Java "setTimeout" equivalent. (Credit: Oleg Mikhailov, http://stackoverflow.com/a/36842856)

JavaSetTimeout.java

// Asynchronous implementation with JDK 1.8:
public static void setTimeout(Runnable runnable, int delay){
    new Thread(() -> {
        try {
            Thread.sleep(delay);
            runnable.run();
        }
        catch (Exception e){
            System.err.println(e);
        }
    }).start();
}

// To call with lambda expression:
setTimeout(() -> System.out.println("test"), 1000);

// Or with method reference:
setTimeout(anInstance::aMethod, 1000);

// To deal with the current running thread only use a synchronous version:
public static void setTimeoutSync(Runnable runnable, int delay) {
    try {
        Thread.sleep(delay);
        runnable.run();
    }
    catch (Exception e){
        System.err.println(e);
    }
}
//Use this with caution in main thread – it will suspend everything after the call until timeout expires and runnable executes.
