Write a program that reads in numbers from the user and outputs the information specified below.
Part One: Get Valid Input
Read in two integers from the user: a lower end of a range and an upper end of a range. Check if the numbers are valid (lower cannot be greater than upper).
If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values.
Part Two: Calculate the Sum
Use a loop to calculate the sum of all values from lower (inclusive) to upper (inclusive). Output the sum to the user.
Part Three: Analyze the Sum
Determine if the sum is even or odd.
Determine if the sum is positive, negative, or zero.
Output this information to the user.
Part Four: Calculate the Average
Calculate the average of all numbers in the range from lower (inclusive) to upper (inclusive).
Style and Additional Coding Requirements
code should compile
properly space and indent your code
follow Java naming conventions for variables (lower camel case with no…
Write a program that will print the message “I love computer science” 12 times. Use a while loop.
Instead of printing 12 times, ask the user how many times the message should be printed. You will need to declare a variable to store the user’s response and use that variable to control the loop.
Number each line in the output, and add a message at the end of the loop that says how many times the message was printed. So if the user enters 3, your program should print this:
_____________________________________
1 I love computer science
2 I love computer science
3 I love computer science
This message is printed 3 times.
Write a program that will print the message “Computer Science is cool” 10 times. Use a while loop.
Instead of printing 10 times, ask the user how many times the message should be printed. You will need to declare a variable to store the user’s response and use that variable to control the loop.
Number each line in the output, and add a message at the end of the loop that says how many times the message was printed. So if the user enters 3, your program should print this:
_____________________________________
1 Computer Science is cool
2 Computer Science is cool
3 Computer Science is cool
This message is printed 3 times.

- Write a program in Python that sums a series of (positive) integers entered by the user, excluding all numbers that are greater than 100. We are going to use a sentinel value (also known as a flag value) to control the loop. If the user wants to quit summing up numbers, the user will enter a (-1). The first line should print out a title that says something like “Practice 3: summing positive values entered by the user that are less than 100”. For this practice you only can use while loop as you don’t know how many numbers the user wants to enter. A sample output is below.arrow_forwardWrite a program using nested for loops that will print the table below exactly as shown: 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 You MUST use nested for loops to accomplish this. You MUST store the value printed in a variable. You cannot just print the values as a String like “10 11 12 13 14 ….” Questions What is the primary difference between how a while loop operates and how a do while loop operates? View the code below and indicate where each variable would have scope. (Circle all boxes for each variable in which that variable would be useable. class DoLittle { public static void main(String[] args) { int number =…arrow_forwardYou will select one of the problems below and create a program that uses nested selections to solve the problem.Do not use Boolean operators. Write a program that reads three edges for a triangle and computes the perimeter if the input is valid. Otherwise, display that the input is invalid. The input is valid if the sum of every pair of two edges is greater than the remaining edge.arrow_forward
- Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints: 0 1 2 3arrow_forwardWrite a program that asks the user to enter an integer number and checks whether the number is prime or not. Hint: A prime number (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 . . . ) is a natural number greater than 1 that has no positive divisors other than 1 and itself. To check if a number N is prime, divide it in a loop from 2 to N-1 for remainder. If remainder is never 0, then N is prime. For example, 23 and 47 are prime, but 12 and 27 are not.arrow_forwardWrite a program that will print the message “Computer Science is cool!!” 10 times. Use a while loop.2. Instead of printing 10 times, ask the user how many times the message should be printed. You will need to declare a variable to store the user’s response and use that variable to control the loop. 3. Number each line in the output, and add a message at the end of the loop that says how many times the message was printed. So if the user enters 3, your program should print this:arrow_forward
- Write a program that reads in a series of integer numbers, and determines how many positive odd numbers are among them. Numbers are read until a negative integer is given. Use DO-Loop with EXIT statement.arrow_forwardWrite a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example output for userNum = 40: 20 10 5 2 1 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 40, then with userNum = 2, then with userNum = 0, then with userNum = -1. See "How to Use zyBooks". Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message. 367012.2549490.qx3zqy7 1 import java.util.Scanner; 3 public class DivideByTwoLoop { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int userNum; 4 6. 7 8 userNum = scnr.nextInt(); 9. 10 V* Your solution goes here */ 11 12 System.out.println(""); } 13 14 }arrow_forwardWrite a program that prompts the user to enter a series of strings, but with each string containing a small integer. Use a while loop and stop the loop when the user enters a zero. When the loop has finished, the program should display: the number of user inputs (not counting the final zero input). the total of the integers in the strings entered. the average of the integers accurate to one decimal place.arrow_forward
