Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.
Create a new project named lab7_1. You will be implementing a Tacos class. For the class attributes, let’s use to type of taco, number of tacos, and price. Note that the price per taco of any type is 99 cents. Therefore, allow the taco type and number of tacos to be set directly, but not the price! The price should be set automatically based on the number of tacos entered. So a good idea may be to call the setter for the price inside the function that sets the number of tacos. Some other requirements: A default constructor and a constructor with parameters for your taco type and number of tacos member variables. You should also include setters and getters for these private member variables. However, make sure that the setter for price is private! You don’t want anyone outside the class modifying price. This setter should be called anytime you change the number of tacos. Your constructor needs to call a set method that allows you to set the two member variables, thus takes two…
Q1:Create a ticketing system using Java. this ticket system could be anything like booking movies or booking bus tickets. A user should be able to interact with the system and perform various actions on the records. Distinguish the operations on different types of tickets (general admission, reserved, front row etc.) Requirements: identify and implement at least five features/scenarios in your project, for example, purchase, refund, early bird, etc. please help me with this assignment.
Another functionality for the app is the ability to estimate the return on investment over a period of time. In order to implement this feature, you will have to update the investment calculator algorithm. The base function to calculate the return on investment from Task 1 can be reutilized here to simplify our task. This feature will take into consideration a 12-month period by default. To calculate the total amount earned over a period of time, you will have to loop through the n-months period, increase the amount for each period. The other rules from the previous task apply here as well. For example: If you invest $3 million on the first month, and obtain a return of $93,000 dollars, then the amount to be invested in the second month is $3.093 million. To summarize: Loop over a period of 12 months to calculate the total for each period Return the accumulated estimated value for a period of 12 months
Please help me create a cave class for a Hunt the Wumpus game. You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how room 1…

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "MinMax" (without the quotation marks) that declares an array of doubles of length 5, and uses methods to populate the array with user input from the command line and to print out the max (highest) and min (lowest) values in the array.
correct and detailed answer will be upvoted else downvoted. Output screenshot also required. understudies went to the primary gathering of the Berland SU programming course (n is even). All understudies will be partitioned into two gatherings. Each gathering will go to precisely one example every week during one of the five working days (Monday, Tuesday, Wednesday, Thursday and Friday), and the days picked for the gatherings should be unique. Besides, the two gatherings ought to contain similar number of understudies. Every understudy has filled an overview where they told which days of the week are advantageous for them to go to an illustration, and which are not. Your assignment is to decide whether it is feasible to pick two unique week days to plan the examples for the gathering (the main gathering will go to the illustration on the primary picked day, the subsequent gathering will go to the example on the second picked day), and gap the understudies into two gatherings, so…

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…
