Modify the Percentages application whose main() method holds two double variables. Assign values to the variables.
Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to “2.0 is 40.0 percent of 5.0.”
Then call the method a second time, passing the values in reverse order.
For testing use the values 2.0 and 5.0.
An example of the program is shown below:
2.0 is 40.0 percent of 5.0 5.0 is 250.0 percent of 2.0

- This assigment wants me to: Assume that a gallon of paint covers about 350 square feet of wall space. Create an application with a main() method that prompts the user for the length, width, and height of a rectangular room. Pass these three values to a method that does the following: Calculates the wall area for a room Passes the calculated wall area to another method that calculates and returns the number of gallons of paint needed Displays the number of gallons needed Computes the price based on a paint price of $32 per gallon, assuming that the painter can buy any fraction of a gallon of paint at the same price as a whole gallon Returns the price to the main() method The main() method displays the final price. For example: You will need 2.0 gallons The price to paint the room is $64.0 here is my code and this is all i have so far help please ! import java.util.Scanner; public class PaintCalculator { public static void main (String args[]) { int AreaPerGalllon =…arrow_forwarda - Create a FitnessTracker class that includes data fields for a fitness activity, the number of minutes spent participating, and the date. The class includes methods to get each field. In addition, create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Save the file as FitnessTracker.java. Create an application that demonstrates each method works correctly, and save it as TestFitnessTracker.java. b - Create an additional overloaded constructor for the FitnessTracker class you created in Exercise 3a. This constructor receives parameters for each of the data fields and assigns them appropriately. Add any needed statements to the TestFitnessTracker application to ensure that the overloaded constructor works correctly, save it, and then test it. c - Modify the FitnessTracker class so that the default constructor calls the three-parameter constructor.

- To encourage good grades, Hermosa High School has decided to award each student a bookstore credit that is 10 times the student’s grade point average. In other words, a student with a 3.2 grade point average receives a $32.0 credit. Create an application that prompts a student for a name and grade point average, and then passes the values to a method (computeDiscount) that displays a descriptive message. The message uses the student’s name, echoes the grade point average, and computes and displays the credit.
