2. Consider a class Time that represents a time of day. It has attributes for the hour and minute. The hour value ranges from 0 to 23, where the range 0 to 11 represents a time before noon. The minute value ranges from 0 to 59. a. Write a default constructor that initializes the time to 0 hours, O minutes. b. Write a private method isValid (hour, minute) that returns true if the given hour and minute values are in the appropriate range. C. Write a method setTi me (hour, minute) that sets the time if the given values are valid. d. Write another method setTime (hour, minute, isAM) that sets the time if the given values are valid. The given hour should be in the range I to 12. The parameter isAm is true if the time is an a.m. time and false otherwise

- Write a method toString() for the Cow class which displays information about a Cow object. The method should consider the following: • If the Cow's stomach value is 100, the output should say that the Cow is full • If the Cow's stomach value is below 100 but above 50, no information about the Cow's stomach should be given • If the Cow's stomach value is below 50 but above 10, the output should mention that the cow is hungry • If the Cow's stomach value is below 10, the output should mention that the cow is starving. Example output: First Cow is full. Second Cow Third Cow is hungry. Fourth Cow is starving!Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66Modify the Date class below by adding a new method called nextDay() that increments the Date by 1 when called and returns a new Date object. This method should properly increment the Date across Month boundary (i.e from the last day of the month to the first day of the next month). //Date class declaration public class Date { private int month; // 1-12 private int day; // 1-31 based on month private int year; // any year private static final int [] daysPerMonth = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; //constructor: confirm proper value for month and day given the year public Date (int month, int day, int year) { //check if month in range if (month <=0 II month > 12) { throw new IllegalArgumentException( “month (“ + month + “) must be 1-12”); } //check if day in range for month if…
- The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }Modify the Date class below by adding a new method called nextDay() that increments the Date by 1 when called and returns a new Date object. This method should properly increment the Date across Month boundary (i.e from the last day of the month to the first day of the next month). //Date class declaration public class Date { private int month; // 1-12 private int day; // 1-31 based on month private int year; // any year private static final int [] daysPerMonth = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; //constructor: confirm proper value for month and day given the year public Date (int month, int day, int year) { //check if month in range if (month <=0 II month > 12) { throw new IllegalArgumentException( “month (“ + month + “) must be 1-12”); } //check if day in range for month if…Write an equals method for the Car class given here. Two Cars are equal if their Vehicle Identification Numbers (VIN) are the same. HINT: The String class has an equals method that can be called from the Car class equals method.
- Slide Type Slide • Exercise # 1: Define a class Point that represents a point in 2 – D plane. The point has x and y coordinates. Define the following: • A constructor to initialize the x, y coordinates. • A method translate(self, dx,dy) to translate the point object dx , and dy units in x and y directions, respectively. • A method distanceTo (self, point2) to return the distance between the point referenced by self and point2. • getX(self) to return the value of x coordinate. • getY(self) to return the value of y coordinate Test the above class by: • Creating 2 point objects; one with (3,5) as x,y coordinates; the second with (-10,30) as x,y coordinates. • Move the first point 5.5 units in x direction and -12.5 units in y direction using translate method • Find the distance between the 2 points in their current location using distance To method A Sample output resulting from running the above test class is shown below new coordinates of point1= (8.5 , -7.5) Coordinates of point 2 =…The weight of an object can be described by two integers: pounds and ounces (where 16 ounces equals one pound). Class model is as follows: public class Weight { private int pounds; private int ounces; public Weight(int p, int o) ( pounds=p+o/16: ounces = 0% 16: } Implement a method called subtract, which subtracts one weight to another. i.e. Weight w1 = new Weight(10.5): Weight w2 = new Weight(5.7): Weight w3= w1.subtract(w2):Java Programming: Write a static method named urgentAndIncomplete. Write the method as if it is in Main.java (not part of the ToDoItem class). The method should: Accept three ToDoItem references as parameters, and Return an int. Count how many of the ToDoItems meet two criteria: A priority greater than 3 Not completed The method should return how many of the parameters meet these criteria. That will be either 0, 1, 2, or 3.
- Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…FOR JAVA Create a class named Product that has ID, price and stock as fields. This class must have two constructors; one constructor must take all its fields as parameters, second constructor must take ID and price as parameters and set stock to 0. Also implement the following methods: • String toString(): Returns a brief summary about the object. • void sell(int): Takes a parameter that represents the amount to sell. Checks if stocks are sufficient. If so, it updates the stock and prints the total price. Else it prints a warning to user. Create 3 instances of Product class and test your methods.The weight of an object can be described by two integers: pounds and ounces (where 16 ounces equals one pound). Class model is as follows: public class Weight { private int pounds; private int ounces; public Weight(int p. int o) { else pounds = p + o/16: ounces = 0 % 16: } Implement a method called compareTo, which compares the weight of one object to another. i.e. Weight w1 = new Weight(10,5): Weight w2 = new Weight(5,7): if(w1.compareTo(w2) >0)
