TRUE OR FALSE
- An interface can contain defined constants as well as method headings or instead of method headings.
Step by step
Solved in 2 steps
- JAVA 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).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.In Java, you have the opportunity to either use a predefined function/method or write a user-defined function/method. In this discussion, provide at least three criteria that would be used to develop an appropriate method of your choice and the rationale behind the selection of these criteria. Then provide an example of your method declaration and return type.
- 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.FOR JAVA Part I Create a Company class that has at least three properties. Part II Write proper constructor and other methods required for the class (get & set, toString etc.) Part III Write at least 5 different methods considering the applications of Company class. Your methods must handle exceptions. Part IV Write a Test class and use the methods written in Company class.COM. In your own words, describe the difference between a method and an abstract method
- JAVA A company needs to develop an object-oriented library with a few Java classes forthe following task. Overall, they want the classes to model the geometric shapes and calculatetheir areas. These geometric shapes include Square, Rectangle, Circle, and Triangle.The above four shapes share common attributes such as name and color. The area of a shapecan be calculated by using a method area( ) which can be implemented only until the exactshape is known. Different shapes need a different area( ) method.1) Design a Java abstract class called Shape to model this situation, which will serve as a parentclass. Write its code;2). All the above shapes should be drawable by the users by calling the draw( ) method.Different shapes are drawn differently. You should design a Java interface named Drawableto provide this method for the shape classes to implement in their own ways. Write its code;3). Write the code for the four classes: Square, Rectangle, Circle, and Triangle.Note:• You should decide…Crete a program that implements at least 4 combination of method overriding and overloading. Decide which class to use to properly illustrate your solution.3. The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();} Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper…
- Defining two or more methods within the same class with same name but different parameters list is called: a. Method overloading b. Method overriding c. Polymorphism d. AbstractionJava Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.Q# Which of the following might have only method signatures? Group of answer choices 1. An interface 2. An abstract class and a concrete class 3. An abstract class 4. An interface and an abstract class 5. None of these, they all require the implementation. 6. A concrete class
