This is wrong. Suppoeed to four method and call everything in main method. You can look at the question first.
.If the name of getBalance is changed to getAmount, does the return statement in the body of the method also need to be changed for the code to compile? Try it out within BlueJ. What does this tell you about the name of an accessor method and the name of the field associated with it?
i can't find the main method in this code , can you look at it please.

- Type the correct answer in the box. Spell the words correctly. How can you create a class without any methods, yet call a method from that class? The class can methods from another class.arrow_forwardPlease show work in javaarrow_forwardOverride the testOverriding() method in the Triangle class. Make it print “This is theoverridden testOverriding() method”. (add it to triangle class don't make a new code based on testOverriding in SimpleGeometricObject class.)

- Create a new project for this program called TestOldMaid and add a class with a main() method. In the project: Copy your Deck and Card class from the earlier project into it. Create a subclass of Deck called OldMaidDeck. It is special because one of the Queens is missing so it only has 51 cards. Create a constructor method that calls the super class constructor, then removes a queen. Override the toString method so it returns the name of the deck and the number of cards in it. Write the test main() method. Create an OldMaidDeck object and deal all the cards to six players. It is ok if not everyone has an equal number of cards. Use arrays or ArrayLists for the players hands. Show the hands of all 6 players. Refer to the web to find out more about the Old Maid card game: https://bicyclecards.com/how-to-play/old-maid/ Fully document all classes with your name, date and description. And each data member and method is documented. Each block that does something is also documented.arrow_forwardCreate a new project for this program called TestOldMaid and add a class with a main() method.

A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor. Your task is to add two fields: ● String name ● String rollNumber and provide getter/setters for these fields: ● getName ● setName ● getRollNumber ● setRollNumber Implement this class according to the rules of encapsulation. Input # Checking all fields and getters/setters Output # Expecting perfectly defined fields and getter/setters. There is no need to add constructors in this class.arrow_forward
- Add another public method called add() to TestFraction1 class. This method adds another fraction to the ‘calling object’. Thus, the method will take a Fraction class object as a parameter, add this parameter fraction to the calling object (fraction), and return a Fraction object as a result. HINT: we can use cross multiplication to determine the numerator of the resultant Fraction. The denominator of the resultant Fraction is simply the multiplication of the denominators of the two other Fractions. import java.util.Scanner;//test programpublic class TestFraction1{public static void main(String[] args) {//create a Scanner objectScanner in = new Scanner(System.in);//create new fractionFraction frac = new Fraction();//declare numerator and denominatorint n=1,d;System.out.print("Enter Fraction's Numerator: ");//input numeratorn = in.nextInt();System.out.print("Enter Fraction's Denominator: ");//input denominatord = in.nextInt();//loop execute until the numerator is…arrow_forwardShare at least three tasks that you know WinMain (starting) method handles.arrow_forwardRead the class Person to store the name a person we discuss in the class (source is Person.java attached in the assignment). As we can see that the methods we included merely set the name and print the name of a person. Redefine the class person so that, in addition to what existing Class does, you can Set the last name only. Set the first name only. Set the middle name. Check whether a given last name is the same as the last name of this person. Check whether a give first name is the same as the first name of this person. Check whether a given middle name is the same as the middle name of this person. Add the method equals that returns true if two objects contains the same first and last name. Add the method makeCopy that copies the instance of variables of a Person object into another Person object. Add the method getCopy that creates and returns the address of the object, which is a copy of another Person Object. Write the definition of the methods of the class Person to implement…arrow_forward

Changes made to the original puzzle should not be reflected in the copy, and vice versa. >>> p = create_puzzle(3, 3)>>> p2 = p.copy()>>> p.get_board() == p2.get_board()True >>> p = create_puzzle(3, 3)>>> p2 = p.copy()>>> p.perform_move(1, 1)>>> p.get_board() == p2.get_board()False In the LightsOutPuzzle class, write a method successors(self) that yields all successors of the puzzle as (move, new-puzzle) tuples, where moves themselves are (row, column) tuples. The second element of each successor should be a new LightsOutPuzzle object whose board is the result of applying the corresponding move to the current…arrow_forwardPlease complete the code as given!arrow_forwardDon't give me AI generated answer or plagiarised answer.
