- 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…The following technique is used in a game of chess: canMoveTo(int x, int y), boolean.

I'm not sure how to start After #6, I have other problems. Those are : 7.) Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Notes: This code requires a three-way selection statement and…
- 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.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. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):booleanCreate 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 See sample output below: Please enter 2 integers Please enter 2 integers 12 You entered 12 & 6. You entered 0 & 0. 12 + 6 = 18 0 + 0 = 0 12 6 = 6 0 - 0 = 0 | 12 * 6 = 72 O * 0 = 0 12 / 6 = 2 Both numbers are 0 and cannot be divided. Returning 0 | Please enter 2 integers You entered 6 & 0. 6 + 0 = 6 6. 0 cannot be used to divide by so cannot do 6 /0 |0 / 6 = 0
- 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.

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 JavaQ3. Modify the class by adding another method that prompts user for a positive integer. The program shall read the input as int; and print the "reverse" of the input integer. For example, Enter a positive integer: 12345 The reverse is: 54321 Hint: Use the modulo operator.
- Write the definition of a method that takes as input three numbers and returns the sum of the first two numbers multiplied by the third number. (Assume that the three numbers are of type double.)A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2. can you please write it in java.util.scanner form and can you make it so i can copy and past it thank you in advanceAll the animals are having a feast! Each animal is bringing one dish. There is just one rule: the dish must start and end with the same letters as the animal's name. For example, the great blue heron is bringing garlic naan and the chickadee is bringing chocolate cake. Write a method that takes the animal's name and dish as arguments and returns true or false to indicate whether the beast is allowed to bring the dish to the feast. Assume that beast and dish are always lowercase strings, and that each has at least two letters. Beast and dish may contain hyphens and spaces, but these will not appear at the beginning or end of the string. They will not contain numerals.
