- Introduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece.…Please help me with this , I am stuck !

- . Create a testEmployees class. Do the following: Declare an array called arrEmp of 10 Employee type objects in the main method. Write a static method called fillArray() that receives the arrEmp array. Use a while loop to enter the information (type of contract) of a number of new employees. Quit input by entering the character X instead of the type of contract. For each employee create an object and save the object in the array. Return the array to the main method. Call the static fillArray() method from the main method. Write a static method called displayArray() to receive the array and display a numbered list of the information of the employees using a for-loop and the toString() method. Call the static displayArray() method from the main method. Write a static method called updateEmpCommission() to receive the array and update the commission of some of the employees as follows: Use a loop to update a number of employees' commission. Use a sentinel value -1 to…What type of information does the following method return? public static void methodRankPoints(double points) int double nothing object Which statement is correct? The while loop repeats a set of code while a condition is not met. The number of iterations required of a while loop is always known before the while loop begins. The while loop repeats a set of code while a condition is met. The while loop does not require code to be added to manage iteration during each loop. Which of the following statements is true with regard to java exceptions? A try block can be followed by multiple catch blocks. A program automatically terminates immediately after a catch block is executed. Only one try/catch block is allowed in a single method. A try-catch is required in all methods.True or False? Arrays cannot be passed as parameters, but must be used only in the main method.
- JAVA Include Code Comments create a public class named ArrayUtility In ArrayUtility class, create a public static method toString that receives an array of int's, a start string, a separator string and an end string. It returns a String starting with the start string, followed by the array elements separated by the separator and ending with the end string. create a public class named ArrayUtilityTest In ArrayUtilityTest class, create a public static method toStringTest that prints the results for the following 5 lengths of arrays, using different types of brackets and separators for each: empty, singleton, two elements, 5 elements and 20 elements. Call only this class in the main method and check the results. In ArrayUtility class, create a public static method equals that receives two arrays of int's and returns true if they have the same length and equal corresponding elements. In ArrayUtilityTest class, create a public static method equalsTest that prints the results for the….is a block of code which only runs when it is called A classs integer method loopCode a called method that takes two parameters, an array of double as reference type and a double value.

- JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.Load your bag with some initial values, but do not fill it. Your client code should give the user the option to: display the contents of the bag using the class method “toVector” add values to the bag remove values from the bag sort the bag search for a value using their choice of either the iterative search or the recursive search - both need to be tested Allow the user to keep doing these things until they are done. Do not automatically sort the bag if the user chooses to search. Your program should give the user a message telling them they must first sort the bag before they can search.You decide what the user interface will be. Make it clear and easy to use. It can be very basic; nothing fancy. A menu driven program works well. Each value in your array should be unique - no value will appear in the array multiple times. Your array elements can be any data type – use a template class put in place in the code provided. You can write your client code to process a bag holding any…Remove is a method that is defined.
