- The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();}Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper limit.…Overloading is achieved when two or more methods in the same class have the same3.

- Dynamic Apex: Write test class for this apex code(Not required the output) You are working on the project in which you have to create the apex code in which your task is to define the objects dynamically by using the method argument which is api name in string and a map of string, string as a key value pair. Class Code: public static void modifySobjectData(String str , Map mapofString) { //Retrive the type of Sobject by using the getGlobalDescribe Schema.SobjectType targetType = Schema.getGlobalDescribe().get(str); //Initalize the Object Sobject newobject = targetType.newSobject(); for(String s :mapofString.keySet(O) { newobject.put(s, mapofString.get(s)); } System.debug('newObject' + newobject); //Perform the DML if(targetType != null) insert newobject; } }Please help write this in C++, I am kinda lost. bagDifference: The difference of two bags is a new bag containing the entries that would be left in one bag after removing those that also occur in the second. Design and specify a method difference for the ArrayBag that returns as a new bag the difference of the bag receiving the call to the method and the bag that is the method's parameter. The method signature is: ArrayBag<ItemType> bagDifference(const ArrayBag<ItemType> &otherBag) const; Note that the difference of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the difference of these bags contains x three times. Here is the all of the file: ArrayBag.cpp: #include <string>#include "ArrayBag.h" template <class T>ArrayBag<T>::ArrayBag() : itemCount(0) {// itemCount = 0;} template <class T>ArrayBag<T>::ArrayBag(const ArrayBag& orig) {itemCount =…USING C++ Random Number Guesser Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor.

I have written a NumberGuesser class to make things easier. // NumberGuesser.h #ifndef NUMBERGUESSER_H #define NUMBERGUESSER_H #include <iostream> class NumberGuesser { protected: int low; int originalLow; int high; int originalHigh; public: NumberGuesser(int l, int h) { low = originalLow = l; high = originalHigh = h; } virtual int getCurrentGuess() { return (high + low) / 2; } virtual void higher() { low = getCurrentGuess() + 1; } virtual void lower() { high = getCurrentGuess() - 1; } virtual void reset() { low = originalLow; high = originalHigh;…
- JAVA Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. Design a simple class and define a maximum method that finds the maximum of two integer values? Design an application to test that your new method is working properly. Now overload the maximum method to accept three double values and return the maximum of these three values? Finally overload the maximum method again such that it accept four double or four integer values and return the average of these four values? Modify your main( ) application to call and test these new methods. In each case the maximum overloaded methods should return the correct maximum values. Attach you java source codes and a screenshot of the output(s).using python language Suppose a call center has three levels of employees—respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design your own classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.hello! can you help debug my program? it's in Java! here are the errors I'm getting: line 189: total_weight cannot be resolved or is not a fieldline 93: the type Snake must implement the inherited abstract method Animal.makeNoise()line 139: the method actual_num_animals(int) is undefined for the type Zooline 152: the left-hand side of an assignment must be a variableline 169: syntax error, insert } to complete Blockline 152: syntax error, insert “. class” to complete expressionline 139: syntax error on token “<“, ( expectedline 139: syntax error on token “{“ invalid AssignmentOperatorline 152: i cannot be resolved to a variableline 152: i cannot be resolved to a variableline 154: i cannot be resolved to a variable here is my code: package zoo; public abstract class Animal { private String name; private double weight; private int age; public Animal() { name=""; weight=0; age=0; } public Animal(String name, double weight, int age) { this.name = name; this.weight = weight;…
- Can we have static methods in an Interface?True or False? Interface can be used to store a common method implementation.Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.
