OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
JAVA:
Transcribed Image Text:Use the following class definition to answer the questions below.
public class Clock implements Daylight Savings Time {
// Clocks represent time by storing the hour, minute, and second portions of the current tim
e separately
private int currentHour;
private int currentMinute;
private int currentSecond;
}
public clock() {
}
public Clock(int h, int m, int s) {
currentHour = 0;
currentMinute = 0;
currentSecond = 0;
updateTime (h, m, s);
}
public void updateTime(int h, int m, int s) {
currentSecond = currentSecond + s;
while (currentSecond > 60) {
currentSecond = current Second - 60;
currentMinute++;
}
currentHour = 0;
currentMinute = 0;
currentSecond = 0;
}
}
currentMinute = currentMinute + m;
while (currentMinute > 60) {
}
}
currentMinute = currentMinute - 60;
currentHour++;
@Override
public void springForward() {
currentHour = currentHour + h;
currentHour = currentHour % 24;
currentHour++;
currentHour = currentHour % 24;
@Override
public void fallBack() {
currentHour--;
currentHour = currentHour % 24;
}
public void printTime() {
System.out.println(currentHour + ":" + currentMinute + + currentSecond);
Does the Clock class represent time in 12-hour format or 24-hour format? (12-hour
format means there is 6:00 am and 6:00 pm; 24-hour format means those same times are
shown as 6:00 and 18:00)
• Is DaylightSavingsTime a concrete class, abstract class, or interface? Which methods does
the Clock class inherit from DaylightSavingsTime?
• If the Clock is currently storing the time of 1:00:00 (currentHour = 1, currentMinute = 0,
currentSecond = 0), and the updateTime() method is called with the arguments 2, 30, and
O respectively, what will be the Clock's time after the method completes? (You can answer
this either as a time or by showing the values of the variables.)
• Is it possible for the printTime() method to ever show the time as "25:99:99"? Why or why
not?
