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.

Class: DoubleMethod Write a method using the header below public static double readDouble(String prompt) that displays the prompt string, followed by a space, then reads a floating-point number from the user, and returns it. Here is a typical usage: salary = readDouble("Please enter your salary:");percentageRaise = readDouble("What percentage raise would you like?");Write a test program to test the method.
JAVA Write a class that calculates add, subtraction, and multiplication. The class should include the following methods: Constructor : initialize all values to 0 getAsk() : Ask users to input two integer numbers. This method calls Distribute() method. Distribute() : Ask users to choose which calculation he/she wants. This method calls a method that can add, subtract, or multiply based on the user's option. CalAdd() : add two numbers CalSub() : subtract two numbers CalProduct() : multiply two numbers toString() : toString method that display result of operation. The program should be designed to test the class developed. Your program might look like the following: public class CalculateNumTesting{ public static void main(String[] args){ CalculateNum calculation = new CalculateNum(); calculation.getAsk(); System.out.println(calculation); } }
