4, 1, 0, -1, 0, and -2 thenyourp programshould output the values -4, -1, -2, 0, 0, 3, and 1. Your programshould displaye eachvalue on its own line.java Write an application that asks a user to type an even number or the sentinel value 999 to stop. When the user types an even number, display the message “Good job!” and then ask for another input. When the user types an odd number, display an error message, "x is not an even number", and then ask for another input. When the user types the sentinel value 999, end the program. The EvenEntryLoop program displays the proper message for each input. Checks Test CaseIncomplete Single even number input 2, 999, test 1 Test CaseIncomplete Single even number input 5, 999, test 2 Test CaseIncomplete Multiple mixed number input 13, 3487, 987, 1234, 999 import java.util.*; public class EvenEntryLoop { public static void main (String args[]) { // Write your code here } }
- Create a java program to allow a customer to order multiple pizzas in different sizes, crusts, and toppings in one order and display each pizza's details and price and order total to user. The program should initialize order total to 0 and ask user for number of pizzas in the order, and then use a for loop to count up to this number. Inside loop, ask user to pick size, crust, and toppings, and siaplsy this pizza's details and price, and then add the pizza price to order total. After the loop ends, display total number of pizzas user ordered and order total. Here is a sample pricing menu you can use: Small: $8, Medium: $12, Large: $16 Regular crust: No extra charge, Pan Crust: $2 extra, Stuffed Crust: $3 extra (You may charge different based on size or just charge same extra for all sizes, up to you) Toppings: double cheeses: extra $1, pepperoni: $2 extra, sausage: $2 extra, mushrooms: $1 extra, olives: $1 extra (You may provide more types of toppings at your prices)Write a java program named Fibonacci that prints the Fibonacci sequence of numbers. The first two numbers in the Fibonacci sequence are 1. Every other number in the sequence is the sum of the two previous numbers. Your program should prompt the user to enter a limit; the program will stop when the current number in the sequence is greater than or equal to this limit. Here's what the user will see when the program is executed: This program prints the Fibonacci sequence Enter a limit on the largest number to be displayed: 50 1 1 2 3 5 8 13 21 34Write a java program which asks the user to enter name and age and calls the following methods: a. printName(): Takes name as parameter and prints it 20 times using a while loop. b. printAge(): Takes age as parameter and prints all the numbers from 1 upto age. 2. Write a java program that will print first 10 multiples of 3 in a single line.
