10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9
1)Examine the above code that creates the array: a)How is the base type of the array specified? b)How is the length of the array specified? c)How many Strings are actually stored in the array after the array has been created? d)How is the base type of the ArrayList specified? e)How is the capacity of the ArrayList specified? f)What is the capacity of the ArrayList? g)What is the size of the ArrayList?
in C#, Visual Basic Write an app for Boston Airlines that allows a customer to reserve a seat on the airline’s only plane (capacity: 10 seats). Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message “Next flight leaves in 3 hours."
In Java Assignment 5B : Maze Game! 2D Arrays can be used to store and represent informationabout video game levels or boards. In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by “O”) at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection (“Left”, “Right”, “Up”, or “Down”). Based on these directions, you will try tomove the player.• If the location is valid (represented by “_”), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by “X”), you will tell the…
