Calculate Execution time in Java

Following is the easiest way to find the execution time of a code block:

1. Get the start time before the code block:

long startTime = System.currentTimeMillis();

2. Get the end time after the code block:

long endTime = System.currentTimeMillis();

3. Calculate the time difference:

   long secsTaken = (endTime - startTime); // unit is millisecond

4. Convert to required unit (Eg: Second):

  long secsTaken =secsTaken / 1000;
