Calculate the time spent to execute your program

Question

Hi
I have a pgm which calculates the response time in milllisecond using method System.currentTimeMillis(). And I get answer 0.
My question is If we measure the time in terms of nanosecond, do you think we still get zero answer?and What is your explanation for that?
Waiting for reply. Thanks in Advance
Regards,
Jyoti

Answer 1

Hi,
Here is the code for calculating the response time.
public class RunLinkedEvenOddList {
     public static void main(String[] args) {
          long time1;
          long time2;
          time1 = System.currentTimeMillis();
          System.out.println("Program 2 output:");
LinkedEvenOddList eolist = new
ew LinkedEvenOddList();
          eolist.insert(9);
          eolist.insert(4);
          eolist.insert(3);
          eolist.insert(2);
          eolist.insert(5);
          eolist.print();
          System.out.println("print Even:");
          eolist.printEven();
          System.out.println("print Odd:");
          eolist.printOdd();
          eolist.delete(9);
          eolist.delete(1);
          System.out.println("list after delete 9, 1:");     
          eolist.print();
          System.out.print("execute isMemeber(3): ");
          System.out.println(eolist.isMember(3));
          time2 = System.currentTimeMillis();
System.out.println("The starting time: " + time1 +
+
                    " milli seconds.");
          System.out.println("The ending time: " + time2 +
                    " milli seconds.");
Answer the following questions based on the output of
your code:
1. Calculate the time spent to execute your program
based on the value of time1 and time2; you need write
your formula first and then give the answer in
millisecond.
Answer:
time2-time1
time spent to execute your program = 0 millisec
2. If we measure the time in terms of nanosecond, do
you think we still get zero answer?
Answer:
3.What is your explanation for that?
