I have "Creator" class that has anonymous inner runnable class that creates threads. I also have GUI class that creates GUI and on button press executes the "Creator" class. But then my GUI freezes until all threads created by "Creator" are completed. I found that SwingWorker could help me in this situation, but I fail to understand how to create one in this particular situation. And is there any other easy way to do that, than SwingWorker?
Here is the code for my Creator class:
public class Creator {
final ExecutorService es;
Collection<Future<?>> futures = new LinkedList<>();
public Creator() {
es = Executors.newFixedThreadPool(10);
}
public void runCreator() {
for (int i = 0; i < 100; i++) {
futures.add(es.submit(new Check(i)));
}
es.shutdown();
for (Future<?> future : futures) {
try {
future.get();
} catch (Exception ex) {
}
}
}
private class Check implements Runnable {
private int i;
private Check(int i) {
this.i = i;
}
@Override
public void run() {
System.out.println("Number: "+i);
try {
Thread.sleep(1000);
} catch (InterruptedException ex) {
}
}
}
}
