Is this because the .bat file contains

When using implicit waits, as advised here , I still sometimes want to assert the immediate invisibility or non-existence of elements. In other words, I know some elements should be hidden, and want my tests make that assertion fast , without spending several seconds because of the (otherwise useful) implicit wait. One thing I tried was a helper method like this: // NB: doesn't seem to do what I want private boolean isElementHiddenNow(String id) { WebDriverWait zeroWait = new WebDriverWait(driver, 0); ExpectedCondition<Boolean> c = invisibilityOfElementLocated(By.id(id)); try { zeroWait.until

今天在网上看到一段代码，是模拟银行转账的，如何保证多次转账并发执行的时候，转出账户和转入账户的金额一致。 代码可谓巧妙绝伦！先看代码： public class MyLock { public static void main(String[] args) { // 模拟转出和转入账户 Account src = new Account(100000); Account target = new Account(100000); // 设置倒计时 CountDownLatch countDownLatch = new CountDownLatch(99999); for (int i = 0; i < 99999; i++) { Thread t1 = new Thread(() -> { // 每次转1元钱，共转9999次 src.transactionToTarget(1, target); countDownLatch.countDown(); }); t1.setName("Thread: " + i); t1.start(); } try { // 等待所有线程执行完毕 countDownLatch.await(); } catch (InterruptedException e) { e.printStackTrace(); } // 打印账户余额 System.out

sleep是Thread类的方法 wait是object类中定义的方法

I want to wait 5 seconds before starting another public void method. The thread sleep was not working for me. If there is a way of wait() without using Threads I would love to know that. public void check(){ //activity of changing background color of relative layout } I want to wait 3 seconds before changing the relative layout color. just add one-liner with lambda (new Handler()).postDelayed(this::yourMethod, 5000); See if this works for you. Be sure to import the android.os.Handler Handler handler = new Handler(); handler.postDelayed(new Runnable() { public void run() { // yourMethod(); } },

When using a wait in an AsyncTask , I get ERROR/AndroidRuntime(24230): Caused by: java.lang.IllegalMonitorStateException: object not locked by thread before wait() Is it possible to use an Asynctask just for waiting? How? Thanks class WaitSplash extends AsyncTask<Void, Void, Void> { protected Void doInBackground(Void... params) { try { wait(MIN_SPLASH_DURATION); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } protected void onPostExecute() { waitSplashFinished = true; finished(); } } Flo Use Thread.sleep() instead of wait() .
