There are two ways to monitor threads, programmatically and using the external tools. We have already seen how the result of a worker calculation could be checked. Let's revisit that code. We will also slightly modify our worker implementation:
class MyRunnable03 implements Runnable {
private String name;
private double result;
public String getName(){ return this.name; }
public double getResult() { return this.result; }
public void run() {
this.name = Thread.currentThread().getName();
double result = IntStream.rangeClosed(1, 100)
.flatMap(i -> IntStream.rangeClosed(1, 99999))
.takeWhile(i -> !Thread.currentThread().isInterrupted())
.asDoubleStream().map(Math::sqrt).average().getAsDouble();
if(!Thread.currentThread().isInterrupted()){
this.result = result;
}
}
}For the worker thread identification, instead of custom ID, we now use the thread name assigned automatically at the time of the execution (that is why we...
