Please write a Java program with at least two classes. Use a circle to represent it! The class should have at least one non-static setter method and one non-static getter. Implement at least one method test that invokes the setter method and the corresponding getter method so that the value out == the value in!

In java i have a class calle rational the input i receive is in yellow and the output is supposed to look like what comes after the yello

Pls help on this questions ASAP

Write the Java class named Paint that has/should do the following: 1. Three properly encapsulated variables: brand of type String, code of type int, and color of type String. 2. A constructor that takes two parameters and sets the brand and color instance variables. The code should be set to the number of characters in brand plus the number of characters in color. For example, if brand is "Bear" and color is "red", then code is set to 7 (because 4 + 3 = 7). 3. A default constructor that sets brand to "Bear", color to "Base", and code to 0. 4. A getter method and setter method for the code variable. 5. Correctly override the equals method to test if two Paint objects are equal. Make sure to handle null and type checks appropriately. Two Paint objects are equal if all of their instance variables are equal. 6. Override the toString method to return the values of the color, brand and code instance variables in that order, separated by spaces.

USING JAVA: Part A) Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An Appointment has a description (for example, "See the dentist") and a date. Write a method, occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.

Use the scenario below for help answering 1(A), (B) and (C). This is using Java. The Scenario: You have a class named HeartsPlayer A round of Hearts starts with every player having 13 cards Players then choose 3 cards to "trade" with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep) Players then strategically play cards in order to have the lowest score At the end of the round, points are cumulatively totaled for each player. If one player’s total is greater than 100, the game ends and the player with the lowest score wins. Guide: Static & Not Final Field: Accessed by every object, Changing Non-Static & Final Field: Accessed by object itself, Non-Changing Static & Final: Accessed by every object, Non-Changing Non-Static & Not Final Field: Accessed by object itself, Changing 1. How should the following data fields be defined (with respect to final and static)? (a) playerPosition (These have values of North, South, East, or West)- Is...

in JAVA Assume that a receipt id contains characters that represent information or that can be used as a code to determine something about the purchase. For example: if an id has an 'x' followed by two 'y's, it means that the purchase was a final sale and cannot be returned. Or if an id has an 'a' followed by three 'b's, it means that a coupon was used for purchase. Write a static method for the Receipt class to test whether a receipt id meets such a criteria. Does the id meet the criteria? The criteria is described by three pieces of data, passed in as parameters: char firstTarget char second Target int countOfSecond After First A receipt id meets the criteria if: the id contains the first target character and the second target character appears exactly the specified number of times after the first target character appears Note: the first and second char could be the same char! Carefully review the provided driver program for examples of ids that meet and don't meet criteria. For full...

Can you help me with my java exercise

Could you please help me with this Exercise? The language is JAVA. Thank You! Exercise 11.4 A "rational number" is a number that can be represented asthe ratio of two integers. For example, 2/3 is a rational number, and you canthink of 7 as a rational number with an implicit 1 in the denominator. The purpose of this exercise is to write a class definition that includes a va-riety of methods, including constructors, static methods, instance methods, modifiers, and pure methods:1. Define a class called Rational. A Rational object should have twointeger instance variables that store the numerator and denominator.2. Write a constructor that takes no arguments and sets the numerator to0 and denominator to 1.3. Write an instance method called printRational that displays a Rationalobject in a reasonable format. 11.10 Exercises 199 4. Write a main method that creates a new object with type Rational,sets its instance variables to the values of your choice, and displays theobject.5. You now have...

write the following 3 classes for the Java program so that this program produces the sample output shown at the end of Main. ElectricCar: a vehicle with a limited range. So it must be a subclass of Vehicle, and it must implement LimitedRange. Thus it needs an instance variable for its range, and a travel method (required by Vehicle. Please use @Override) that outputs "Zoom!" if it has enough range to go the distance specified (and update its range). It must have a constructor with 3 arguments as called by main. It also needs a getCurrentRange method as required by LimitedRange (use @Override for this too). Motorboat: a vehicle with a limited range. So it is similar to ElectricCar, but it outputs "Wisshhh!" when it goes. Sailboat: a vehicle that doesn't have a limited range. So it is a subclass of Vehicle, but doesn't implement LimitedRange. It can go any distance, and outputs "Weee!" when it travels. Code: class Main { publicstaticvoid main(String[] args) { Vehicle[]...

Programing language is Java. Define a class Person that represents a person. People have a name, an age, anda phone number. Since people always have a name and an age, your class shouldhave a constructor that has those as parameters. Define a toString() method whichdisplays all of the relevant information using a format like this: "Jim Lahey - Age 57- Phone 9025555555".
