A Java for loop has the following general form:
for(start; test; increment)
{
statements
}
in the parentheses after the keyword "for", _____ provides the starting point for the loop, _____tells what to adjust before the next loop iteration, and _____ is a boolean expression that when true, lets the loop to continue and when false, causes the loop to terminate.
• 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

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.

1. Write an application that throws and catches an ArithmeticException when you attempt to take the
square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on
it. The application either displays the square root or catches the thrown Exception and displays an
appropriate message.
2. Create a program that allows a user to input customer records (ID number, first name, last name,

- Using a Sentinel Value to Control a while Loop Summary In this lab, you write a while loop that uses a sentinel value to control a loop in a Java program that has been provided. You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the file named MovieGuide.java is open. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop to calculate the average star rating. Execute the program by clicking Run. Input the following: 0, 3, 4, 4, 1, 1, 2, -1 Check that the average…arrow_forwardUsing a Counter-Controlled whileLoop Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions Ensure the file named Multiply.java is open. Write a counter-controlled while loop that uses the loop control variable to take on the values 0 through 10. Remember to initialize the loop control variable before the program enters the loop. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. Execute the program by clicking Run. Record the output of this program.arrow_forwardMicrosoft Visual C# 7th edition. need help, please.

For example, if Y is input, output Y is not a valid code, and re-prompt the user until a valid code is entered. After data entry is complete, display a count of each type of mural. For example the output should be in the following format with the correct number next to each mural type: The interior murals scheduled are: Landscape 1 Seascape 2 Abstract 1 Children's 3 Other 9 The exterior murals scheduled are: Landscape 4 Seascape 0…arrow_forward
- Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tellsthe ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not.. Test your application with the following ticket numbers: - 123454; is a valid ticket number - 147103; is a valid ticket number -…arrow_forwardIn Chapter 1 you created a program named Triangle in which you displayed a seven-line triangle pattern like the one in Figure 6-33 by using a series of println() statements.

Write your own MineSweeper game, using wxWidgets and C++. This game should consist of a 10 x 10 grid of buttons. When the game starts the buttons should all appear to be plain, until the user clicks the first button. Once the user clicks that first button, the game should load in the hidden mines. Then the first button the user clicked on should display the number that tells the user how many mines surround the first box in the grid that (s)he chose. The user should be able to play the game just like the normal MineSweeper game until either (s)he lands on a mine and the game ends, os until (s)he wins the game by revealing all the squares that do not contain mines. Make sure to use a 24 point font so the numbers are nicely visible. To submit your answer, please paste in all your Source Code into a Word document.

Continue to prompt the user for names and birth-dates until the user enters the sentinel value “ZZZ” for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birth-date or an error message if the name has not been previously entered.
