2024/10/12 -The value returned represents nanoseconds since some fixed but arbitrary origin time (perhaps in the future, so values may be negative).
2024/8/7 -System.nanoTime() Method is a Java Environment, which is a high-definition time pool in the nanosecond unit. This method always returns the current value.
2025/3/26 -Another pitfall with nanoTime() is that even though it provides nanosecond precision, it doesn't guarantee nanosecond resolution (i.e. how often the value is ...
2024/10/15 -For measuring time intervals (durations) use System.nanoTime() . It's as close to an idea of a monotonic clock as it can be. Values returned by this method can ...

Q.C言語でtime.hを用い、計測したい処理の前後をclock関数で挟み、処理時間を算出していたのですが、何回やっても5.00のように小数点以下が00で固定化されています。 JAVAでnanoTi...
A.(ID非公開) どんなコードを書いたのかが秘密では判断できません。 time()関数もclock()関数の整数を返すので「終了時間ー開始時間」の 答えは整数になります、小数点以下は得られません。

2025/4/8 -With nanosecond precision, nanoTime() delivers superior accuracy for code profiling and performance measurement, making it essential for timing critical ...
2024/12/4 -nanoTime() provides the highest resolution (nanosecond level) timer for measuring how long a task takes in Java. Note that it is more suitable for measuring ...
2025/2/11 -The two most straightforward methods for timing are System.currentTimeMillis() and System.nanoTime() . Both are part of the Java standard library and offer ...
2024/10/12 -I want to know the working time of some methods in my study project by Java tools. When I tried to use System.nanoTime(), I had noticed, that comparison of the ...
