isBefore back to summary

isBefore	back to summary
public static boolean isBefore(long nanoTime1, long nanoTime2) Returns whether the first nanoTime is strictly before the second nanoTime. Reads as: `"is nanoTime1 strictly before nanoTime2?"`. Avoids the common mistake of comparing the 2 nanoTimes with the less-than `<` operator, which cannot be used when comparing nanoTimes, as specified in `System#nanoTime()`. Parameters nanoTime1:long the first nanoTime nanoTime2:long the second nanoTime Returns:boolean whether the first nanoTime is strictly before the second nanoTime See Also `isBeforeOrSame(long, long)`
