Create a class name AddAgain for do-while loop that asks the user to enter two The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.
Lap Timer Tool
Write a program ON PYTHON that asks the user to enter the number of times that they have run around a racetrack, and then uses a loop to prompt them to enter the lap time for each of their laps. When the loop finishes, the program should display the time of their fastest lap, the time of their slowest lap, and their average lap time.

Write a while loop that prints userNum divided by 4 (integer division) until reaching 2 or less. Follow each number by a space. Example output for userNum = 160:40 10 2 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 160, then with userNum = 8, 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.arrow_forwardCode in Java using Do-while Loop Write a program that accepts an integer input.

When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L.L.L. R. L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions 1. Ensure the file named LeftOrRight.java is open. 2. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. 3.
