Chapter 12.1, Problem 5STE
Suppose you want to change the implementation of the class DigitalTime given in Displays 12.1 and 12.2. Specifically, you want to change the way the time is recorded. Instead of using the two private variables hour and minute, you want to use a single (private) int variable, which will be called minutes. In this new implementation, the private variable minutes will record the time as the number of minutes since the time 0:00 (that is, since midnight). So 1:30 is recorded as 90 minutes, since it is 90 minutes past midnight. Describe how you need to change the interface and implementation files shown in Displays 12.1 and 12.2. You need not write out the files in their entirety; just indicate what items you need to change and how, in a very general way, you would change them.

I am trying to add int instance variables for the current hour and minutes of a clock, and I am trying to make them private. I am also trying to write getHour and getMinutes getter methods for these instance variables. I would like to know if I did this correctly and if not, I would like assistance as to what I could change.
public class DigitalClock {
private int currentHour; private int currentMinutes;
public int getHour() { return currentHour; }
public void setHour(int currentHour) { this.currentHour = currentHour; }
public int getMinutes() { return currentMinutes; }
public void setMinutes(int currentMinutes) { this.currentMinutes = currentMinutes;}}
Implement the design of the Bird class so that the following output is produced:
# Write your codes here.print(“No.of Bird=”, Bird.count)ostrich = Bird('Ostrich')duck = Bird("Duck", True)owl = Bird('Owl', True)print(“###########################”)ostrich.fly()duck.fly()owl.fly()duck.setType('Water Birds')owl.setType('Birds of Prey')print(“=========================”)ostrich.printDetail()print(“=========================”)duck.printDetail()print(“=========================”)owl.printDetail()print(“=========================”)print(“No.of Bird=”, Bird.count)
Output:No.of Bird= 0###########################Ostrich can not flyDuck can flyOwl can fly===========================Name: OstrichType: Flightless Birds=========================== Name: DuckType: Water Birds===========================Name: OwlType: Birds of Prey===========================No.of Bird= 3
Write a program in the Java language requires the management of university students, where student data (name, student number, and specialization) are saved, and then he can add and delete study materials for the current semester, and you can also add the grade for each subject (with the addition of the final code for the degree automatically).Note: The class principle is used to solve this assignment.

- Write a full java code with input out example in OOP style that does the following: Given below is a Rectangle class consisting of an upper left coordinate and a lower right coordinate. class Rectangle { int upperLeftX; int upperLeftY; int lowerRightX; int lowerRightY; } Since the upper left coordinate and lower right coordinate comprise of points, how would you modify the definition of the Rectangle class to include these points in your class? write a complete java code to do this , not only the classes. Hint: You can create a Point class to store the x and y coordinates of the upper left and lower right points and use composition to include the upper left and lower right points inside the Rectangle class, as objects of the Point class.arrow_forwardIn Java, Use the Phone class as a baseline, and write a method isUSA. It should return true if the country code is 1 and false otherwise. Also expanding the Phone class, write a method that determines the location of an area code.

The method should return a new String object that represents the text you would end up with if the argument String were "added onto the end of" this String.
