The Schedule class contains several courses. Each Course has a name, start time, and end time. The toString method for a Course should return a string containing the name, start time, and end time. For example, if the course is "Networking I" and it is held from 8am to 8:50am, the toString method for that course should return: "Networking I: 8am - 8:50am" The toString method for a Schedule should return "Your Schedule:" followed by all of the courses in the schedule. Below is an example showing what the Schedule's toString method should return if it contained five courses (Networking I, Database, Web Development, Java, and Yoga): "Your ScheduleNetworking I: 8am - 8:50amDatabase: 9am - 9:50amWeb Development: 10am - 10:50amJava I: 12pm - 12:50pmYoga: 1pm - 1:50pm" Include a Main.java to test your code

CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.

JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #2. Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is “Four score and seven years ago” the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen. Test Case 1 Please enter a string or type QUIT to exit:\nHello World!ENTERThere are 2 words in that string.\nPlease enter a string or type QUIT to exit:\nI have a dream.ENTERThere are 4 words in that string.\nPlease enter a string or type QUIT to exit:\nJava is great.ENTERThere are 3 words in that string.\nPlease enter a string or type QUIT to exit:\nquitENTER

Implement the class Character The role should be “primary” or “secondary” all other values are not acceptable. Considercapital and small letters variance. The gender should be “m” or “M” for male or “f” or “F” for female. The age should be a positive value. The giveRaise method increase the salary of a character by a given percentage with amaximum salary of 10000. The toString method returns a string that describes the character. For example: [Elisabeth Kane, female, 35, primary,4500$] 2) Implement the class Play A Play can have at most 20 characters. The real number of characters is registered in nbOfCharacters and is updated automaticallywhen a new character is added. AddCharacter method adds a new character to the characters array and updates thenbOfCharacters value. The attribute nbPlay keeps track of the number of Plays created. The toString method returns a string description of the play including name, genre and thenames of all the characters.Example: [The Opera…
Monty Hall Problem – Coding Lab In this lab, you will write a code that simulates the Monty Hall Game Show. Thegame host gives the participant the choice of selecting one of three doors. Twodoors has a goat behind them and one door has a prize. The set of choices arerandomized each round. The participant needs to select the door with the prizebehind it. When the participant selects a door, the game host reveals a door with agoat behind it. The game host opens a door (different from the one selected by theparticipant) that has a goat behind it. The participant is then given the option tochange their choice. When you run your code, the code would display a message prompting the user toinput their door choice, labelled as 1, 2, and 3. Then the code will display a doornumber (different from the one the user picked) with a goat behind it and ask theuser if they would like to change their choice. The code then displays a message onwhether the user guessed the correct door. The game then…
