What is the difference between asynchronous and synchronous in java

Difference

1. The difference between asynchronous and synchronous is generally whether the caller needs to wait for the result.

2. Do you need to wait for the result to be synchronized?

3. You can also decide whether you need to wait for the result to be asynchronous.

Example

--异步 Thread t3 = new Thread(new Runnable() { @Override public void run() { try { for (int i = 0; i < 10; i++) { Thread.sleep(1100); System.out.println("4:" + i); } } catch (Exception e) { e.printStackTrace(); } } });t3.start(); --同步 SwingUtilities.invokeAndWait(new Runnable() { @Override public void run() { // TODO Auto-generated method stub } }); t3.isAlive()
