How to convert nanoTime to seconds in java?

How to convert nanoTime to seconds in java?

We can just divide the nanoTime by 1_000_000_000 , or use the TimeUnit. SECONDS.

What is nanoTime in Java?

nanoTime() method returns the current value of the most precise available system timer, in nanoseconds. The value returned represents nanoseconds since some fixed but arbitrary time (in the future, so values may be negative) and provides nanosecond precision, but not necessarily nanosecond accuracy.

What does nanoTime do?

nanoTime. Returns the current value of the running Java Virtual Machine’s high-resolution time source, in nanoseconds. The value returned represents nanoseconds since some fixed but arbitrary origin time (perhaps in the future, so values may be negative).

How do you convert milliseconds to seconds in Java?

Take Input in milliseconds. Convert Milliseconds to minutes using the formula: minutes = (milliseconds/1000)/60). Convert Milliseconds to seconds using the formula: seconds = (milliseconds/1000)`). The print output from Milliseconds to minutes and seconds.

How to convert system.nanotime to seconds in Java?

Java – How to convert System.nanoTime to Seconds. We can just divide the nanoTime by 1_000_000_000, or use the TimeUnit.SECONDS.convert to convert it.

How to convert milliseconds to minutes and seconds in Java?

In the above program, we have used the long datatype to store milliseconds, minutes, and seconds values. It is because the toMinutes () and toSeconds () methods return values in long. Note: To use the methods, we must import the java.util.concurrent.TimeUnit package.

How to convert nanoseconds to seconds using TimeUnit?

Using TimeUnit will not output fractions of a second, instead returning 0. If you don’t want to use a hard coded 10 digit number then use something like 1E9. For example : double seconds = ( (double) nanoseconds) / 1E9; I would do this every time as a personal preference. – TechTrip Aug 14 ’14 at 3:48

What’s the difference between nano time and elapsed time?

Besides, nanoTime is shorter to type anyway. Calculating elapsed time basically comes down to start a timer just before the method execution and at the end of the method execution. You stop the timer and calculate the difference. Here is a basic example to calculate the elapsed time. Here is a method to calculate the elapsed time between two dates.
