- Question 3 [CLO 1-3, PLO 1-2, C 2-3] [10] a) Describe the different types of code smell and what technique is being used to remove code smell from the code. b) Consider the following java code (method) compares 2 numbers and returns true if the first is smaller and false otherwise. Do you think there is bad smells in this code, if yes than identify its type, and write a new code by using refactoring approach to remove the code smell. public boolean min(int a, int b) { ifla > b) { return true; } else if (a =b) { return false; } else { return false; } }public class utils { * Modify the method below. The method below, myMethod, will be called from a testing function in VPL. * write one line of Java code inside the method that adds one string * to another. It will look something like this: * Assume that 1. String theInput is 2. string mystring is ceorge неllo, пу nane is * we want to update mystring so that it is неllo, пу nane is Ceorge */ public static string mymethod(string theInput){ System.out.println("This method combines two strings."); Systen.out.println("we combined two strings to make mystring); return mystring;Java coding question below: ***************************************************** (determining Big O) write a PerformanceTest class and compare the performance of mergesort and bubblesort. Use the following “PerfomanceTest” class example. Instead of the provided simpleLoop,method, use the mentioned sorting algorithms.A) Test with an unsorted array (call the random(n) method to create a random array)B) Test with a sorted array (call the sorted(n) method to create a sorted array) Example: Consider the time complexity for the following simple loop: for(int i= 1; i <= n; i++) k = k+5;The complexity for this loop is O(n). To see how this algorithm performs, we run the perofmanceTest class to obtain the execution time for n = 1000, 10000, 100000, 100000 public class PerfomanceTest{ public static void main(String[] args) { // getTime(100000); getTime(1000000);} public static void getTime(int n) { //int[] list = random(n);…
- Please use Python to write the code** in Java ** Suppose we have a set of car. Each car has a number of colors, number of places, dimension and power. According to the set of cad we can have three sets: sedan, sport and pickup truck.1. Write a java program using the previous description.2. Use the flowing concepts,: heritage, polymorphism, encapsulation (get and set method)19- java. Which of the following is a drawback of using recursion? It may be less efficient than an iterative version. It may have fewer lines of code than an iterative version. It uses lesser memory stack than an iterative version. It runs faster than an iterative version.
- Please help solve this with java i posted it before and got rejected :( Modify the Show class such that it implements the Comparable interface of java.lang. Remember to add the concrete type Show between <> when you implement Comparable. Note the syntax error that occurs and understand why it occurs. 2. Implement (override) the compareTo method in the Show class such that it compares the showsaccording to their rates: returns 1 if the first show’s rate is greater than the second, -1if the first show’s rate is less than the second, and 0 if they are equal. (First show is “this”, second show is o) 3. Define an interface named Ratable, that has the method updateRate as shown in the UML diagram, in a file named Ratable.java. 4. Modify the Show class such that it implements the Ratable interface. Note the syntax error that occurs in the updateRate method and understand why it occurs. 5. Modify the updateRate method in the Show class such that it returns a double value that represents…change Summation Integers problem to Finding the minimumproblem. Make sure you properly wrote/updated all text messages, method names,and math calculations.Hint: You can use java.lang.Math.min() method.Example: System.out.printf("The min of the integers %4d and %4d and %4dis %7d\n", a, b, c,d MinTest(a, b, c,d)); fix below code structurePlease code in java

(Select all that apply) We can use for loop and while loop in recursion. We solve a problem that depends on solving smaller occurrences of the same problem. We have high performance while using recursion rather than iteration. We have high performance while using iteration rather than recursion. Easy to implement the algorithm while using recursion but hard to find the time complexity. Easy to implement the algorithm while using iteration but hard to find the time complexity. Base case is a simple occurrence that cannot be answered directly. Recursive case is a more complex occurrence of the problem that cannot be directly answered, but can instead be described in terms of smaller occurrences of the same problem. We must have exact one base case and one recursive case. We must have at least one base case. We must have at least one recursive case.
