您必须使用线程才能实现此目的。线程是无害的：)下面的示例将一段代码运行10秒钟，然后结束它。
public class Test { public static void main(String args[]) throws InterruptedException { Thread thread = new Thread(new Runnable() { @Override public void run() { System.out.println("0"); method(); } }); thread.start(); long endTimeMillis = System.currentTimeMillis() + 10000; while (thread.isAlive()) { if (System.currentTimeMillis() > endTimeMillis) { System.out.println("1"); break; } try { System.out.println("2"); Thread.sleep(500); } catch (InterruptedException t) {} } } static void method() { long endTimeMillis = System.currentTimeMillis() + 10000; while (true) { // method logic System.out.println("3"); if (System.currentTimeMillis() > endTimeMillis) { // do some clean-up System.out.println("4"); return; } } }}
