Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.
Convert the following UML diagram into the Java code. Write constructor, mutator and accessor methods for the given class. Create an instance of the class in a main method using a Demonstration class. Note: The structure of the class can be compiled and tested without having bodies for the methods. Just be sure to put in dummy return values for methods that have a return type other than void. Exercise Log ExerciseID: integer ExerciseCategory: string TimeSpent: float Calories: float
ANSWER IN JAVA Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.

Write Java code for a Baby class. A Baby has a name of type String and an age of type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supply methods for setting the name, setting the age, getting the name and getting the age.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values from the instance variables must be done with get methods. The set method for the name instance variable should ensure that the input is not empty or contain whitespaces (otherwise set a default value). The set method for the age instance variable should validate the input to be between 1 and 4 inclusive(otherwise set a default value).Give Java code for an equals method for the Baby class. Babies count asbeing the same (i.e. equal) if their…
Please answer the question in the screenshot. The language used is Java. Please provide the code to the question with an explanation. Please use the below code as a starting point. import java.util.*; public class CoursePlanner {// this method prints out: whether it is possible to take all the given courses and// one possible schedule for the given coursespublic static void plan(int numberOfCourses, int[][] prerequisites) {return;} // this is a helper method for plan; it returns a boolean to indicate if a given series of courses can be possibly scheduledpublic static boolean check(int numberOfCourses, int[][] prerequisites) {// remove these two linesif (RightSolution.check(numberOfCourses, prerequisites)) return false;else return true;}}
Write a Java Program, Create a class with a method that prints "This is parent class" and its subclass with another method that prints "This is child class". Now, create an object for each of the class and call 1 - method of parent class by object of parent class 2 - method of child class by object of child class 3 - method of parent class by object of child class In the above example, declare the method of the parent class as private and then repeat the first two operations (You will get error in the third).
Let’s put your knowledge into practice. Complete the following questions:1. Create a class named 'Student' with String variable 'name' and integer variable 'roll_no'. Assign the value of roll_no as '2' and that of name as"John" by creating an object of the class Student.2. Assign and print the roll number, phone number and address of two students having names "Sam" and "John" respectively by creating two objectsof class 'Student'.3. Write a program to print the area of a rectangle by creating a class named 'Area' having two methods. First method named as 'setDim' takes lengthand breadth of rectangle as parameters and the second method named as 'getArea' returns the area of the rectangle. Length and breadth ofrectangle are entered through keyboard.4. Create a class named 'PrintNumber' to print various numbers of different datatypes by creating different methods with the same name 'printn'having a parameter for each datatype.5.
