Please help me with this , I am stuck ! thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the all of the file: ArrayBag.cpp: #include <string>#include "ArrayBag.h" template <class T>ArrayBag<T>::ArrayBag() :…
c) Write a public static method getFirstD() with the following: o The method accepts 2 arguments: the first argument is an array of int, and the second is a value of int. The method returns a value of int type. o The method finds and returns the last element in the array which is divisible by the second argument, e.g. 8 is divisible by 4, but 9 is not divisible by 4. I The method returns your student ID number, if no divisible number is found in the array. Use a while loop to access the array elements. *NO more than 6 statement lines are allowed in the method body. YRIGH
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.
Note: It`s python coding 1. Class Implementationa) Implement a class Rectangle with two attributes, width and height.b) Implement an init method with an optional parameter type. Set the default value of the attributes of width and height to 1.c) Implement a display method to print the values of width and height.d) Instantiate two objects of type rectangle, one with arguments one without. r1 = Rectangle(4, 5) r2 = Rectangle()e) Call display() to print width and height.Example OutputWidth: 4Height: 5Width: 1Height: 1
Edit only the class definition. DO NOT CHANGE the code given under 'main' please. Steps: Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1. Support addition, subtraction, equality operations and the built-in abs function2. Are Iterable i.e., support for loops and star arguments for unpacking into function calls3. Support a string representation that displays the class name and coordinates stored by the instance: i.e. for an object initialized as: Vector(0, 3), the string representation should be ‘Vector(0, 3)’The code given under main tests for each of the program requirements and subsequently uses the turtle module to plot randomly generated points rotated. A screenshot for a sample run of the program is attached.

Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…

private float c; private void method2(double y) { c = y; } in another class we created an object of the first class then within in it : tester.method2 (10.0f); are there any errors ? how many errors if there are any and with explanation please.
Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.
