Chapter 4, Problem 19STE
Write a better version of the method dateOK with three int parameters (Display 4.9). This version should check for the correct number of days in each month and should not just allow 31 days in any month. It will help to define another helping method named leapYear, which takes an int argument for a year and returns true if the year is a leap year. February has 29 days in leap years and only 28 days in other years. Use the following rule for determining if the year is a leap year: A year is a leap year if it is divisible by 4 but is not divisible by 100, or if it is divisible by 400.

Task 03: Read the concept of Binomial coefficient given in chapter-6. Write a method that
takes two parameters n and k and returns the value of Binomial Coefficient C(n, k).
For example, your function should return 20 for n = 6 and k = 3, and it should return 35 for n= 7 and k
= 4. ( confirm it through the Pascal's triangle as given below).

Create a class with a method. The method has to decide whether a given year is a leap year or not.
Note- A year is a leap year if:
• It has an extra day i.e. 366 instead of 365.
It occurs in every 4 year e.g. 2008, 2012 are leap years.
For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap
year. In those cases, we need to check whether it is divisible by 400 or not.

- Problem: To write the JUnit test cases for our methods, you need to create two test methods: testLeapYear: This method should test if the isLeapYear method returns true for a given leap year. For example, you can choose the year 2020 and verify if the method returns true for it. If it does, the test will pass. If it doesn't, the test will fail. testNotLeapYear: This method should test if the isLeapYear method returns false for a given non-leap year. For example, you can choose the year 1900 and verify if the method returns false for it. If it does, the test will pass. If it doesn't, the test will fail. --------------------------------------------------------------------------------------------------------------------------------------------------------- import static org.junit.jupiter.api.Assertions.assertTrue; import org.junit.jupiter.api.Test; public class LeapYearTest { // Test case to check if a year is a leap year @Test public void testLeapYear() { //create…arrow_forwardYou are responsible for adding the appropriate testing code to your main. a.

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 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: *******************arrow_forward
- The method convertVolume() has an integer parameter. Define a second convertVolume() method that has two integer parameters. The first parameter is the number of gallons and the second parameter is the number of pints. The method should return the total number of pints. Ex: If the input is 9 2, then the output is: 9 gallons yields 72 pints. 9 gallons and 2 pints yields 74 pints. Note: The total number of pints can be found using (gallons * 8) + pints. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class VolumeMethods { publicstaticintconvertVolume(intgallons) { returngallons*8; } /* Your code goes here */ publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intgallonsUsed; intpintsUsed; inttotalPints1; inttotalPints2; gallonsUsed=scnr.nextInt(); pintsUsed=scnr.nextInt(); totalPints1=convertVolume(gallonsUsed);arrow_forwardAdd a method called multiplesOfFive to the Exercise class. The method must have a void return type and take a single int parameter called limit. In the body of the method, write a while loop that prints out all multiples of 5 between 10 and limit (inclusive) on a single line. For instance, if the value of limit were 15 then the method will print: 10 15 You can use the printEvenNumbers method that is already in the Exercise class as an example to help you work out how to complete this method. In the main method of the Main class, add a call on the Exercise object to your multiplesOfFive method that prints the multiples of 5 between 10 and 25. Add a method called sum to the Exercise class. The method must have a void return type and take no parameters. In the body of the method, write a while loop to sum the values 1 to 10 and print the sum once the loop has finished. In the main method of the Main class, add a call on the Exercise object to your sum method. Check that it prints: 55 Add…arrow_forwardGive comment to explain the code.

- Allow the user to automatically flip a coin 500 times. Keep track of the number of times heads and tails appear. Also, keep track of "heads" winning streaks and "tails" losing streaks. That is, keep track of how many times 1 head in a row occurs, 2 heads in a row, 3 heads in a row and so on, and the same for tails. Be sure to separate all functions and methods (if you chose to use a class or structure) into both the prototype and an implementation below the main. 1. Write a regular c-type function that returns a random bool 1 = "heads" and 0 = "tails". Use the following prototype: bool coinFlip(void); 2. When the user plays the game, flip the coin 500 times automatically. Keep track of the number of "tails that come up", "heads that come up", the number of "heads" winning streaks as well as the "tails" losing streaks. The output may look something like this, where the code was only run 100 times: You flipped a coin 100 times:Number of heads = 54Number of tails = 46Heads winning…arrow_forwardImage one is my code, I wanted to make some change to the blue part's code. The code I written in red(see image 1) is the method to check that an integer has exactly 5 digits is provided for you (fiveDigits). You just need to call it appropriately in your code(the part in blue square)! Notice that the fiveDigits method returns a boolean - think carefully about how you should use this return type to reprompt the user until they enter a valid zip code. And I want the same output be like (see image 2) for the invalid zip code part: I should only reprompt the user with the message "Invalid zip-code, enter valid zip-code: " until they enter a valid zip code. Similarly, if the user enters an invalid pain level, you should reprompt the user with the message "Invalid pain level, enter valid pain level (1-10): " until they enter a valid pain level. For example（image2)arrow_forwardThis is what I have so far I am trying to calculate the tax as the TaxPayer's income (returned by its getIncome method) times a corporate tax rate of 21% (0.21). This is what I have so far. I also would like to save the variable in a double named tax. I am having trouble figuring out to call the TaxPayers income to multiply it by the tax rate.arrow_forward
- Write a method called average that accepts two integer parameters and returns their average as a double. Then write a second method that overloads the first method and takes 4 integers and returns average.arrow_forwardJava- Please don't change anything like method, don't use scanner. Do exacty the following way: Write a method named getSumOfRange that accepts two integer parameters min and max and returns the sum of the integers from min through max inclusive. For example, the call of sumOfRange(3, 7) returns 25, which is 3 + 4 + 5 + 6 + 7. If max is less than min, return 0. Note that getStartOfRange is declared public so that the unit test code can call it import acm.program.*; public class SumOfRange extends CommandLineProgram { public void run(){// You may put code here to help with your debugging,// but it isn't tested.} public int getSumOfRange(int start, int end){// Your code here.}}arrow_forwardYou are asked to write a Java method that receives the Information Systems Department plan for first year (CourseID, Course Level, Course Credit) and returns the plan updated as follow: - Course credits are multiplied by 1.5. - Levels are updated to 3 levels and courses are distributed among these three. After completing writing the code, you have to write a JUnit code testing your original code. It should include at least ten black and white test cases. Please explain why you selected these test cases and write assumptions if necessary.arrow_forward
