Consider the following method: public static void sketch(int x1, int y1, int x2, int y2, int n) ( if (n <= 0) O else ( } drawLine(x1, y1, x2, y2); Assume that the screen looks like a Cartesian coordinate system with the origin at the center, and that drawLine connects (x1,y1) to (x2,y2). Assume also that x1, y1, x2, and y2 are never too large or too small to cause errors.

Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. How about we characterize a casualty substance: a casualty has a name (not really extraordinary) that comprises just of lowercase Latin letters and an integer doubt esteem. Toward the beginning of the program the client enters a rundown of n casualty names into an information base, every doubt esteem is set to 0. Then, at that point, the client makes questions of two sorts: 1 I x — set the doubt worth of the I-th casualty to x; 2 q — given a string q observe the most extreme doubt worth of a casualty whose name is a coterminous substring of q. Just to remind you, this program doesn't eliminate individuals, it just assists with looking for the names to record in a genuine scratch pad. Consequently, the rundown of the casualties in the data set doesn't change all through the questions. What are you sitting tight for? Compose that program now! Input The main line…

Rearrange the code below to provide two additional CashRegister methods: an enterPayment method that reduces the total price by the given payment, and a giveChange method that returns the change due and resets the total price and item count. Not all lines are useful.
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…

java program
A cashier in a supermarket returns change to customers. Suppose we want to write a program to help the cashier finding the possible combinations of coins that sum up to the change. Assume that the coin units available are 1, 2 and 5 Dollars where there is infinite supply of every coin. Write a method that receive the amount of change to be paid to the customer and then Prints the different combinations by which the change can be paid to the customer. Write a program to test this method. Example: if the change is 7 then the different combinations are: 1 1 1 1 1 1 1, 1 1 1 1 1 2, 1 1 1 2 2, 1 2 2 2, 1 1 5, 2 5,
