- Java programming If we send an int parameter to a method, and the parameter value is changed inside the method, will that affect the original value?Retail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.Value-returning methods must pass parameters. -True or -False
- 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…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 variables global variables the calling object Answer: Pls answer these mcq's 9) When the parameters in a method have the same as instance variables you can differentiate them by using the _____ parameter. String hidden default this Answer:c# uppose there is a method called Current Deposit is your project class. The method header is as below: public static decimal Current Deposit( in years , decimal future, double rate) This method will return the current amount of money in an account if you pass the future amount, the annual interest rate, and years number. Write one statement to declare a decimal variable myMoney, call the method with the future amount $50,000.00, interest rate 8%, and 15 years, and assign the returned value to myMoney.
- basic java please Write a method dominant that accepts three integers as parameters and returns true if any one of the three integers is larger than the sum of the other two integers, otherwise it returns false. The integers might be passed in any order, so the largest value could be any of the three. If no value is larger than the sum of the other two, your method should return false. For example, the call of dominant(4, 9, 2) would return true because 9 is larger than 4 + 2. The call of dominant(5, 3, 7) would return false because none of those three numbers is larger than the sum of the others.True or False: The value of a local variable is retained between method calls.Writing Methods that Return a Value in Java In this lab, you complete a partially written Java program that includes a method that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, −, *, /,or% ). The two numbers and the operator are passed to the method where the appropriate arithmetic operation is performed. The result is then returned to the main() method where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3.00 * 4.00 = 12.00 The source code file provided for this lab includes the necessary variable declarations, and input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Write the Java statements as indicated by the comments.

Let the application toss a coin each time the user chooses the " Toss Coin " menu option. Count the number of times each side of the coin appears. Display the results. The application should call a separate method Flip that takes no arguments and returns false for tails and true for heads. [ Note: If the application realistically simulates coin tossing, each side of the coin should appear approximately half the time.]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).
