- Sorting objects in the real world https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html There are 5000 people living in the town. Every day they have new COVID-19 cases. When people show symptom, they go to the hospital and put themselves in the waiting list for testing. A new person is added at the end of the list. Due to the lack of testing kit, all in the list cannot be tested. Hospital has to sort them and select a few. Since the elderly is very weak to the COVID-19, every midnight the doctors sort the people in the list by their age to decide who is taking the test for the next day depending on the availability of testing kit. Input to the program has the form where the first line indicates how many days they will do the operation. For each day, the input starts with the day number, along with the following patient list where each element represents the name of patients and the age. The input ends with the number of available testing kits. The output display, at…A Student can be either a graduate student or an undergraduate student. A graduate student can be either a Masters or a PhD student. An undergraduate student can be an honour student. A department has both undergrad and graduate students. A department offers courses and each course is taught by a professor. Professors, Graduate students, and Honours students do research. Every person has a name. A student has ID. A department has location and a course has ID. Write java code for the above scenario. Each attribute should have a public getter and a public setter. You should use inheritance whenever possible. You have to override the toString operation in each class that defines an attribute. The overriden toString should print out the value of the attributes in the class. The research operation takes research subject as an input string and simply prints out the research subject. The Student class should have an arraylist of courses that the student takes, and an operation to add a…in java code: Simulate a forest fire. Complete the ForestFireSimulation class by implementing the nextStep() method that will perform the next step in the simulation. At each step, the fuel should be updated. This is done by decrementing the available fuel for a tree by 1. If there is no more fuel available, then the tree should be replaced with ash. Next, trees that are on fire can spread a spark to neighboring trees with a probability of spreadProb. Trees that have a spark should then be turned into a fire in the same step. The final action that needs to be completed in a step is setting new fires. Any tree can be ignited by lightning with a probability of lightningStrikeProb. getForestDensity, getSizeofFire and getFuelLevel should also be implemented in a reasonable fashion. import java.util.Random; public class ForestFireSimulation { public static final char TREE = '8'; public static final char SPARK = '.'; public static final char FIRE = '*'; public static final char ASH…

- Bomberman lives in a rectangular grid. Each cell in the grid either contains a bomb or nothing at all. Each bomb can be planted in any cell of the grid but once planted, it will detonate after exactly 3 seconds. Once a bomb detonates, it's destroyed — along with anything in its four neighboring cells. This means that if a bomb detonates in cell , any valid cells and are cleared. If there is a bomb in a neighboring cell, the neighboring bomb is destroyed without detonating, so there's no chain reaction. Bomberman is immune to bombs, so he can move freely throughout the grid. Here's what he does: Initially, Bomberman arbitrarily plants bombs in some of the cells, the initial state. After one second, Bomberman does nothing. After one more second, Bomberman plants bombs in all cells without bombs, thus filling the whole grid with bombs. No bombs detonate at this point. After one more second, any bombs planted exactly three seconds ago will detonate. Here, Bomberman stands back and…Bomberman lives in a rectangular grid.
