- Java Write an application that allows a user to enter the names and birthdates of up to 10 friends. Continue to prompt the user for names and birthdates 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 birthdate or "Sorry, no entry for name" if the name has not been previously entered. The loop continues until the user enters ZZZ for a name.arrow_forward2.Create a visitors application that prompts the user for the number of visitors each day for the past 5 days and then displays the average number of visitors per day. (use & to accept new value) Use a for-loop for this question (1 to 5 , 5 iterations). The application output should look like same as following: Enter number of visitors on day 1: 150 Enter number of visitors on day 2: 220 Enter number of visitors on day 3: 180 Enter number of visitors on day 4: 300 Enter number of visitors on day 5: 320 The average number of visitors is 234arrow_forwardCreate an application that random 2 integers from 0 to 100.

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_forwardCreate a flowchart or pseudocode that allows for 10 digits. The input loop is paused at -1. The quit(sentinel) flag value of -1 does not exist in the array. The application then shows the sum and average of the entered values (excluding the -1). The application then shows the deviation from the mean for each value.arrow_forward1. first ask the user to enter the number of students in the range of 1 to 10. 2. then the program asks the user to enter the number of tests (in the range of 1 to 5) 3. Then use a loop to collect the scores for those many tests for each student. The outer loop will iterate once for each student. The inner loop will iterate several times, once for each test. Each iteration of the inner loop will ask the user to enter the score for a test of a student.arrow_forward

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 tells the 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. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.arrow_forwardWrite an application that counts by five from 5 through 500 inclusive and that starts a new line after every multiple of 50 (50,100,150 and so on).Save the file as CountByAnything.javaarrow_forward
- Question#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_forwardA Java Practical Assignments.pdf - Adobe Acrobat Pro DC (32-bit) File Edit View E-Sign Window Help Home Tools Java Practical Assig. x Sign In 1 /1 139% Java Practical Assignments 1.
