Define a Static method 'max' with return type as 'int' in class 'ProblemSolution' that take two numbers with type 'int'. Inside the 'max' method, compare the two numbers and return the maximum of the two numbers. Then, inside the 'main' method. Define two 'int' type numbers; the first number (num1) is equal to 5 and the second number (num2) is equal to 2. At the next line, call the 'max' method where its parameter input are the two numbers above, and assign the result of the method to the variable num3 (type 'int'). Finally, on the next line, print out -> "The maximum of " + num1 + " and " + num2 + " is " + num3 Output The maximum of 5 and 2 is 5 Where, There must be space between all the words and numbers. There should not any space after the last number
Write a method called drawDiamond() that outputs lines of '*' to form a Diamond with equal length diagonals. Method drawDiamond() has one parameter, an integer representing the diagonal of the diamond. Assume the diagonal length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Either drawTriangle or at least one of its helper methods must be recursive. Ex: If the input of the program is: 3 the method drawDiamond() outputs: * *** * Ex: If the input of the program is: 15 the method drawDiamond() outputs: * *** ***** ******* ********* *********** ************ *************** ************* *********** ********* ******* ***** *** * Note: the diamond is made up of a rightside up triangle and an upside down triangle. import java.util.Scanner; public class LabProgram { /* TODO: Write drawDiamond() method here. */ /* You can add other helper methods if needed…

Define a static void method, which receives as an parameter an array of salaries (of type double) and increases them as follows • salaries <$ 800 - by 10% • 800 <= salaries <= $1500 - by 5% • salaries over $1,500 - by 3% In the test function, define an initialized array of salaries and display it. Call the written method and display the array again.
Write a method checks if a given matrix is a unit matrix. An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s. The method should take a 2D array of integers as argument and return a Boolean which is true/false depending on whether the matrix corresponding to the 2D array is a unit matrix or not. Test the method in the ‘main’ method. For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.
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…
In Public Class, create a static void method called Info_AHW that takes 3 parameters - an int and two double. When the method is called, we pass along the age (A), then the height (H), and then the weight (W), which is used inside the method to print the person's age, then the height and then the weight. NOTE: The Print out must follow the output below Afterward, in the main method, get the User input using the Scanner class to get the three input - the int age, the double height and the double weight. Then, call your Info_AHW method and pass your arguments (age, height, weight) into that method. Hint: When getting the int input, use -> sc.nextInt(); When getting the double input, use -> nextDouble(); Input: 5 65.5 70.2 Output: Your age is 5 ; your height is 65.5 ; and your weight is 70.2 Note: -There is a single space between every word and semicolon -There is no space at the end
Assume that we want to swap the values of two integer -variables, a andb. To do this, we write a method public void swap(int i1, int i2){int tmp = i1; i1 = i2; i2 = tmp;}Then we call this method with our a and b variables:swap(a, b);Are a and b swapped after this call? If you test it, you will notice that they are not! Why does this not work? Explain in detail.
Define a method findEmployeeTax() that takes two integer parameters as a person's salary and the number of dependents, and returns the person's tax percent as a double. The tax percent is returned as follows: Salary ≤ 1 dependent 2 - 5 dependents ≥ 6 dependents < 450000 0.15 0.05 0 450000 - 824999 0.25 0.15 0.15 ≥ 825000 0.4 0.25 0.25 Ex: If the input is 425000 0, then the output is: 0.15 import java.util.Scanner; public class TaxFinder { public static double findEmployeeTax(int salary, int numDepen) { double i; if (salary < 450000) { if(numDepen <= 1) i = 0.15; else if (numDepen >= 2 && numDepen <= 5) i = 0.05; else if (numDepen >= 6) i = 0; } else if (salary >= 450000 && salary <= 824999) { if(numDepen <= 1) i = 0.25; else if (numDepen >= 2 && numDepen <= 5) i = 0.15; else if (numDepen >= 6) i = 0.15; } else if…
