Question

JAVA Design a class named Clock. You should use your IDE for this exercise. The class contains private data fields for startTime and stopTime, a no argument constructor that initializes the startTime to the current time, a method named start() that resets the startTime to the given time, a stop() method that sets the endTime to the given time and a getElapsedTime() method that returns the elapsed time in seconds. Create a TestClock class to construct a Clock instance and return the elapsed time. Command line arguments should be used to send the start and end times. You should use the java.time classes. Here is sample run: java TestClock 11:45:12 11:48:13 Elapsed time in seconds is: 181 THIS MUST BE COMPLETED AS ONE JAVA FILE!!!!!!!!!!!

Explanation / Answer

Hey heres your code :

import java.util.*;
import java.text.*;

public class TestClock {
static long startTime,endTime;
public TestClock() {
Date date = new Date();
long startTime=date.getTime();

}
public static void main(String args[]) {
TestClock test=new TestClock();
String s=args[0];
start(s);
String s1=args[1];
stop(s1);
long elapsed=getElapsedTime();
System.out.println(elapsed);

}
public static void start(String s)
{
SimpleDateFormat ft = new SimpleDateFormat ("HH:mm:ss");

      String input = s;

     

      Date t;
try {
            Date parseDate = ft.parse(input);
            startTime=parseDate.getTime();
        }
        catch (ParseException e) {
            ;
        }
}
public static void stop(String s)
{
SimpleDateFormat ft = new SimpleDateFormat ("HH:mm:ss");

      String input = s;

     

      Date t;
try {
            Date parseDate = ft.parse(input);
            endTime=parseDate.getTime();
        }
        catch (ParseException e) {
            ;
        }
}
public static long getElapsedTime()
{
long diff=(endTime-startTime)/1000;
return diff;
}
}
