JavaUtils

JavaUtils is a collection of small utility classes. It includes tools to pause a thread with finer control than the standard tools, and to measure elapsed time.

Maven configuration

		<groupId>net.digger</groupId>
		<artifactId>utils</artifactId>
		<version>1.0.0</version>
	</dependency>

Pause

Pause is a tool to pause a thread for a period of time, with finer control than the standard tools. For example, you could call

	TimeUnit.MICROSECONDS.sleep(micros);

or

	TimeUnit.NANOSECONDS.sleep(nanos);

but currently both of those internally just call

	Thread.sleep(millis);

so you don't have any control below 1 millisecond.

Pause gives you control well below that threshold, down to microseconds and makes a good effort at nanoseconds. Precision at that level depends on your machine and your JVM. I get good results down to around a few tens of microseconds. Your results may vary.

Usage

	Pause.second(seconds);

	Pause.milli(milliseconds);

	Pause.micro(microseconds);

	Pause.nano(nanoseconds);

Timer

A simple little tool to quickly check the elapsed time for a block of code.

Usage

	long elapsed = Timer.time(() -> {
		// your code here
	});
