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.

PLEASE WRITE IT IN C++ 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 main file: #include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std; template…
- Class Utilities { Method Details addDelimiter: public static java.lang.String addDelimiter(java.lang.String str, char delimeter) Returns a string where characters are separated by the specified delimeter character. A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - delimeter - Returns: String with characters…PROBLEM STATEMENT: Return the factorial of the provided integer parameter. public class FactorialComputation{public static int solution(int n){// ↓↓↓↓ your code goes here ↓↓↓↓return 0;} Can you please help me with the question above the Language is Java and can yiu use the java code that i gave above to answer the question1- question Given the following method; public static void mystery(int x) { int z = 10; if (Z <= x) Z--; z++; System.out.println(z); } What is the output of mystery(30)? a. 9 b. 10 C. 29 d. 30
- Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…Program to compute interest = p * r * t, where p = $10K, rate = 6%, t = 10 years; these values are to be passed from main() Besides main() the program has two methods: one that computes the interest and on that rounds interest to two decimal places public class DisplayInterest public static void main(String[] args) call a method that will do the computation with values for the above variables; with the exception of year, they are double main() displays computed interest after rounding computation method() rounding method() Note:- Please type and execute this java program and also need an output for this java program.Given the following: #includ int a[] ={4, 6}, i = 0, y =3, z =1; void f(int x){ int z = 2; g (); X = x + y; z = z +X; i++; return x + a[ i ]+y; } void g(){ z += 3; y = a[i] + z; } void main(){ printf("%d", y + f( a[i] ) - y); } State the output assuming the following: A) Call by reference, dynamic scoping, operands are evaluated right to left. B) Call by name, static scoping; operands are evaluated left to right.
