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.
Java Programming: Write a static method named urgentAndIncomplete. Write the method as if it is in Main.java (not part of the ToDoItem class). The method should: Accept three ToDoItem references as parameters, and Return an int. Count how many of the ToDoItems meet two criteria: A priority greater than 3 Not completed The method should return how many of the parameters meet these criteria. That will be either 0, 1, 2, or 3.
Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).
The Hal9000 has one constructor which takes a String parameter of a name of the crew member it is interacting with. It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter. Supply Javadoc for the constructor and all the methods

Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
Value-returning methods must pass parameters. -True or -False

True or False The versions of an overloaded method are distinguished by the number, type, and order of their parameters.
Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66
JAVA HELP please 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).
