Write a Java program that allows the user to enter the expenses’ in term of AED by using a while loop to calculate the average. The number of expenses is unknown. To stop entering the expenses, the user needs to enter a negative value. Show the total, average and the count.

A patient suffering from asthma needs to keep a diary of their "peak flow" breathing readings. This is just a number between 0 and 800 measuring how well they can blow air from their lungs. Their peak flow reading is the greatest of three readings taken at one time. Write a Java program to help the patient record their peak flow to show their doctor. The program should first ask the patient for the number their doctor has given them as being a dangerous reading. Any peak flow reading recorded that is less than the danger level should lead to a message that they need to go to hospital immediately. Once entered, this value should not be changed. After storing this number, the program should go into a loop that only stops when they type 0 instead of a day. It should repeatedly ask them for the day of the month which is a number from 1 to 31 (they may skip days) and then the three readings taken that day. All the peak flow readings (ie the largest of each set of three readings) should be…

Accumulating Totals in a Loop Summary In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. 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   Ensure the file named LeftOrRight.java is open. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking Run and using the data listed above and verify that the output is correct.

Write a java program that uses while loops to perform the following steps: a. Prompt the user to input two integers: firstNum and secondNum. (firstNum must be less than secondNum.) b. Output all the odd numbers between firstNum and secondNum inclusive. c. Output the sum of all the even numbers between firstNum and secondNum inclusive. d. Output all the numbers and their squares between 1 and 10. e. Output the sum of the squares of all the odd numbers between firstNum and secondNum inclusive. f. Output all the uppercase letters.
