- Write a java program to create a "Calculator Quiz-Test" application to perform addition of three random questions. When the program starts your application should display 2 random numbers ranging from 1-100 and ask the user to enter the addition of these 2 numbers (similarly you have to create 2 more sets of questions) and finally you should display the number of correct and incorrect questions and display the total marks as well. A correct answer will earn 10 marks and an incorrect answer will get - 5 (negative mark). When the program ends you should display the following, ) Number of correct and incorrect questions 2) Total marks obtained 3) The answer for all generated questions.write a program in python Write a program that will allow a student to enter their name and then ask them to solve 10 mathematical equations. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether their answer was right or wrong, and accumulate the right values. After the 10 questions are asked, calculate the average that was correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer. A function that checks to see if the answer is correct and accumulates the number correct. A function that calculates the…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 } }
- in java write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zero). the program should end with zero, display the average as a floating point number, and if the entire input is zero the program displays "no numbers are entered except 0"JAVA Write a program that allows a user to enter a series of numbers and displays frequency of each number. Implement the following: 1. The user can enter a maximum of 20 numbers or enter-1 to end the series (i.e. they can enter less than 20 numbers by entering -1) 2. Only numbers between 0-9 is allowed (or -1 ); if the user enters a number outside the valid input, inform the user and ask them to enter a valid number; keep repeating till a valid input is entered. Implement reading and validation of user input in a class "UserInput" - it should have a static method getNextNumber() that returns a valid integer. In your main program, use UserInput.getNextNumber() to read a valid input. 3. Display the frequency of each number in the output, in the following format Number: Frequency For example, if the user input is 0,0,1,2,2,4,5,8,8,8,9,9, -1 the output will be: 0: 2 1; 1 2: 2 3: 0 4: 1 5: 1 6: 0 7: 0 8: 3 9: 2FOR JAVA Write a program that asks user to enter a number until user enters -1. Then the program should display the sum of all entered numbers except for -1.
- In Java Write a program that generates two integers and prompts the user to enter the sum of these two integers. Revise the program to generate three single digit integers and prompt the user to enter the sum of these three integersJAVA Given an airplane’s acceleration a and take-off speed v, you can compute the minimum runway length needed for an airplane to take off using the following formula: length = v2 / 2 * a Write a program that prompts the user to enter v in meters/second (m/s) and the acceleration a in meters/second squared ( m/s2 ) , then displays the minimum runway length needed to take off. Here is a sample run: Enter speed and acceleration: 60 3.5 [enter] The minimum runway length for this airplane is 514.286For My Java class, this being my first programming class, I have been asked to complete the following to learn Loops. Next is arrays but I was hoping to get help understanding this first. Thanks 1-Design a program that asks the user to enter a series of positive numbers. The user should enter a negative number to signal the end of the series. After all the positive numbers have been entered, the program should display their sum. 2-The distance a vehicle travels can be calculated as follows: Distance = Speed x Time Design a program that asks a user for the speed of a vehicle in miles per hour and how many hours it has travelled (Assume the two values are integers). Your program should then use a loop to display the distance the vehicle has traveled for each hour of that time period. (For example, entering 50 mph and 4 hours should produce output like: Hour 1: 50 miles, Hour 2: 100 miles, Hour 3: 150 miles, Hour 4: 200 miles. ) 3-Design a program that uses nested loops to display a…
- In Java code Write a program that takes in an integer in the range 11-100 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical.in java write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zero).the program should end with zero, display the average as a floating point number, and if the entire input is zero the program displays "no numbers are entered except 0" enter integers ending with 0: 1, 2, -1, 3, 0 total is 5 average is 1.25 3 positive numbers 1 negative numberWrite an application in Java that asks the user to enter two integers, obtains them from the user and prints their sum, product, difference and quotient (division). Sample Run Enter first integer: 18 Enter second integer: 5 Sum is 23 Product is 90 Difference is 13 Quotient is 3 Note: The exact division of 18 by 5 is 3.6. However, assuming you are using only integer (int) variables in your program, then the integer division of 18 by 5 is 3. IMPORTANT. Follow the various style conventions we've discussed in class (variable naming, constants, spaces, etc) including putting comments in your program.
