Java How To Program (Early Objects)
- • Use a while loop • Use multiple loop controlling conditions • Use a boolean method • Use the increment operator • Extra credit: Reuse earlier code and call two methods from main Details: This assignment will be completed using the Eclipse IDE. Cut and paste your code from Eclipse into the Assignment text window. This is another password program. In this case, your code is simply going to ask for a username and password, and then check the input against four users. The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: • alpha-alpha1 • beta-beta1 • gamma-gamma1 • delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: "Login successful." Here are a couple of example runs (but your code needs to work for all four user-password combinations): Username: beta Type your current password: beta1 Login successful. Username: delta Type…arrow_forwardIn Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In this lab, you will add some more functionality to the program. Use loops to keep running the program until the user chooses the exit condition (9). When dividing, use a loop to validate user input, making sure the denominator (second number) is not zero. If the user enters a 0 for the second number, display an error message and keep prompting until a non-zero number is entered. 1) Add two numbers2) Subtract two numbers3) Multiply two numbers4) Divide two numbers 9) Exit program The program should: contain header comments as shown in class display a hello message before presenting the menu display the menu prompt user for selection echo the selection back to the user if the selection was invalid, display error message to user and then loop back to menu if the selection was valid, prompt the user for two numbers if the operation is division, and…arrow_forwardn is an integer variable.Write a while loop that prints integer numbers starting with n and dividing the number to 4 each time, while the new number is greater than 0.(Example: If n is 2077, it will print 2077 519 129 ...)Write only the statements to perform the above explained task, nothing else.Use while loop, don't use for loop.arrow_forward
- Write a loop that asks the user “Do you want to repeat the program or quit? (R/Q)”. The loop should repeat until the user has entered an R or Q (either uppercase or lowercase).arrow_forwardYou need to write a loop that will repeat exactly 125 times.

O while loop checks the condition before the loop begins, whereas the do-while loop executes the body at least once before checking the condition. O while loop is used for counter-controlled and do-while, is used for a sentinel loop. O while loop is used for selection controlled and do-while is used for an infinite loop. O while loop is used for endless controlled control and do-while, is used for counter-controlled loop. Save All Ans Click Save and Submit to save and submit.

- In the switch statement, we can use int type only for the control variables that are being tested in the loop condition. True Falsearrow_forwardTranscribed Image Text In this assignment, you will design a program in which you will ask the user to enter a number and use a while loop to see if the number entered by the user is a palindrome number or not. A palindrome number is a number which remains the same, even when the digits are reversed. For example: 121 is a palindrome number. 277 is not a palindrome number. Lab Procedure: 1. Prior starting of the work consider how to design the while loop: a. What would be the loop condition? b. What would be the stopping criteria? 2. Determine how to extract each digit. What are the variables and where to initialize the variables. 3. Test the application by hand-calculating several values and use the same values to validate the operationarrow_forwardPYTHON PROGRAMMING ONLY. Please provide explanation as well. Thank you. Write a while loop that lets a user enter a number less than 10. If the number inputted exceeds 10, print an error and ask for the number again, in which a user may enter the same or a different number. When the user inputs a valid number, the number should be incremented by 5, and the result assigned to a variable named sum. This loop should continue to iterate as long as the sum totals less than 50. When sum exceeds 30, it should print "Almost there..." until it reaches or exceeds 50. Once it does, print out "your final sum is (replace with final sum)". For example, if the sum is currently 45 and the user inputs 4, the program will not enter the loop again since the new sum will be 54 and should then print "your final sum is 45".arrow_forward
- write a for loop to prompt the user to enter a number from 0 to 255. if the user enters any other number outside this range, print the number is not valid and prompt again If the user enters= 0, then exit the loop.arrow_forwardQuestion#2. The distance a vehicle travels can be calculated as fallout: Distance = Speed * Time For example, if a train travels 60 miles-per-hour for three hours, the distance [raveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph far a three-hour time period, it should display a report similar to the one chat follows: Hour Distance Traveled 1 90 2 100 3 150 Input Validation: Do not accept a negative number for speed and do not accept any value les than 1 for time traveled.arrow_forwardWhich loop should you use in situations where you want the loop to repeat until the boolean expression is false, but the loop should execute at least once?arrow_forward
