Exercise 1 - Number Guessing Game
Make a new Java Project called Lab2. Within it, add a new class with the main method called
NumberGuessGame. Inside the main method, implement a number guessing game, which will
work by generating a pseudorandom number in the range of 0 to 100 (inclusive, so both 0 and
100 should be possible), then asking the user to enter a number that will be their guess. If the
two match, display an appropriate message. Otherwise, display either "greater" or "lesser",
depending on whether the pseudorandom number is greater than or less than the number
entered.
Load your bag with some initial values, but do not fill it.
Your client code should give the user the option to:
display the contents of the bag using the class method “toVector”
add values to the bag
remove values from the bag
sort the bag
search for a value using their choice of either the iterative search or the recursive search - both need to be tested
Allow the user to keep doing these things until they are done.
Do not automatically sort the bag if the user chooses to search. Your program should give the user a message telling them they must first sort the bag before they can search.You decide what the user interface will be. Make it clear and easy to use. It can be very basic; nothing fancy. A menu driven program works well.
Each value in your array should be unique - no value will appear in the array multiple times.
Your array elements can be any data type – use a template class put in place in the code provided. You can write your client code to process a bag holding any…

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…arrow_forwardCreate another class TestCarwhich creates array of n number of cars, uses appropriate set methods to set the values of parametersof every car.

Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say so. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than oncearrow_forwardImplement the "Add player" menu option.
