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 a variable of int type called "year" and assign it with value "2020" //create a variable of boolean type, call it "expectedResult" and assign it with value "true" //Call the method isLeapYear() and pass "year" as an argument to it,store the result in a variable of boolean type called "actualResult" //Verify if the actual result is equal to the expected result using assertTrue() } // Test case to check if a year is not a leap year @Test public void testNotLeapYear() { //create a variable of int type,call it "year" and assign it with value "1900" //create a variable of boolean type, call it "expectedResult" and assign it with value "false" //Call the method isLeapYear() and pass "year" as an argument to it, store the result in a variable of boolean type called "actualResult" //Verify if the actual result is equal to the expected result using assertTrue() } //Do not modify this code // Method to check if a year is a leap year or not private static boolean isLeapYear(int year) { // Check if the year is divisible by 400 or divisible by 4 and not divisible by 100 return year % 400 == 0 || (year % 4 == 0 && year % 100 != 0); } }

In Java Write a Fraction class that implements these methods:• add ─ This method receives a Fraction parameter and adds the parameter fraction to thecalling object fraction.• multiply ─ This method receives a Fraction parameter and multiplies the parameterfraction by the calling object fraction.• print ─ This method prints the fraction using fraction notation (1/4, 21/14, etc.)• printAsDouble ─ This method prints the fraction as a double (0.25, 1.5, etc.)• Separate accessor methods for each instance variable (numerator , denominator ) in theFraction classProvide a driver class (FractionDemo) that demonstrates this Fraction class. The driver class shouldcontain this main method : public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); Fraction c, d, x; // Fraction objects System.out.println("Enter numerator; then denominator."); c = new Fraction(stdIn.nextInt(), stdIn.nextInt()); c.print(); System.out.println("Enter numerator; then denominator."); d = new...

Question 1 Change the code of the setTemps method to ensure that: - hour: must be in the interval 0>> time1.setTime (25,10,63)>>> time1 1: 11: 3 Call this method in _init_ also to correct the values if they are not correct. Add the following methods to the Time class: isBefore (t2) returns True if the time represented by self is before the time of t2, otherwise it returns False. duration (t2) returns a new Time object with the number of hours, minutes, and seconds between self and t2. Test your methods in the interpreter or in the main program>> t1 = Time(12,4,0)>>> t2 = Time(10,2,1)>>> t1.before(t2)>>>t2.before(12,45,2)>>> t1.before(t2) True False>>> t1.duration(t2)>>> t2.before(t1) 0:41:2

Imagine that the String toUpperCase method did not exist and you were asked to write one. You can't use the String toUpperCase method, but you can use methods on Character. Hint: There is a method Character.toUpperCase(char) which converts a char to uppercase. Hint: There is a method Character.toString(char) which converts a char to a String.

Image 1 is my code, and image 2 is how to calculate the score. i need to write 2 methods (Inalready wrote the method 3) Method 3: A method to collect the required patient information (age, zip code, insurance information, pain level, and temperature) and compute the priority score takes one Scanner parameter returns the computed score Method 4: A method to calculate the priority score of the patient (this method should be called in the method 3) takes five parameters, once for each patient feature returns the computed score

A getPaycheck method that implements the same method in the Employee class. Itcalculates the paycheck amount (m_hours ×ばつ m_hourlyWage) and returns the studentworker’s paycheck as a string in the following format (Note that the three fields areseparated by a hyphen, represented by the minus character. Do NOT add spaces beforeor after each hyphen. There are no commas in the number.):

Write the following two methods: computeDiameter: This method accepts the radius (r) of a circle, and returns its diameter (2*r; radius = 7.5). Declare all variables used here & initialize radius: Show method call: Write method code here: displayData: This method accepts two arguments: radius & diameter. The output should have appropriate messages on the screen. Show method call: Write method code here:

Choose the correct answer: You can pass in multiple parameters with different data types into a method. You can pass in only parameters with the same data type into a method. You can receive multiple return values from a method. You can receive a return value with multiple data types from a method.

Create a calculator program. Get 2 numbers from the user. Create a method that adds the 2 numbers. Create a method that subtracts 1 number from the other. Create a method that multiplies the 2 numbers. Create a method that divides one number by another. It is important to check that you are not dividing by 0 here. You should be calling these methods from the main method and printing out the answers from the main method. Create a method that uses the modulus to return the remainder and the language is Java

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...

Define the following methods: computeBaseArea() has one double parameter as a cylinder's radius. The method returns the area of the cylinder's base as a double. The area of the base is calculated by: ���� = � ∗ ������2 computeSurfaceArea() has two double parameters as a cylinder's radius and height. The method returns the cylinder's surface area as a double, and uses the computeBaseArea() method to calculate the cylinder's base area. The surface area is calculated by: ������� ���� = (2 ∗ ���� ����) + (2 ∗ � ∗ ������ ∗ h���h�) Click here for example Note: Use Math.PI for �. 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 public class CylinderCalculations { /* Your code goes here */ publicstaticvoidmain(String[] args) { Scannerscan=newScanner(System.in); doublecylinderRadius; doublecylinderHeight; cylinderRadius=scan.nextDouble(); cylinderHeight=scan.nextDouble(); System.out.println("Cylinder radius: "+cylinderRadius);...
