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).
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);
}
}
Please use Java as programming language
Create a class named Commission that includes 3 variables: a double sales figure, a double commission rate and an integer commission rate. Create 2 overloaded methods named computeCommission(). The first method takes 2 double arguments representing sales and rate, multiplies them and then displays the results. The second method takes 2 arguments: a double sales figure and an integer commission rate. This method must divide the commission rate by 100.0 before multiplying by the sales figure and displaying the commission. Supply appropriate values for the variables. Test each overloaded methods.
