Implement the main method below in a class called Grade. The program should read integer points (use the Scanner class) and print the grade ("A", "B", "C", "D", or "F") based on the final score associated with a student. Grades are classified as follows:

Need help with this java problem. Some Websites impose certain rules for passwords.Write a method that checks whether a string is a valid password. The method must takes a password as a parameter and return a boolean value. If the password is valid, returns true, otherwise, return false. Suppose the password rules are as follows:- A password must have at least eight characters.- A password must contain only letters and digits.- A password must contain at least two digits. Please make sure you write a comment line to document what your method does. Write a program that prompts the user to enter a password, then call the method that checks the password, and displays "Valid Password" if the rulesare followed, or Invalid Password otherwise. The main program must allow the user to check multiple passwords. It should ask the user "Do you want to continue checking anther password (y/n)?"

You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design. MAIN CLASS: import java.util.ArrayList; public class Main { public static void main(String[] args) { System.out.println("Unit07Project2 by Your Name"); System.out.println(); int size = 10; School onw = new School(size); /* Add the code...

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...

In this assignment you will demonstrate your knowledge of debugging by fixing the errors you find in the program below. Fix the code, and paste it in this document, along with the list of the problems you fixed.This example allows the user to display the string for the day of the week. For example, if the user passed the integer 1, the method will return the string Sunday. If the user passed the integer 2, the method will return Monday. This code has both syntax errors and logic errors. Hint: There are two logic errors to find and fix (in addition to the syntax errors).Inport daysAndDates.DaysOfWeek;public class TestDaysOfWeek {public static void main(String[] args) {System.out.println("Days Of week: ");for (int i = 0;i < 8;i++) {System.out.println("Number: " + i + "\tDay Of Week: " + DaysOfWeek.DayOfWeekStr(i) )}}}package daysAndDatespublic class DaysOfWeek {public static String DayOfWeekStr(int NumberOfDay) {String dayStr = ""switch (NumberOfDay) {case 1:dayStr =...

You will build a program to manage a race car in this assessment. The code will consist of a for-loop method that will run a car around a race track and cause "wear and tear" on the car. The car will perform x number of laps and will have to make pitstops when it either runs out of gas or needs a tire replacement. The for loop will be simple def wear_tires(car): tire -=1 def use_gas(car): gas -=1 c = Car() # You need to make this part for i in range(100): if the car needs a pitstop: perform pitstop else: wear_tires(c) use_gas(c) # Display the current cars wear in a much better format print(c.tire) print(c.gas) print("Current Lap is: " , i) For this task, you will have to use this for loop and build out the two methods in the main Python program. To use the above code, you must build two pieces of information. An abstract Vehicle class A Car class A RaceCar class Each with its methods and variables. This programming will involve using inheritance and abstraction to make a race car...

We will rewrite the Sales Bar Chart question to use method for printing out the bar chart. The part where the asterisks are printed out should be done with a method. Use this method for each bar. The original question statement is here: Write a program that asks the user to enter today’s sales for five stores. The program should display a bar chart comparing each store’s sales. Create each bar in the bar chart by displaying a row of asterisks. Each asterisk should represent 100ドル of sales. Here is an example of the program’s output: Enter today's sales for store 1: 1000 [Enter] Enter today's sales for store 2: 1200 [Enter] Enter today's sales for store 3: 1800 [Enter] Enter today's sales for store 4: 800 [Enter] Enter today's sales for store 5: 1900 [Enter] SALES BAR CHART Store 1: ********** Store 2: ************ Store 3: ****************** Store 4: ******** Store 5: *******************

Wrtie TWO methods pass number of birds and print number of birds in California (method1) and birds in Texas (Method 1) Print the total of birds. You can use void method.

Program63.javaWrite a program that estimates the cost of carpet for one or more rooms with rectangular floors. Begin by prompting for the price of carpet per square yard and the number of rooms needing this carpet. Use a loop to prompt for the floor dimensions of each room in feet. In this loop, call a value-returning method with the dimensions and carpet price as arguments. The method should return the carpet cost for each room to main, where it will be printed and accumulated. After all rooms have been processed, the program should display the total cost of the job.Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
