下面是一个示例代码: Instantinstant1=Instant.now();// 第一个时间戳Instantinstant2=Instant.now();// 第二个时间戳longdiffInSecs=Duration.between(instant1,instant2).getSeconds();// 计算两个时间戳之间的秒数差System.out.println("The differenc
longadd(long instant, long value) Adds a duration value (which may be negative) to the instant. intgetDifference(long minuendInstant, long subtrahendInstant) Computes the difference between two instants, as measured in the units of this field. ...
Obtains a Duration representing the duration between two instants. This calculates the duration between two temporal objects of the same type. The difference in seconds is calculated using Temporal#until(Temporal,TemporalUnit). The difference in nanoseconds is calculated using by querying the ChronoUnit...
方法名:between Duration.between介绍 [英]Obtains an instance of Duration representing the duration between two instants. Obtains a Duration representing the duration between two instants. This calculates the duration between two temporal objects of the same type. The difference in seconds is calculated ...
If we look at the code it makes perfect sense. We get a timestamp at the start and we get another timestamp when the code finished. Time elapsed is the difference between these two values. However,the result may and will be inaccurate asSystem.currentTimeMillis()measureswall-clocktime.Wall...
The following example creates two local times for the timezones defined above. Then we compare both times and calculate the difference in hours and minutes between both times.LocalTime now1 = LocalTime.now(zone1); LocalTime now2 = LocalTime.now(zone2); System.out.println(now1.isBefore(now...

Windows下,http://jdk.java.net/java-se-ri/11下载压缩包后解压,打开目录,bin目录里面就是java所有命令,javac编译java文件,产生.class文件,java运行编译好的class文件。怎样使用命令呢?配置环境变量,还要配置一下CLASSPATH,网上有太多配置教程,就不说了。Ubuntu安装JDK,sudo apt update,然后sudo apt install open...
To take into account the difference between the offsets, and adjust the time fields, use withOffsetSameInstant(java.time.ZoneOffset). This instance is immutable and unaffected by this method call. Parameters: offset - the zone offset to change to, not null Returns: an OffsetTime based on ...
The duration is measured in "seconds", but these are not necessarily identical to the scientific "SI second" definition based on atomic clocks. This difference only impacts durations measured near a leap-second and should not affect most applications. SeeInstantfor a discussion as to the meaning...
