Problem:
Bugs are simple creatures that only know how to walk towards other bugs. Bugs maintain
information about their (x, y) position; by which it can tell if they are standing next to other bugs.
Watch the following video: bug movement.
Create a java project that simulate bugs movement. You need to write a class “Bug" that models a
bug moving along a straight line and it can turn to change its direction counterclockwise (i.e. 90
degree to the left; north → west → south → east → north). In each move, its position changes by
one unit in the current direction. Details of the "Bug" class is described below.
Your simulator should read information of an unknown number of “Bug" objects from an input
file called “Bugs.txt". Each line represents a bug and the initial position and facing direction of this
particular bug. Keeping the first bug position as a reference the simulator should move the second
bug next to the first bug forming a cluster and its final position and direction should be…

Overview
In this task, you should try using the Scanner class to read data from the keyboard. This data should be stored in variables in your program and then printed on screen.
Task
You should write a class called Story that should include a main method. This programs should create a fairy tale for a child. The program is based on a completed story, but some words must be replaced with such as the user may enter. The fairy tale you are going to based on are the following:
The little ant (1)
There was once a small, small ant that lived with its (2) and its (3) siblings in an anthill, by a large (4) in the forest. The little ant is called (1). For the most part, (1) and his siblings used to work on carrying (5) and (6) to the stack, but today it was (7), so (1) was free.
The words that are crossed out are the words that your program should ask the user for.
In total, there are seven entries the user must make. The program must save these entries in separate variables and then…
Kinetic energy is the measure of the work that an object does by virtue of its motion. It is best
illustrated by the formula:
KE = 0.5 mv²
Create a java class that will call a method that will compute for the kinetic energy.
Sample output:
Enter mass of an object: 54
Enter velocity of an object: 2.87
The kinetic energy of an object is: 222.40 joules
Note:
1. The result should be in 2 decimal places.
2. Apply the exception handling method.
3. SCREENSHOTS NOT ALLOWED!
4. Save your file as KineticPT.java.

- Python In this assignment, a game called treasure hunt will be written object oriented.There are 3 types of treasures in the game. Diamond, Emerald and Gold. Diamond is 100 points, Emerald 70 points and Gold is 50 points.There are thieves in the game that will prevent you from hunting for treasure. Encountering a thief they steal some of your treasure. You will randomly generate which thief will steal from which treasure and how much.At the beginning of the game, the player has no treasure. X, Y, Z and H will be randomly identified at the start of the game. Define X Diamonds, a random number between X -> 100-200.Let a random number be defined between Y Emerald Y -> 100-200.Define a random number between Z Gold Z -> 100-200.You will define H thieves. Let it be defined between H -> 5-20. It will collect these randomly selected treasures to the player.For example:1- Diamond2-Emerald3-Diamond4-Gold5-Thief (k = treasure to steal, n = how many pieces he can steal)6-Gold....

The program should be able to ask the user for the input string and should be able to display the number of numeric characters on the screen. For this exercise, you should create your class to handle the different operations. Remember that any input/output operations should be done in the main method while all calculations should be done inside the class. Remember that you need to apply encapsulation in your class.

- Instructor note: This lab is part of the assignment for this chapter. HINT: 1). The decision means how many times to flip the coin. 2). Use a random integer variable to indicate the head or tail in each toss. Java Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Ex: If the random object is created with a seed value of 2 and the input is: 3 the output is: Heads Tails Heads Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used…arrow_forwardJAVA Write an application to simulate the rolling of two dice. The application should use an object of class Random once to roll the first die and again to roll the second die. The sum of the two values should then be calculated. Each die can show an integer value from 1 to 6, so the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent.arrow_forwardAssignment: Dice Rolling Program Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.
