java.lang.Process.waitFor()方法将导致当前的线程等待,如果必要的话,直到由该Process对象表示的进程已经终止。此方法将立即返回,如果子进程已经终止。如果子进程尚未终止,则调用线程将被阻塞,直到子进程退出。 public class ProcessDemo { public static void main(String[] args) { try { // create a new process System.out.println("Creating Process..."); Process p = Runtime.getRuntime().exec("notepad.exe"); // cause this process to stop until process p is terminated p.waitFor(); // when you manually close notepad.exe program will continue here System.out.println("Waiting over."); } catch (Exception ex) { ex.printstacktrace(); } } }
