Step by step
Solved in 2 steps
- Create a method that takes a value and indicate whether it is positive or negative by a return aBoolean value.Declared as: boolean isPositive (float a)Modify this class by: 1. Suppose the bank wants to keep track of how many accounts exist. A. Do you need a static variable or a regular variable to save how many accounts have been created? Declare it and name the variable as numAccounts. It should be initialized to 0 (since no account exists initially). B. Update this variable in the constructor. (Ask the instructor if you do not know how) C. Add a method getNumAccounts that returns the total number of accounts. Decide if this method should be static – is the information related to a single account or is it for the entire class? Does this method manipulate a static variable? Complete this method. 2. Use the driver class TestAccounts1.java to test your modified Account class. Complete the code as instructed. 3. Add a method void close() to your Account class. This method should close the current account by appending “CLOSED” to the account name and setting the balance to 0. Also, decrement the total number of accounts. Should this…In Java, all arguments are transferred to a method via value call (call by value)? Choose one of the options:TrueFalse
- Make a class that represents an average of test scores. Make the class take an unlimited number of scores and calculate the number of tests taken along with the average. Class name: TestScores Fields: - name : String - totalScore : double - numScores : int Methods: + TestScores(name : String) + addTestScore(earned : double) : void + getNumTestsTaken() : int + getAverage() : double Write in java and use test case 1 as an referenceIn the absence of any constructors, what will happen in Java? O Send out a cautionary note. Send out a message to the user indicating that something went wrong. Create a default constructor on the fly. O Create a constructor with an int return type on demand, rather than manually.List the name of this method and the name and type of its parameter:public void setCredits(int creditValue){ credits = creditValue;}
- Examine the method header below, then write a call to the method as an example.a personal void ValueReset (ref int value)Overloaded methodsA. Have the same nameB. Have different parameter types or numbers of parameters or bothC. Are distinguished by the types of values passed to themD. Have different return types Options: A and D are true. The others are optional A,B,C are true. D is optional Only A and B are true Only A is necessarily trueC# Given the following Deposit method, which can possibly overload it in the same class?public void Deposit() { } Question 8 options: public void Deposit(decimal amount) { } public void Deposit(int amount) { } public void Deposit(double amount) { } All of the above.
- Look through the method header below, then, as an example, write a call to the method.an internal void ValueReset (ref int value)Could you tell me how to fix the error in testing the following code: class Employee:""" The employee class has a constructor and getter methods.The constructor has input arguments"""# Assigns values for id, name, salary, and email from input argumentsdef __init__(self, i, n, s, e):self.id = iself.name = nself.sal = sself.email = e# getter function for namedef get_name(self):return self.name# getter function for IDdef get_id(self):return self.id# getter function for salarydef get_sal(self):return self.sal# getter function for emaildef get_email(self):return self.emaildef make_employee_dict(ids, names, sal, emails):"""Function to create employee object and the dictionaryusing those objects"""# k is the length of all the listsk = len(ids)emp_dict = dict()# Making employee object and adding to dictionaryfor i in range(k):e = Employee(ids[i], names[i], sal[i], emails[i])emp_dict[ids[i]] = e# return the dictionaryreturn emp_dict# Testingemp_names = ["Jean", "Kat", "Pomona"]emp_ids = ["100",…Allow the user to automatically flip a coin 500 times. Keep track of the number of times heads and tails appear. Also, keep track of "heads" winning streaks and "tails" losing streaks. That is, keep track of how many times 1 head in a row occurs, 2 heads in a row, 3 heads in a row and so on, and the same for tails. Be sure to separate all functions and methods (if you chose to use a class or structure) into both the prototype and an implementation below the main. 1. Write a regular c-type function that returns a random bool 1 = "heads" and 0 = "tails". Use the following prototype: bool coinFlip(void); 2. When the user plays the game, flip the coin 500 times automatically. Keep track of the number of "tails that come up", "heads that come up", the number of "heads" winning streaks as well as the "tails" losing streaks. The output may look something like this, where the code was only run 100 times: You flipped a coin 100 times:Number of heads = 54Number of tails = 46Heads winning…
