Solved in 2 steps
- It is possible to invoke a method without explicitly providing an argument into a parameter when a(n)__________ is given for it.When you call a method, you must include the ____________ required by the method.A method's type is also its _____________________. a. scope b. accessibility c. parameter type d. return type
- True or False _6. A method can return one value ___7. A method can call itself. ___ 8. A method can take more than one parameter. 9. A method can call another method which can call a third method. 10. To calculate the value of 2.53.5, you use the Java statement Math.pow(3.5, 2.5);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).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.
- In Python: Write a class named Pet, which should have the following data attributes: _ _name (for the name of a pet) _ _animal_type (for the type of animal that a pet is. Example values are 'Dog','Cat', and 'Bird') _ _age (for the pets age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: set_nameThis method assigns a value to the _ _name field set_animal_typeThis method assigns a value to the _ _animal_type field set_ageThis method assignsa value to the _ _age field get_nameThis method assignsa value to the _ _name field get_animal_typeThis method assignsa value to the _ _animal_type field get_ageThis method assignsa value to the _ _age field Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type and age of his or her pet. This data should be stored as the objects attributes. Use the objects accessor methods to retrieve the pets…Please answer these multiple choice questions 1) The new operator: allocates memory is used to create an object of a class associates an object with a variable that names it. All of the above. Answer: 2) A method that performs some action other than returning a value is called a __________ method. null void public private Answer: 3) The body of a method that returns a value must contain at least one _________ statement. void invocation thows return Answer: 4) A variable whose meaning is confined to an object of a class is called: instance variable local variable global variable none of the above Answer: 5) A variable whose meaning is confined to a method definition is called an/a instance variable local variable global variable none of the above Answer: 6) In Java, a block is delimited by: ( ) /* */ “ “ { } Answer: 7) In Java, call-by-value is only used with: objects primitive types this all of the above Answer: 8) The parameter this refers to instance variables local…If you write a class with no constructor whatsoever, the compiler will provide a(n) __________. a. default constructor b. constructor list c. parameterized method d. error message
- Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep trying..”). Use…Activities: I. Write the proper method declaration/ method call for the following (Javaprogramming) A method named IT that does not accept but returns an integer value ____________________________________ Call method IT ____________________________________ A method named CSIT that accepts an integer and returns a character ____________________________________ A method named CCMIT that accepts two integers and returns a double ____________________________________ A method named Pass_array that accepts an array and returns no value ____________________________________ Call method Pass_array sending array x to it ____________________________________ A method named max that requires two integers and returns an integer ____________________________________ A method named Test that accepts an integer and returns a boolean value ____________________________________A(n) __________ can have an uninitialized value passed into it, but it must be set to some value before the method it belongs to finishes executing. a. input parameter b. reference parameter c. output parameter d. default parameter
