Close the public class definition.

Program Description Answer

Program Description:

The following java program has the class named Time and shows the current time with the data fields hour, minute and second respectively.

Explanation of Solution

Program:

//Class definition

public class Time {

//Define main function

public static void main(String[] args) {

//Create object to the class and assign the arguments

MyTime time1 = new MyTime();

//Print the data field

System.out.println(time1.getHour() + ":" +

time1.getMinute() + ":" + time1.getSecond());

//Create object to the class and assign the arguments

MyTime time2 = new MyTime(555550000);

//Print the data field

System.out.println(time2.getHour() + ":" +

time2.getMinute() + ":" + time2.getSecond());

//Create object to the class and assign the arguments

MyTime time3 = new MyTime(5, 23, 55);

//Print the data field

System.out.println(time3.getHour() + ":" +

time3.getMinute() + ":" + time3.getSecond());

}

//Class definition

class MyTime {

//Define the integer

private int hour;

private int minute;

private int second;

//Declare public function

public MyTime() {

this(System.currentTimeMillis());

}

//Declare public method

public MyTime(long elapsedTime) {

//Define setter method

setTime(elapsedTime);

}

//Pass the arguments to the public function

public MyTime(int hour, int minute, int second) {

this.hour = hour;

this.minute = minute;

this.second = second;

}

//Define getter method

public int getHour() {

return hour;

}

//Define getter method

public int getMinute() {

return minute;

}

//Define getter method

public int getSecond() {

return second;

}

//Define void function

public void setTime(long elapsedTime) {

// Obtain the total seconds since the midnight, Jan 1, 1970

long totalSeconds = elapsedTime / 1000;

// Compute the current second in the minute in the hour

second = (int)(totalSeconds % 60);

// Obtain the total minutes

long totalMinutes = totalSeconds / 60;

// Compute the current minute in the hour

minute = (int)(totalMinutes % 60);

// Obtain the total hours

int totalHours = (int)(totalMinutes / 60);

// Compute the current hour

hour = (int)(totalHours % 24);

}
