Concurrency in Go: Java Executors

ExecutorService executor = Executors.newFixedThreadPool(4);
for (int i = 0; i < 10; i++) {
    executor.execute(() -> {  
        //No Java without boilerplate!     
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {}
        System.out.println("Finished");
    });
}
executor.shutdown();
