Java programming. A method signature for a method consists of all elements of the method except the body. That is, a method signature consists of the privacy, (non-)static, return datatype, method name, and formal parameters. Consider the ceiling method as an example. public static int ceiling (double num) { return num <= 0 ? (int) num: (int) num + 1; } The method signature of the ceiling method is the first line of the method: public static int ceiling (double num). In this example, we note that ceiling is static because it is a standalone method and does not require an object to invoke (since we are not acting on an instance of a class). For parts a - d, give the method signature described by the scenario. a) A method in class String that returns the reversed version of the current String. b) A method that returns the maximum of two given integers. c) A method that returns true or false if the input integer is an even number. d) A default constructor for class Table.

Correct and detailed answer will be Upvoted else downvoted. Thank you!

Create a UML class diagram of the application illustrating class hierarchy, collaboration, and the content of each class. There is only one class.  There is a main method that calls four methods.  I am not sure if I made the UML Class diagram correct. import java.util.Random; // import Random packageimport java.util.Scanner; // import Scanner Package public class SortArray{ // class name public static void main(String[] args) { //main method Scanner scanner = new Scanner(System.in); // creates object of the Scanner classint[] array = initializeArray(scanner); System.out.print("Array of randomly generated values: ");displayArray(array); // Prints unsorted array sortDescending(array); // sort the array in descending orderSystem.out.print("Values in desending order: ");displayArray(array); // prints the sorted array, should be in descending ordersortAscending(array); // sort the array in ascending orderSystem.out.print("Values in asending order: ");displayArray(array); // prints the…

Incorrect Question 4 Consider public class Species { } // fields private String name; private int population; private double growthRate; // constructor public Species () { } name = "No Name Yet"; population = 0; growthRate = 33.3; Which of the following is the best setter method for the population instance variable? public boolean setPopulation(int newPopulation) { } if (newPopulation>= 0) { } population = newPopulation; return false; } return true; public public void setPopulation (int newPopulation) if (newPopulation>= 0) { } population newPopulation; public void setPopulation (int newPopulation) { population } = newPopulation;

Define an Animal method that updates the time to complete a particular behavior based on its name. Choose one of the following from the above choices (A, B, C or D within the code): public class Animal {       // Other instance variables, constructors and methods     // omitted for brevity       // A     public void updateTimeTakenForBehavior(String behaviorName, int timeToComplete) {         for(int i = 0; i < this.behaviorList.length; i++) {             Behavior tempBehavior = this.behaviorList[i];             if( tempBehavior.getBehaviorName().equals(behaviorName)) {                 tempBehavior.setTimeToComplete(timeToComplete);             }         }     }       // B     public void updateTimeTakenForBehavior(String behaviorName, int timeToComplete) {         for(int i = 0; i < this.behaviorList.length; i++) {             Behavior tempBehavior = this.behaviorList[i];             if( !tempBehavior.getBehaviorName().equals(behaviorName) ) {…
