a. Write an application that prompts a user for a month, day, and year. Display a message that specifies whether the entered date is (1) not this year, (2) in an earlier month this year, (3) in a later month this year, or (4) this month. Save the file as PastPresentFuture.java.
b. Use the web to learn how to use the LocalDate Boolean methods isBefore(), isAfter(), and equals(). Use your knowledge to write a program that prompts a user for a month, day, and year, and then displays a message specifying whether the entered day is in the past, the current date,or in the future. Save the file as PastPresentFuture2.java.
Write an application to pre-sell a limited number of cinema tickets. Each buyer can buy as many as 4 tickets. No more than 100 tickets can be sold. Implement a program called Ticket Seller that prompts the user for the desired number of tickets and then displays the number of remaining tickets. Repeat until all tickets have been sold, and then display the total number of buyers.
Create a Java application which will take an infix algebraic expression as an input from user. It will check that whether it is a valid expression or not. Then It will be converted into postfix expression, and at the end it will be evaluated and print the result of the expression. For example:if input is: (3+5)*(7output: it is invalid.If input is: (3+5)*7 , displayPostfix form: 35+7*Answer: 56.

- Create an application in Java that uses card layout with three cards. The first card - a login card - should have two text fields, one for username and other for password. There are two users - Bob and Fred - whose passwords are "mubby and "goolag" respectively. If Bob logs in, switch to a card - the bob card - that has a text field, a text area and two buttons. If the first button is pressed, get the text from the text field and append it to the text area. If the second button is pressed, return to the login card. If Fred logs in, switch to a card - the fred card - that has three buttons. If the first button is pressed, change the background color to green. If the second button is pressed, change the background color to red. If the third button is pressed, return to login card.arrow_forwardWrite a program that lets the user play the slot machine (https://en.wikipedia.org/wiki/Slot_machine).A slot machine features a screen displaying three or more reels. To play, the user inserts money and activates the machine by means of a lever or button (either physical or on a touchscreen). The reels then spin and stop to rearrange the symbols. If the rearranged symbols match a winning combination, the player earns points based on a pay table. Symbols vary depending on the theme of the machine. Classic symbols include objects such as fruits, bells, and stylized lucky sevens.In this assignment, we slightly modify the operating mode of the slot machine as follows. Instead of the user manually activating the machine every time they want to play, the program will automatically play on behalf of the user multiple times. The user can choose from the following menu:1-> Play n times. The machine will repeatedly play n times.2-> Play until the credit gets below a minimum value.

The first asks you to think of a number between 1 and 10. The second displays a randomly generated number; the user can see whether his or her guess was accurate. (In future chapters, you will improve this game so that the user can enter a guess and the program can determine whether the user was correct. If you wish, you also can tell the user how far off the guess was, whether the guess was high or low, and provide a specific number of repeat attempts.) Save the file as RandomGuess.javaarrow_forward
- Task 5: ScanningMoney.java Write a program that reads User Input using the Scanner class. Your program should ask the user how many quarters, nickels, dimes, and pennies they have, then display the total amount in dollars. This can be done in main method.

- Help me modify my MaxSentinel Java Program(Attached image & Pasted Java Code) into a new program called MaximumSent... 1. Check for valid first entry. Then allow the user to enter as many numbers as desired. 2. If invalid number entered, print "Invalid entry." Prompt the user again until a valid number is entered. 3. Once -1 is entered, program stops and prints the largest number entered. Submit final code. JAVA CODE for MaxSentinel, has been pasted below: (also view attached images) import java.util.Scanner; public class MaxSentinel{ public static void main(String[] args) { Scanner input=new Scanner(System.in); int num=0,max=-1; System.out.print("Enter positive integers(-1 to stop):"); num=input.nextInt(); while(num!=-1) { if(num>max) max=num; System.out.print("Enter positive integers(-1 to stop):"); num=input.nextInt(); } System.out.println("Largest number: "+max); }}arrow_forwardCreate a java program that reads integers from the user until the enter key is pressed. Oncea allof the integers have been read your program should display all of the negativen numbers followed by all of the zeros, followed by all of the positive numbers. Withine eachgroup the numbers should be displayed in the same order that they were enteredbyt theuser. For example, if the user enters the values 3, -4, 1, 0, -1, 0, and -2 thenyourp programshould output the values -4, -1, -2, 0, 0, 3, and 1. Your programshould displaye eachvalue on its own line.arrow_forwardYou have been asked to develop the new system. You are to write an application to assign seats in an airline. Assume a small airplane with 28 seats (7 rows 4 wide) as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D 6 A B C D 7 A B CD The program should display the seat pattern, with an X marking the seats already assigned. 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D 6 A B C D 7 A B C D The program then requests a choice of seat. If the seat if available,then the seating display is updated. Otherwise, the program requests another choice of seat. If the user types in a seat that is already assigned, the program should say that that seat is occupied and ask for another choice. This continues until all seats are filled or until the user says that the program should end.arrow_forward
